Severe Thunderstorms and Excessive Rain in the Central U.S.; Critical Fire Weather in California

Scattered severe thunderstorms, associated with tornadoes, large hail, and damaging winds are likely today from the southern Plains into the Ozarks, and mid Mississippi Valley. Excessive rainfall is also likely in these areas. Gusty easterly winds and low relative humidity will support elevated to critical fire weather over coastal portions of California today into Thursday. Read More >

Summary

 

Fresh on the heels of the record-setting blizzard that occurred from January 31-February 1, 2011, another significant winter storm affected the southern Plains in early February 2011. Snowfall totals reached a foot over parts of northern Oklahoma, with widespread totals of 4 to 8 inches over the northern 2/3 of Oklahoma. Like the last winter storm, this storm affected several states, although this storm remained further to the south as it moved from Colorado and New Mexico, east into the southeastern United States.

 

National Weather Conditions during the early morning of February 8, 2011

A 1042 mb surface high pressure developed south out of Canada into Kansas early on February 8th behind a cold front that finally moved into northern Oklahoma during the late morning and early afternoon hours. Behind the arctic front were very cold temperatures, with temperatures falling into the single digits, and even sub-zero readings across many areas of the northern and central Plains (sub-zero temperatures would soon overspread much of Oklahoma). Precipitation, some of it heavy, developed behind the front as a strong low-level jet transported relatively warm and more moist air north over-top of the front. Snowfall totals north of the Oklahoma/Kansas border totaled 6 to 10 inches, with northerly surface winds gusting over 30 mph.

During the day, the cold front made substantially more southward progress over the Texas panhandle into western Oklahoma, with additional heavy snow accumulations developing behind the boundary by late afternoon. Additional support for precipitation development had developed ahead of a potent mid-level disturbance that moved southeastward toward Oklahoma. Normally, progressive storm systems, such as this one (open waves), are not big snow producers over the southern Plains. However, with strong warm advection and very cold temperatures at the surface and aloft (and getting colder through the event), the snow growth was maximized, which in turn caused moderate to heavy snowfall to occur.

National Weather Conditions during the mid afternoon of February 8, 2011

By mid evening of February 8th, the main snow band had developed over northern Oklahoma, with moderate to heavy snowfall occurring over the northern two or three tiers of counties for several hours. Here, widespread totals of 8 to 12 inches of snow were reported, with even higher totals toward northeast Oklahoma. Further to the south, an area of moderate to heavy snowfall progressed east, but started a little later and did not last near as long. This included the Oklahoma City metro, although Will Rogers World Airport still managed to pick up almost 6 inches of snow. Even further south toward the Red River, lighter totals of 2 to 4 inches occurred due to the even later onset and quicker progression of the precipitation.

In addition to the snowfall, a strong pressure gradient created very gusty winds behind the front. The strongest winds were reported over western Oklahoma, as pressure rises were maximized behind the quickly moving cold front. Gusts to almost 50 mph created wind chill values well below zero as temperatures fell into the lower teens, which also caused considerable blowing and drifting snow. Farther north and east, blowing and drifting snow also became a significant issue, even with slightly lower wind speeds. Wind gusts over 30 mph were reported at times, with visibilities falling to an 1/8 of a mile at times in the heavier snow bands.

Looking back, this storm was well forecast by models, which were remarkably consistent in painting a significant winter storm over the area. As a result, forecaster confidence was high enough that a Winter Storm Watch was issued well in advance of the storm (5:30 pm on 6th). Snowfall totals over 4 to 8 inches of snow, which covered a large area of Oklahoma into western north Texas. Further confidence the next day resulted in the Watch being upgraded to a Winter Storm Warning over our Oklahoma counties. The next day, the Warning was expanded to cover all but 2 counties in the NWS Norman County Warning Area (CWA).

With the advanced preparation and coordination leading up to the event, hundreds of schools and businesses closed on the 9th, which kept local traffic to a relative minimum. However, even with the images of the recent blizzard fresh in everyone’s mind, there were still several accidents/injuries associated with this storm. Around 240 injuries statewide were reported by the Oklahoma State Department of Health, with 33 injuries associated with around 84 automobile accidents. And, like last storm, there were fatalities (2) with this storm as compared to 4 deaths with the January 31-February 1, 2011 winter storm.

The storm added to the already impressive seasonal snowfall totals across Oklahoma and western north Texas. The reporting at Oklahoma City surpassed the previous snowfall record for February, and was 8th on the list for snowiest seasons. What makes this even more impressive is that over a 10-day period, two snow storms had deposited over 18 inches of snow at Will Rogers World Airport. The deep accumulations, which should slowly melt into the soil instead of washing off, will also help (slightly) with the ongoing drought that had developed over the last several months.

However, even though the storm had passed, ill effects from it continued during the early to mid morning hours of the February 10th. A deep snow pack, combined with clear skies and light surface winds produced very cold temperatures. Keeping with the theme of extremes during winter of 2010-2011, the low temperatures on the 10th were nothing short of frigid, and numerous sites set record low temperatures, including the all-time record low temperature for Oklahoma! By 10 pm on the 9th, some locations over northern Oklahoma were below -10 degrees. And by 7:30 am on the 10th, a wide area of -10 to -15 degrees was reported over the northern third of Oklahoma. A few of those sites were even below -20 degrees. Nowata broke the all-time low record for Oklahoma, falling to -31 degrees. The 2nd lowest were Pryor and Bartlesville ASOS site, also in northeastern Oklahoma, which both fell to -28 degrees. A complete list of low temperature records for February 10th in the NWS Norman CWA is also available in the Temperature Data tab. Oklahoma City also fell below zero, reaching -5 degrees around 7:00 am. This broke the previous record of 4 degrees reached in 1929. Wichita Falls, TX reached their record low temperature, although they remained slightly above zero. The temperature of 3 degrees broke the previous record of 5 degrees set in 1980.

Satellite Imagery

 

A visible satellite image at 9:15 AM CST on February 10, 2011 shows that almost all of the NWS Norman County Warning Area (CWA) was covered by snowfall.

Visible Satellite Image at 915 AM CST on February 10, 2011

Three days later, a visible satellite image at 915 AM CST on February 13, 2011 reveals that most of the snow had melted across the southern half of Oklahoma and western north Texas. However, even with warmer temperatures affecting the region, the deepest bands of snow were still quite evident.

Visible Satellite Image at 915 AM CST on February 13, 2011

The following images were created by and are available at the Cooperative Institute for Meteorological Satellite Studies (CIMSS website). A 1-km resolution MODIS 11.0 µm IR image at 02:16 AM on February 10, 2011 shows a detailed view of the cold surface IR brightness temperatures, which were as cold as -38º C over northern Oklahoma at that time.

The following CIMSS animated satellite image of 4-km resolution GOES-13 10.7 µm IR data shows a large region with very cold surface IR brightness temperatures during the early to mid morning hours of February 10, 2011 (darker blue color enhancement) over the snow-covered portions of Kansas and Oklahoma. The GOES-13 IR imagery also showed a few thin bands of cirrus cloud moving eastward across the region.

Temperature Data

 

Clear skies, light winds and several to many inches of snow cover dropped by the February 8-9, 2011 winter storm allowed several areas across northern Oklahoma to set all-time record low temperatures on February 10, 2011. The Mesonet site near Nowata in northeastern Oklahoma dropped to an amazing -31 degrees F! This established a new all-time record for the state of Oklahoma. Other locations across central and southern Oklahoma, as well across western north Texas also set daily record low temperatures. Below is a list of low temperature records that occurred on February 10, 2011. Note: This list only covers the National Weather Service Norman cooperative observer and ASOS sites over central and western Oklahoma, and western north Texas.

.DISCUSSION...
COMBINATION OF WIND AND VERY COLD TEMPERATURES WILL PRODUCE WIND
CHILL WELL BELOW ZERO IN A LOT OF AREAS OVER THE NEXT 24 HOURS.  
SO NO PLANS TO ADJUST WIND CHILL ADVISORY.  CURRENT WIND CHILLS IN
WARNING AREA RANGE FROM -17 TO -21 BELOW AND WILL LIKELY LET WARNING
EXPIRE AROUND MID-MORNING.  

SOME LIGHT ECHOS THIS MORNING BETWEEN LBB/MAF BUT ECHOS ARE HAVING 
A HARD TIME REACHING FAR WESTERN TEXAS COUNTIES. GFS INDICATES SOME
WEAK WAA AROUND 7H LATER THIS MORNING BUT EXPECT FLURRIES AT
BEST. WITH TROUGH/UPPER LOW MOVING FARTHER SOUTH TODAY...BETTER
OPPORTUNITY FOR CLOUD COVER SHOULD BE ACROSS WESTERN PARTS OF FA.

VERY COLD AIR THAT ORIGINATED OVER THE YUKON/NORTHWEST TERRITORIES
WILL BE SLOW TO MODIFY OVER THE NEXT FEW DAYS. WITH LIGHTER WINDS
AND FEW CLOUDS...AT LEAST NORTH...TEMPS SHOULD DIP WELL BELOW ZERO
WITH DECENT SNOW COVER. A NORTHERLY WIND COMPONENT AT OKC IS NOT
A FAVORABLE WIND FOR LOW MIN TEMPERATURES HOWEVER.  

NEXT TROUGH/UPPER LOW WILL LIFT ACROSS NORTH TEXAS/SOUTHEAST 
OKLAHOMA ON FRIDAY. LOW CLOUDS WILL LIFT NORTH INTO AT LEAST 
SOUTH CENTRAL/SOUTHEAST OKLAHOMA AHEAD OF THIS FEATURE...BUT
LITTLE IN ANY PRECIP SHOULD OCCUR.  

SATURDAY INTO SUNDAY SHOULD SEE TEMPERATURES WARM TO NEAR NORMAL
...BEFORE ANOTHER STRONG FRONT APPROACHES SUNDAY NIGHT INTO
MONDAY. EC MUCH FASTER WITH THE FRONT...BUT ENSEMBLE MEAN GIVES
SOME SUPPORT TO SLOWER 00Z GFS. SHORTWAVE THAT APPROACHES IN
NORTHWEST FLOW/ AND DECENT FRONTOGENETIC FORCING WILL SUPPORT
SOME SNOW/RAIN. SNOWFALL AMOUNTS WITH THIS SYSTEM WILL LIKELY
BE ON THE LIGHTER SIDE. DID ADJUST TEMPS DOWN SEVERAL DEGREES 
FOR HIGHS ON TUESDAY.

.DISCUSSION...
THE SNOW PACK CONTINUES TO KEEP SHORT RANGE MODELS BIASED TOO
WARM... SO TEMPERATURE GRIDS HAVE BEEN ADJUSTED MUCH COOLER.
AN UPPER LOW WAS SPINNING ACROSS NEW MEXICO. NAM AND ECMWF ARE IN
GOOD AGREEMENT WITH THE LOW DIGGING INTO OLD MEXICO... THEN
LIFTING NORTHEAST ACROSS WESTERN AND NORTHERN TEXAS ON FRIDAY. THE
ARRIVAL OF THE UPPER LOW WILL BRING LOW POPS OF -SN ACROSS
SOUTHEASTERN OKLAHOMA FOR FRIDAY. SATURDAY WILL BE A BRIEF
WARM UP... AS THE ARCTIC AIR WILL LIFT TO THE NORTH AND EAST.
HOWEVER... NORTHWEST FLOW ALOFT WILL BRING ANOTHER DISTURBANCE INTO
OUR AREA SATURDAY NIGHT... WITH ANOTHER BLAST OF COLD AIR
ARRIVING. OMEGA FIELDS SHOW EVIDENCE OF WEAK UPWARD FORCING
ASSOCIATED WITH THE DISTURBANCE TO PRODUCE ANOTHER ROUND OF -SN
ACROSS PORTIONS OF THE AREA. HOWEVER... ISENTROPHIC FIELDS AT THIS
TIME ARE NOT VERY IMPRESSIVE... AND SHOW STRONG DOWNGLIDE BY 12Z
SUNDAY. GFS BRINGS THE PRECIPITATION FURTHER SOUTH INTO OUR
AREA... WHILE ECMWF KEEPS IT ACROSS OUR NORTH. AS A RESULT...
SLIGHTLY HIGHER POPS ARE ACROSS NORTHERN OKLAHOMA FOR SUNDAY.

.DISCUSSION...
UPPER LOW OVER SOUTHERN NM/NORTHERN OLD MEXICO WILL MOVE EAST
ACROSS THE SOUTHERN PLAINS TONIGHT AND FRIDAY. THIS SYSTEM HAS
BROUGHT MID-LEVEL CLOUDS TO PARTS OF THE FA WHICH ARE EXPECTED TO
PERSIST OVERNIGHT INTO FRIDAY. WITH THE CLOUD COVER TEMPERATURES
TONIGHT WILL REMAIN SLIGHTLY WARMER THAN LAST NIGHT IN MANY
LOCATIONS. HOWEVER... WILL STILL BE COLD WITH LOWS RANGING FROM
AROUND ZERO IN THE NORTH TO THE LOW TEENS ALONG THE RED RIVER. THE
UPPER LOW WILL ALSO BRING A CHANCE OF LIGHT SNOW OR SNOW FLURRIES
TO APPROXIMATELY THE SOUTHEAST HALF OF THE FA BY FRIDAY. SOME
ACCUMULATIONS WILL BE POSSIBLE. HOWEVER... THESE ARE NOT EXPECTED
TO BE LARGE WITH THE GREATEST AMOUNTS... MAYBE UP TO AN INCH...
EXPECTED IN SE PORTIONS OF THE FA. TEMPERATURES WILL CONT TO
GRADUALLY WARM FRIDAY AND SATURDAY WITH MOST PLACES EXPECTED TO
CLIMB ABOVE FREEZING SATURDAY.

NW FLOW ALOFT WILL AFFECT THE SOUTHERN PLAINS THIS WEEKEND INTO 
EARLY NEXT WEEK. MODELS SHOW SEVERAL DISTURBANCES THAT WILL MOVE 
THROUGH THIS FLOW... BRINGING SEVERAL CHANCES FOR LIGHT SNOW/SNOW 
FLURRIES SAT NIGHT THROUGH SUNDAY NIGHT. SNOW ACCUMULATIONS OF AN 
INCH OR TWO WILL BE POSSIBLE IN SOME LOCATIONS BY MONDAY BUT NO 
SIGNIFICANT PRECIP IS EXPECTED. A COLD FRONT WILL ALSO MOVE ACROSS 
THE REGION SUNDAY BRINGING ANOTHER ROUND OF COLD AIR THAT WILL 
CONTINUE INTO THE MIDDLE OF NEXT WEEK.

MORE SIGNIFICANT WINTER PRECIPITATION MAY BE POSSIBLE TUESDAY AND 
WEDNESDAY. MODELS SHOW A SHORTWAVE MOVING SE TOWARDS THE SOUTHERN 
PLAINS TUESDAY THEN MOVING ACROSS THE REGION WEDNESDAY. RIGHT NOW 
THIS SYSTEM DOES NOT LOOK AS STRONG AS THE ONE FROM EARLIER THIS 
WEEK. HOWEVER... THE SYSTEM COULD STILL PRODUCE SEVERAL INCHES OF 
SNOW IN SOME LOCATIONS ALONG WITH GUSTY WINDS AND COLD WIND CHILLS. 
BEING SIX TO SEVEN DAYS AWAY MANY THINGS CAN CHANGE BUT RIGHT NOW 
TUESDAY AND WEDNESDAY LOOKS LIKE THE NEXT CHANCE FOR IMPACTFUL SNOW 
ACCUMULATIONS IN PARTS OF THE FA.

.DISCUSSION...
TOUGH CALL ON HEADLINES IN SE OK THIS MORNING. SNOW LIKELY TO BE
LIGHT AND POWDERY AND WIND WILL HAVE MINIMAL EFFECT AS FAR AS ANY
BLOWING. BUT THERE IS ENOUGH CONCERN REGARDING THE INTENSITY AND
TRACK OF THE UPPER LOW OVER TX... AND EXPECTED HIGH SNOW-TO-WATER
RATIOS IMPROVE THE CHANCES OF AT LEAST SOME LOCAL 2-3 INCH
AMOUNTS. WE WILL ISSUE AND ADVISORY THROUGH 22Z FOR A FEW ZONES IN
SE AND FAR SCENTRAL OK. SNOW SHOULD TAPER OFF AND END BY THIS EVENING.

LEANING TOWARD THE COOL SIDE OF GUIDANCE TEMPS NEXT COUPLE DAYS...
AT LEAST WHERE THERE IS SNOW COVER. THIS MEANS HIGHS MUCH LOWER
THAN THE NAM-BASED MET GUIDANCE. INTERESTING THAT THE NAM12 SFC-T
FIELDS CAPTURE THE SNOW FIELD AND KEEP MOST OF IT IN THE LOW 30S
OR LESS EACH DAY THROUGH MONDAY... BUT THE MET HAS OKC UP TO 48
SATURDAY. KEEPING MOST OF THE SNOW AREAS IN THE 30S EVEN INTO
SATURDAY BUT AT LEAST MOST AREAS FINALLY SHOULD CREEP ABOVE
FREEZING FOR A WHILE.

SYSTEM SWINGING QUICKLY THROUGH FROM THE NW SAT NIGHT AND SUPER
BOWL SUNDAY NEEDS TO BE WATCHED FOR ADDITIONAL ACCUMULATIONS.
HEAVY AMOUNTS APPEAR UNLIKELY GIVEN UNFAVORABLE LOW-LEVEL WINDS
AND GENERAL LACK OF MOISTURE... BUT MODELS SUPPORT A BAND/SWATH OF
AT LEAST LIGHT SNOW STREAKING ESE ACROSS MAINLY CENTRAL/S OK. GFS
NOW DROPS 4-7 INCHES OVER SW OK. POPS HAVE BEEN INCREASED OVER
MOST OF THE AREA BUT FOR NOW ARE BEING HELD IN THE 30-40 RANGE.  

YET ANOTHER SYSTEM DROPS SE TOWARD THE AREA TUE-WED COINCIDING
WITH YET ANOTHER ARCTIC AIR MASS INVADING THE AREA. MIDWEEK
TEMPERATURES HAVE BEEN LOWERED FROM THE LATEST GFS-MOS GUIDANCE -
CONSIDERABLY IN SOME CASES. ECMWF AND GFS AGREE ON THE ARCTIC
INTRUSION COMMENCING ON TUESDAY AND GOING INTO FULL GEAR BY
TUESDAY NIGHT WITH MORE STRONG WINDS AND BRUTAL WIND CHILLS... AND
PROBABLY MORE SNOW AND BLOWING SNOW.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
328 PM CST FRI FEB 4 2011

.DISCUSSION...THERE IS MUCH INTEREST IN WHAT WILL BE A CONTINUED 
COLD PATTERN FOR THE NEXT WEEK...WITH AT LEAST TWO MORE 
OPPORTUNITIES FOR SNOW.

AN UPPER LOW TRACKING THROUGH OKLAHOMA AND NORTH TEXAS TODAY...HAD 
LITTLE OPPORTUNITY TO AMPLIFY...GIVEN THAT IT WAS OVERRIDING A 
STABLE COLD DOME. BUT THE BROAD LARGE SCALE ASCENT...COUPLED WITH 
VERY COLD UPPER LEVEL TEMPERATURES...RESULTED IN A DENDRITIC SNOW 
GROWTH PROCESS...AND GENEROUS SNOWFALL OF 1-3 INCHES NEAR INTERSTATE 
35...AND 3-5 INCHES FARTHER EAST. THE LOW WAS SLOW MOVING...WITHOUT 
A REAL KICKER SYSTEM. IT WAS OPENING UP...THOUGH...AND WHATEVER SNOW 
FALLS THIS EVENING SHOULD BE LIGHTER AND LIGHTER...WITH LITTLE 
ADDITIONAL ACCUMULATION.

FLOW WILL THEN RESPOND TO AN APPROACHING DIP IN THE NORTHERN JET 
STREAM. INCREASED WESTERLY FLOW AT ALL LEVELS SHOULD YIELD CLEARING 
OVERNIGHT. WITH DRY AIR ADVECTING OVER THE SNOW FIELD IN A DOWNSLOPE 
FASHION...SUSPECT THERE WILL NOT BE ANY SIGNIFICANT FOG...THOUGH 
PATCHY SHALLOW FOG DUE TO MELTING/SUBLIMATION IS POSSIBLE. MID LEVEL 
CLOUDS WILL INCREASE ON SATURDAY...BUT SKIES SHOULD BE AT LEAST 
PARTLY SUNNY...WITH TEMPERATURES FORECAST ABOVE FREEZING FOR AT 
LEAST A FEW MIDDAY HOURS.

THE NORTHERN STREAM CLIPPER SYSTEM THEN ARRIVES SATURDAY NIGHT AND 
SUNDAY. IT HAS BEEN DIFFICULT TO EXTRACT THE MOST PERSISTENT AND 
MEANINGFUL SIGNALS FROM THE MODELS REGARDING THIS SYSTEM. OUR 
TAKE...HOWEVER...IS THAT WHATEVER LOW LEVEL WARMING TAKES PLACE 
SATURDAY SHOULD BE QUICKLY REDUCED BY POST FRONTAL LIFT AND 
EVAPORATIVE COOLING ASSOCIATED WITH THE CLIPPER SYSTEM. WE SHOULD 
EXPERIENCE A MINIMAL PERIOD OF COLD LIGHT RAIN THAT WILL CHANGE 
QUICKLY OVER TO SNOW. QPF IN THE NAM HAS BEEN LIGHT OR AT LEAST 
INCONSISTENT...AS THE 18Z RUN NOW PAINTS A THIN STRIPE OF 1-3 
INCHES. THE PATTERN OF HEIGHT FALLS...STEEP MID LEVEL LAPSE 
RATES...AND LIFT IN THE DENDRITIC CRYSTAL ZONE...ARGUES TOWARD A 
MORE WIDESPREAD ACCUMULATION OF SNOW THAT MAY AFFECT MOST IF NOT ALL 
OF OUR FORECAST AREA. MAXIMUM AMOUNTS WOULD BE LOCATED NEAR THE 
TRACK OF GREATER HEIGHT FALLS THROUGH WESTERN AND SOUTHERN OKLAHOMA 
AND WESTERN NORTH TEXAS. WITH SUPPORT OF THE ECMWF AND GFS...WE 
BUMPED SNOW GRIDS UP TO REFLECT 1-3 INCHES ACROSS THE REGION. WITH 
SNOW TO LIQUID RATIOS LIKELY TO BE NEAR OR GREATER THAN AVERAGE...WE 
WOULD NOT BE SURPRISED TO SEE LOCAL REPORTS OF 4 TO 5 INCHES MUCH 
LIKE WE RECEIVED TODAY. SINCE THIS IS NOT UNTIL THE THIRD AND FOURTH 
PERIODS...AND GIVEN SOME LACK OF MODEL CONVERGENCE...WE WILL NOT 
ISSUE AN ADVISORY JUST YET...BUT SUSPECT ONE WILL BE NEEDED. 
FORTUNATELY...WINDS SHOULD NOT BE TOO STRONG WITH THIS SYSTEM...BUT 
GUSTS OVER 20 MPH ARE LIKELY.

AFTER A BRIEF AND LIMITED WARM UP ON MONDAY...WE SEE ANOTHER WEATHER 
SYSTEM TAKE SHAPE TUESDAY AND WEDNESDAY. UNLIKE THE CLIPPER 
SYSTEM...THIS ONE COMES IN AT A FLATTER ANGLE...AND HAS MORE 
POTENTIAL TO UNDERGO AMPLIFICATION. THE DEGREE OF AMPLIFICATION WILL 
DEPEND ON THE TIMING OF THE NEXT ARCTIC COLD FRONT ALONG WITH THE 
STRENGTH OF THE UPPER WAVE...SOMETHING THAT WILL NOT BE SAMPLED BY 
THE INLAND UPPER AIR NETWORK UNTIL MONDAY MORNING. THEREFORE...THERE 
IS A LARGER AMOUNT OF UNCERTAINTY REGARDING THIS SYSTEM. WE ARE 
CONFIDENT...HOWEVER...THAT THE SYSTEM WILL BRING VERY COLD WEATHER 
AND INCREASED WINDS BY WEDNESDAY...AND THAT SOME SNOW ACCUMULATION 
IS LIKELY OVER PART OR MOST OF THE REGION. THE 12Z GFS REPRESENTS ONE 
EXTREME...WITH A VERY EARLY ARRIVAL OF COLD AIR AND LITTLE 
AMPLIFICATION OF THE UPPER WAVE...WHILE THE 12Z ECMWF REPRESENTS 
ANOTHER EXTREME...WITH THE SURFACE AND UPPER FEATURES ACTING IN 
CONCERT TO GENERATE A STRONG WINTER STORM. WITH THE GFS TENDENCY TO 
MOVE SYSTEMS TOO QUICKLY...WE LEANED CLOSER TO THE ECMWF IN 
SPREADING HIGH CHANCE POPS AND GREATER WIND SPEEDS INTO WEDNESDAY. 
FOLLOWING THE ARCTIC FRONT...REGARDLESS OF THE INTENSITY OF 
SNOWFALL...THE COLD AIR IS LIKELY REMAIN IN PLACE THROUGH THE END OF 
NEXT WEEK. AGAIN...THE STORM MAY COME INTO BETTER FOCUS OVER THIS 
WEEKEND...BUT CERTAINLY BY MONDAY...AS THE UPPER TROUGH MOVES INLAND.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
424 AM CST SAT FEB 5 2011

.DISCUSSION...
DOWNSLOPE FLOW AND LACK OF SNOW COVER SHOULD ALLOW NW AND FAR W OK
TO WARM UP TODAY. ELSEWHERE IT WILL BE A STRUGGLE BECAUSE OF THE
SNOW... BUT MOST AREAS SHOULD GET ABOVE FREEZING FOR THE FIRST
TIME SINCE MONDAY OR MONDAY NIGHT. 

CLOUDS INCREASING TODAY AND TONIGHT AHEAD OF NEXT SYSTEM
APPROACHING FROM THE NW. ASSOCIATED COLD FRONT MOVES THROUGH
TONIGHT WITH LITTLE MORE THAN A WIND SHIFT... BUT THE UPPER SYSTEM
STILL COULD LAY OUT A STREAK OF LIGHT PRECIP TONIGHT INTO
SUNDAY... MOST LIKELY AFFECTING NW/NCENTRAL TX AND S OK. NEW NAM
HAS A NARROW BAND OF 1-3 INCH SNOW CENTERED NEAR THE RED RIVER
FROM LATE TONIGHT THROUGH EARLY EVENING SUNDAY. GFS HAS A SIMILAR
BAND WHILE ECMWF KEEPS HIGHEST TOTALS OVER HIGHER TERRAIN OF
NM/WTX. ECMWF SCENARIO COULD BE RIGHT CONSIDERING THERE IS STILL
SOME QUESTION OF PRECIP TYPE DURING AT LEAST PART OF THE EVENT.
ALL IN ALL THIS LOOKS MOST LIKELY TO BE ANOTHER ADVISORY-TYPE
EVENT... BUT BECAUSE OF UNCERTAINTIES ON HOW FAR N-S THE
ACCUMULATION BAND WILL END UP WE WILL FOLLOW THE GUIDANCE TRENDS
AND BRING POPS BACK DOWN INTO THE HIGH-CHANCE RANGE. THIS ONE IS
LIKELY TO HAVE SOME EFFECT ON TRAVEL CONDITIONS FOR THOSE HEADING
DOWN TO THE SUPER BOWL FROM THE N ON SUNDAY.

THE NEXT SYSTEM DUE IN AROUND TUE-WED HAS THE POTENTIAL TO BE
MORE TROUBLESOME. ARCTIC HIGH IS POISED OVER NW CANADA TO DELIVER
ANOTHER SHOT OF UNSEASONABLY COLD AIR TO THE REGION BEGINNING TUE.
MODELS NOW IN BETTER AGREEMENT ON TIMING OF NEXT UPPER TROUGH.
PRECIP MAY START MON NIGHT N... BUT MORE LIKELY TO START TUE IN
MOST AREAS BEFORE PEAKING TUE NIGHT AND TAPERING OFF WED. THIS ONE
LIKELY TO FEATURE MORE WIND... MORE SNOW... AND COLDER AIR THAN
THE ONE TONIGHT/SUNDAY. THIS COULD BE ANOTHER RELATIVELY HIGH-
IMPACT EVENT. LATEST ECMWF HAS SFC WINDS 15-25KT ALL AREAS AND
6-10 INCHES OF SNOW OVER MUCH OF OK WITH SFC TEMPS INTO THE SINGLE
DIGITS BY WED. NEW GFS NOT AS BAD IN TERMS OF SNOW AND COLD BUT
STILL HAS 6+ INCHES OVER E OK AND TEMPS IN THE TEENS ENTIRE AREA.
WOULD ANTICIPATE A LOT OF MODEL-TO-MODEL AND RUN-TO-RUN CHANGES
NEXT SEVERAL DAYS. WE WILL NEED TO KEEP A CLOSE EYE ON THIS ONE.

COLDEST AIR SETTLES OVER THE AREA ALONG WITH THE SFC HIGH WED
NIGHT AND THU. AFTER THAT THERE ARE ACTUAL SIGNS THAT THE
E-PACIFIC UPPER HIGH/RIDGE... AND THUS THIS MISERABLE PATTERN...
WILL BREAK DOWN LATE NEXT WEEK. THIS EVENTUALLY WOULD ALLOW
TEMPERATURES TO RETURN TO NEAR OR EVEN ABOVE CLIMATOLOGY BY NEXT
WEEKEND.

308 PM CST SAT FEB 5 2011

.DISCUSSION...
OBSERVATIONS CLEARLY INDICATE THAT SIGNIFICANT MODIFICATIONS HAVE
OCCURRED OVER THE REGION THE PAST 24 HOURS. U/A DATA SHOWS THAT
WE HAVE WARMED SOME 15C IN LOWER LEVELS OF ATMOSPHERE. WITH
INCOMING AIRMASS NOT ALL THAT COLD...WE MAY HAVE TROUBLE WITH
CONVERSION OF RAIN TO SNOW LATE TONIGHT AND TOMORROW
MORNING...WHEN LIFT IS AT ITS BEST. THE EXCEPTION WILL BE ANY
HEAVY BANDS OF PRECIPITATION WHERE MELTING EFFECTS WILL ALLOW
ENOUGH COOLING FOR ACCUMULATING SNOWS. COLD AIR SHOULD BECOME
DEEP ENOUGH TOWARD AND AFTER NOON TOMORROW FOR ALL SNOW...BUT THE
LIFT AND AMOUNT/INTENSITY OF PRECIPITATION WILL BE ON A DOWNWARD
TREND.

MANY FLIES IN THE OINTMENT HOWEVER. THERE ARE A LOT OF VARIABLES
TO ACCOUNT FOR LOWS TONIGHT AND PRECIP TYPE AND TEMPS TOMORROW. WE
HAVE THE REMAINING SNOW COVER. IMPRESSIVE DOWNSLOPE WARMING MOST
AREAS. INCREASING/THICKENING CLOUD COVER WHICH WILL MINIMIZE COOLING
TONIGHT. ALTHOUGH TEMPS WILL GET COLDER WHERE WE HAVE THE
REMAINING SNOW COVER...WE WILL WARM THE OVERNIGHT LOWS CLOSE TO
OR SLIGHTLY WARMER THAN GUIDANCE VALUES. WITH THAT BEING TYPED...WE
CANNOT ABSOLUTELY RULE OUT FREEZING DRIZZLE OR FREEZING RAIN OVER
SNOWPACK LATE TONIGHT AND EARLY TOMORROW MORNING. WITH MUCH...MUCH
HIGHER DEWPOINTS OWED TO EROSION OF SNOWPACK...AND MOST OF THEM
ARE NOW WARMER THAN THE MID-UPR 20S...WE ARE HEDGING SURFACE/BLYR
WET BULBS WILL STAY AOA FREEZING.

BRIEF WARM UP AGAIN AHEAD OF TUESDAY/WEDNESDAY STORM SYSTEM.
ALTHOUGH THIS APPEARS TO BE ANOTHER VERY COLD AND WINDY SYSTEM...WE
DO NOT SEE ANY SIGNS THAT THIS EVENT WILL BE AS STRONG AS LAST
WEEKS BLIZZARD.

NATIONAL WEATHER SERVICE NORMAN OK
500 AM CST SUN FEB 6 2011

.DISCUSSION...
FOCUS TODAY IS ON THE S HALF OF THE AREA... S OF I-40... WHERE
PRECIP IS INCREASING AND MESONET METEOGRAMS SHOW TENDENCIES
SUGGESTIVE OF HEAT BURSTS. SFC COLD FRONT FINALLY MOVING S THROUGH
CENTRAL OK AND INTO NCENTRAL TX. GRADUAL COOLING MAY CHANGE PRECIP
OVER TO SNOW... BUT MUCH OF IT THIS MORNING MAY FALL AS RAIN OR A
RAIN/SLEET MIX WHERE HIGHER REFLECTIVITIES ARE BEGINNING TO
APPEAR. AT THIS TIME THIS STILL LOOKS LIKE A LOW-END EVENT WITH
PERHAPS AN INCH OR 2 OF SNOW OR SLEET/SNOW ACCUMULATIONS IN SOME
AREAS. NO HEADLINES ARE ANTICIPATED BUT WE OF COURSE WILL CONTINUE
TO MONITOR. ANY LINGERING PRECIP SHOULD BE OUT OF OUR SE ZONES BY
EARLY-MID EVENING.

MORE TROUBLE BREWING LATER IN THE WEEK AS ALL INDICATIONS POINT TO
ANOTHER SIGNIFICANT COLD INTRUSION AND ANOTHER PROBABLE HIGHER-END
WINTER STORM TUE INTO WED. 1042-MB SFC HIGH IS POISED OVER CANADA
TO MOVE S. THIS AIR WILL ARRIVE IN N/NW OK EARLY TUE MORNING
FOLLOWED BY FALLING DAYTIME TEMPS AND INCREASING N-NE WINDS BEHIND
THE ARCTIC FRONT AS IT MOVES INTO CENTRAL/SW OK BY EARLY EVENING
AND THROUGH THE REST OF THE AREA BY 12Z WED. BY THAT TIME WIND
CHILLS LIKELY TO BE BACK DOWN INTO THE -5 TO -20 RANGE N AND NW OF
THE FRONT.

SNOW MAY BEGIN IN NW OK TUE AFTERNOON BUT THE MAIN EVENT APPEARS
LIKELY TO BE TUE NIGHT INTO WED. WE CREATED SOME 6-H SNOW ACCUM
GRIDS BASED ROUGHLY ON MODEL SNOWFALL CONSENSUS AND FORECAST
QPF... WHICH YIELD WIDESPREAD 6-10 INCH STORM TOTALS ACROSS MOST
OF N AND CENTRAL OK BY WED EVENING. STANDARD DISCLAIMERS WILL
APPLY DUE TO PROBABLE VARIANCE IN THE MODEL FORECASTS OF THE TRACK
AND SPEED OF THE SYSTEM. REGARDLESS OF THE WHERE AND HOW-MUCH
ASPECTS OF THE SNOW... BLOWING/DRIFTING AND DANGEROUS COLD ARE
ALMOST CERTAIN TUE NIGHT AND WED. WINDS DO NOT LOOK AS STRONG WITH
THIS ONE SO ANOTHER BLIZZARD LIKE LAST WEEK IS UNLIKELY... BUT THE
IMPACT IS LIKELY TO BE SIGNIFICANT NONETHELESS. 

LONGWAVE PATTERN DEAMPLIFIES AFTER THE TUE-WED STORM AND THE EAST-
PACIFIC RIDGE FINALLY GETS HAMMERED DOWN BY NEXT WEEKEND. PATTERN
SUPPORTS A DRY AND WARMER REGIME BY END OF NEXT WEEK... ALTHOUGH
RESIDUAL SNOW COVER AND THE RENOWNED STUBBORNNESS OF THESE ARCTIC
AIR MASSES TO LET GO WILL LIKELY SLOW THE WARMING.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
310 PM CST SUN FEB 6 2011

.DISCUSSION...MAIN FOCUS IS ON THE MID WEEK WINTER STORM POTENTIAL. 
THERE ARE...HOWEVER...SHORT TERM ISSUES AS WELL. A VERY GRADUAL 
DIGGING OF COLD AIR INTO THE BASE OF AN UPPER TROUGH...HAS RESULTED 
IN WEAK CYCLOGENESIS ALONG A SURFACE FRONT IN NORTHEAST TEXAS TODAY. 
A BROAD BUT SOMEWHAT BROKEN FRONTAL BAND OF LIGHT RAIN EXISTS NORTH 
OF THE FRONT. MODELS FORECAST LIFTING TO PERSIST THROUGH THE 
EVENING...MAINLY FROM WICHITA FALLS TO SEMINOLE AND EASTWARD. WEAK 
LOW LEVEL HEATING DURING THE DAY HAS KEPT THE PRECIPITATION AS 
RAIN...BUT COLD ADVECTION AT 925-850 MB...COUPLED WITH SURFACE 
COOLING...MAY ALLOW SOME SNOW TO THE GROUND THIS EVENING. WE DO NOT 
EXPECT MUCH ACCUMULATION...IF ANY.

WHILE THE PRIMARY FRONT WAS IN NORTH TEXAS...A SECOND...BACKDOOR 
ARCTIC...FRONT...WAS APPROACHING THROUGH KANSAS. ON MONDAY THIS 
FRONT WILL SEPARATE SOMEWHAT MILD AIR IN OUR SOUTHWEST ZONES FROM 
CHILLY AIR TO THE NORTH AND EAST. THIS WILL ALSO SERVE AS A FOCUS 
FOR FRONTOGENESIS WHEN THE MID WEEK SYSTEM BEGINS TO APPROACH ON 
TUESDAY. WE THEREFORE ADDED A MENTION OF FREEZING DRIZZLE TO THE 
GRIDS LATE MONDAY NIGHT THROUGH TUESDAY...AS THE FRONTAL ZONE 
MOISTENS UP...BUT BEFORE LIFT BECOMES DEEP ENOUGH TO SUPPORT SNOW.

REGARDING THE POTENTIAL WINTER STORM...WE STRONGLY CONSIDERED A 
WINTER STORM WATCH ON THIS SHIFT...BUT THROUGH COLLABORATION WITH 
SURROUNDING OFFICES...CHOSE TO DEFER TO THE NEXT SHIFT. MODELS ARE 
CONSISTENT IN THE SWATH OF HEAVIEST SNOW BEING ACROSS THE MAIN BODY 
OF OKLAHOMA...WITH LESSER AMOUNTS INTO TEXAS. THERE IS STILL SOME 
QUESTION...THOUGH...AND RUN TO RUN INCONSISTENCY...AS TO THE TIMING 
OF INITIAL ONSET AND THE DEGREE TO WHICH THE FRONTAL WAVE AMPLIFIES 
TUESDAY NIGHT AND WEDNESDAY. THE SNOWFALL AMOUNTS IN THE SREF MEAN 
ARE LIGHTER THAN THE OPERATIONAL MODELS...THOUGH STILL SUPPORTIVE OF 
WINTER STORM CRITERIA...ESPECIALLY GIVEN THE GUSTY WINDS AND LOW WIND 
CHILLS EXPECTED. WE TENDED TO LIKE THE SREF MEAN SNOWFALL...ROUGHLY 
3-6 INCHES...AS THIS SYSTEM DOES NOT YET SHOW ANYTHING BUT AN OPEN 
TROUGH AT 700 MB...AND IS PROGRESSIVE IN NORTHWESTERLY FLOW...RATHER 
THAN TURNING THE CORNER AND UNDERGOING CYCLOGENESIS IN SOUTHWESTERLY 
FLOW...WHICH WOULD UNDOUBTEDLY LEAD TO HEAVIER SNOWFALL. GIVEN THAT 
THE PERIODS OF INTEREST ARE JUST BEYOND 48 HOURS...WE WILL LET THE 
UPPER SYSTEM COME INTO THE UPPER AIR NETWORK THIS EVENING...LETTING 
THE NIGHT SHIFT TAKE A LOOK AT MODEL TRENDS BEFORE PUTTING OUT WHAT 
WE WOULD THINK SHOULD BE A FAIRLY LIBERAL WINTER STORM WATCH.

.UPDATE...
PRECIPITATION CONTINUES TO DIMINISH ACROSS THE SOUTHERN PART OF THE
FORECAST AREA THIS EVENING. TEMPERATURES HAVE REMAINED WARM ENOUGH
FOR LIQUID PRECIPITATION... ALTHOUGH A CHANGE TO LIGHT
SNOW/FLURRIES STILL LOOKS POSSIBLE AS THE TEMPERATURES COOL. HAVE
ADJUSTED THE WEATHER GRIDS TO KEEP MORE LIQUID PRECIPITATION LATE
THIS EVENING BUT STILL MAINTAINING A MIX. MID-LEVEL CLOUDS ACROSS
MUCH OF THE AREA HAVE KEPT TEMPERATURES RELATIVELY WARM. MIN
TEMPERATURES OVERNIGHT MAY STAY HIGHER THAN CURRENT FORECAST BUT
WITH SOME CLEARING MOVING INTO THE NORTHWEST PORTION OF THE AREA
MAY STILL MAKE THE FORECAST MINS LATE... ALTHOUGH HAVE ADJUSTED
HOURLY TEMPERATURE GRIDS TO SLOW THE COOLING DOWN OVERNIGHT.

WENT AHEAD AND ISSUED THE WINTER STORM WATCH FOR TUESDAY NIGHT AND
WEDNESDAY AT THE BEGINNING OF THE SHIFT AS THERE HAS BEEN A
SOMEWHAT PERSISTENT SIGNAL FOR AT LEAST THE POTENTIAL OF 4+
INCHES OF SNOW SOMEWHERE OVER THE FORECAST AREA. AS ALWAYS THERE
IS STILL SOME UNCERTAINTY IN THE EXACT STORM PATH... BUT
CONFIDENCE IS SUFFICIENT FOR A WATCH AT THIS STAGE. 00Z NAM
ISENTROPIC ANALYSIS IN THE 285K THROUGH 295K LAYERS SHOWS A GOOD
FETCH OF MOISTURE FROM THE SOUTH LIFTING OVER THE FRONTAL ZONE ON

.DISCUSSION...
MAIN FOCUS THIS MORNING HAS BEEN ON FINE-TUNING THE QPF AND SNOW
ACCUMULATION GRIDS TUE-WED - TO THE EXTENT POSSIBLE AS WE ARE
STILL ROUGHLY 48 HRS FROM THE TIME OF MOST RAPIDLY-DETERIORATING
CONDITIONS. FURTHER CHANGES ARE LIKELY... BUT FOR NOW WE ARE STILL
COMING UP WITH WIDESPREAD 4-10 INCH TOTALS ACROSS THE NORTHERN 3/4
OF THE AREA. DISCREPANCIES CONTINUE BETWEEN MODELS WITH 06Z NAM
RUNNING A SWATH OF 10-15 INCHES ACROSS OUR N ZONES WHILE ECMWF AND
GFS HAVE 4+ TOTALS SPREADING FARTHER S INTO N TX. WE WILL LET THE
EXISTING WINTER STORM WATCH RIDE AT THIS TIME. AN EXTENSION
FARTHER S MAY BE NEEDED LATER... BUT CURRENT INDICATIONS ARE THAT
THE WORST OF IT WILL HOLD OFF UNTIL 5TH PERIOD/WEDNESDAY FOR AREAS
NOT ALREADY IN THE WATCH.

LOW-LEVEL WARM ADVECTION AND NORTHWARD MOISTURE TRANSPORT WILL BE
WELL UNDERWAY BY TUE MORNING COURTESY OF 50-KT LLJ. LIGHT PRECIP
MAY BREAK OUT AS EARLY AS MON NIGHT IN FAR N OK... ALTHOUGH MORE
LIKELY TO BE FARTHER N IN AREA OF INCREASING UPSLOPE FLOW AND LOW-
LEVEL MOISTURE CONVERGENCE OVER CENTRAL PLAINS. MAIN EVENT COULD
BEGIN LATE TUE IN NW OK... BUT TUE NIGHT WILL BE WHEN MOST AREAS
SEE SIGNIFICANT AND POSSIBLY RAPID DETERIORATION OF CONDITIONS.
STRONG INCREASE IN SFC THERMAL GRADIENT WITH THE ARCTIC FRONT TUE
NIGHT BEARS TESTIMONY TO THE STRENGTH OF THE LOW-LEVEL
FRONTOGENETIC FORCING TAKING PLACE. PRECIP INCREASING AND
SPREADING SE WITH/BEHIND SFC FRONT WHILE N WINDS INCREASE. POPS
ARE INCREASED TO CATEGORICAL ALL AREAS TUE NIGHT. THERE MAY BE A
RELATIVELY-BRIEF PERIOD OF WINTRY MIX NEAR THE FRONTAL ZONE TUE
NIGHT BEFORE A QUICK TRANSITION TO SNOW AND BLOWING SNOW. AFTER
ANOTHER MAJOR MESS WED MORNING OVER MUCH OF THE AREA... PRECIP
SHOULD SHUT DOWN FROM W TO E DURING THE DAY. MODEL QPFS ARE IN
GOOD AGREEMENT ON THIS TIMING. ARCTIC AIR WILL BE FLOODING INTO THE
AREA THE WHOLE TIME AND WILL SEND WIND CHILLS BACK DOWN BELOW ZERO
BY WED MORNING IN MOST AREAS. ONCE AGAIN WE WILL LIKELY END UP
WITH WIND CHILL ADVISORIES TO REPLACE ANY WARNINGS BY LATE WED.

NOTE THAT SFC WINDS WILL INCREASE DURING THE EVENT BUT DO NOT LOOK
AS STRONG AS THE ONE LAST WEEK. ALTHOUGH BLOWING AND DRIFTING WILL
BE CONSIDERABLE... AND IN FACT MAY BE WORSE THAN THE LAST ONE IF
SNOW AMOUNTS ARE HEAVIER... WE DO NOT ANTICIPATE BLIZZARD
CONDITIONS AT THIS TIME. 

DRY AND COLD WED-THU WITH WED NIGHT LIKELY TO BE THE COLDEST IN
TERMS OF ACTUAL TEMPERATURES. WE WILL FINALLY PUT AN END TO THIS
PATTERN THEREAFTER AS THE E-PAC RIDGE BREAKS DOWN AND THE FLOW
BECOMES ZONAL ACROSS THE CONUS. THIS NORMALLY WOULD LEAD TO A
QUICK AND SUBSTANTIAL WARMUP... BUT THE RESIDUAL SNOW COVER MAY
DELAY THE RETURN OF ABOVE-NORMAL TEMPS UNTIL LATE IN THE WEEKEND
OR EARLY NEXT WEEK. NEEDED TO IMPROVISE ON HIGH/LOW TEMPS FOR THIS
FORECAST AS GUIDANCE IS LIKELY WARMING US UP TOO MUCH TOO FAST.
TMAX/TMIN GRIDS BEYOND WED ARE A CONSENSUS BLEND OF ADJACENT GRIDS.

.DISCUSSION...MIDDAY UPGRADE TO WINTER STORM WARNING WAS BASED ON 
REMARKABLE MODEL CONSISTENCY REGARDING WARNING CRITERIA...4 TO 8 
INCH...SNOW AMOUNTS WITHIN THE BORDERS OF OKLAHOMA. GREATER 
UNCERTAINTY EXISTS TOWARD THE BORDERS...ESPECIALLY SOUTH INTO 
TEXAS...WHERE MID LEVEL ASCENT WILL BE OF SHORTER DURATION...AND 
MODEL SNOWFALL DROPS TO NEAR OR JUST BELOW WARNING CRITERIA OF 4 
INCHES. WITH TWO FORECAST CYCLES LEFT BEFORE THE ONSET OF SNOW IN 
OUR TEXAS COUNTIES...WE OPTED TO DEFER AN ADVISORY-VERSUS-WARNING
DECISION TO LATER SHIFTS.

IN OKLAHOMA...HOWEVER...IT LOOKS AS THOUGH THIS FRONTAL STORM 
SYSTEM...DESPITE REMAINING OPEN/ NOT DEVELOPING A CLOSED LOW/... 
WILL BE A VERY EFFICIENT SNOW PRODUCER. THE TEMPERATURE PROFILES ARE 
JUST SO FAVORABLE FOR MODERATE TO HEAVY SNOWFALL...GIVEN THAT THE 
COLD AIR IS ALREADY IN PLACE...AND WILL GET COLDER...PLACING A DEEP 
LAYER OF -10 TO -20 C AIR COINCIDENT WITH THE STRONGEST LIFT IN THE 
CLOUD LAYER. STEEP LAPSE RATES ABOVE 600 MB SHOULD ALSO ENHANCE SNOW 
GROWTH IN THE UPPER PART OF THE CLOUD...THUS SEEDING THE REST OF THE 
CLOUD WITH NUCLEI FOR GROWTH BY ACCRETION.

THE ECMWF HAS BEEN A MODEL OF CHOICE PRIMARILY FOR ITS HANDLING OF 
THE SURFACE COLD AIR AND INITIAL ONSET OF PRECIPITATION. THE 12Z GFS 
CAME IN VERY CLOSE TO THE ECMWF. THE NAM IS THE MOST NOTABLE OUTLIER 
IN THE SENSE THAT IT PROBABLY DOES NOT MOVE THE COLD AIR QUICKLY 
ENOUGH TUESDAY IN THE WAKE OF A NORTHERN STREAM WAVE. THE NAM ALSO 
INDUCES A STRONGER PRESSURE WAVE AT LOW LEVELS ALONG THE FRONT ON 
WEDNESDAY...WHICH RESULTS IN CYCLOGENESIS AND EVEN GREATER SNOWFALL 
THAN APPEARS IN OUR FORECAST. WHILE THE NAM AT LEAST REPRESENTS ONE 
POSSIBILITY WITHIN THE SPECTRUM...IT DOES NOT HAVE SUPPORT FROM 
OTHER GUIDANCE...AND DOES NOT APPEAR LIKELY...AS THE MID LEVEL 
FORCING SHOULD REMAIN LOCATED WELL NORTH OF THE FRONT.

WHILE WE LEFT THE GRIDDED FORECAST LARGELY INTACT FROM THE PREVIOUS 
SHIFT...THERE WERE A FEW CHANGES. WE INCREASED POPS TUESDAY AND 
ADDED MENTION OF FREEZING DRIZZLE IN THE NORTH...WHICH MAY EVEN 
BEGIN LATE TONIGHT. THE DRIZZLE WILL LIKELY OCCUR AS THE LOW LAYERS 
SATURATE WITHIN STRONG UPGLIDE...AND BEFORE MID LEVEL ASCENT IS 
SUFFICIENT TO GET SNOW GROWTH. MODELS...INCLUDING THE SREF...PLACE 
ACCUMULATING SNOW IN NORTHERN OKLAHOMA BY TUESDAY AFTERNOON...SO THE 
WINTER STORM WARNING BEGINS THERE AT 3 PM. AND WE EXTENDED THE END 
OF THE EVEN INTO WEDNESDAY EVENING OVER SOUTHEAST OKLAHOMA.

VERY LOW WIND CHILLS WILL DEVELOP DURING THE STORM...AND A WIND
CHILL ADVISORY MAY BE NEEDED AFTER THE WINTER STORM WARNING EXPIRES.
WINDS WILL AVERAGE 20 TO 25 MPH. SOME GUSTS TO 40 ARE LIKELY. NEAR
BLIZZARD CONDITIONS MAY EXIST WEDNESDAY MORNING. THE WINDS WILL
DECREASE MORE QUICKLY IN THE WAKE OF THIS SYSTEM...EVEN BY
WEDNESDAY AFTERNOON...COMPARED TO THE PREVIOUS WINTER STORM.

AFTER THIS STORM...THE LONG WAVE PATTERN TRANSITIONS TO ONE 
FEATURING LESS BLOCKING TO OUR EAST...AND A MORE PROGRESSIVE ZONAL 
FLOW THAT WILL FEATURE SOME MILDER WEATHER AT LEAST.

CLOUDS AND WIND WILL BOTH INCREASE OVERNIGHT BUT VFR CONDITIONS
WILL PREVAIL. CONDITIONS WILL BEGIN TO DETERIORATE AFTER 12Z AS
PRECIPITATION WITH THIS NEXT WINTER STORM BEGINS TO AFFECT THE
NORTHWEST OKLAHOMA TAFS. SURFACE LOW ALSO DEEPENS IN THE MORNING

WILL LOWER TO MVFR OR IFR WITH SOME LIFR CIGS POSSIBLE ESPECIALLY
AT KWWR AND KGAG. EXPECT TEMPERATURES TO COOL QUICKLY ENOUGH
TOMORROW TO SUPPORT A PERIOD OF FZRA AT THE NORTHERN AND WESTERN

.DISCUSSION...
TODAY WILL BE QUITE DIFFERENT FOR DIFFERENT PARTS OF OUR FORECAST
AREA. COLD EAST WINDS AND OCCASIONAL SNOW WILL BE TYPICAL IN THE
NORTH... WHILE OUR SOUTHERN COUNTIES WILL BE RELATIVELY MILD FOR
EARLY FEBRUARY.

THE COLD AIRMASS WILL EDGE SOUTH DURING THE DAY... BRINGING THE
SNOW WITH IT. AFTER SNOW BEGINS TO ACCUMULATE... THE MODERATE
NORTH TO NORTHEAST WINDS WILL START BLOWING IT AROUND. BY THIS
EVENING... RAIN AND SNOW WILL EXTEND AS FAR SOUTH AS I-40...
PERHAPS FARTHER.

THE PROVERBIAL WINTRY MIX IS LIKELY ACROSS OUR SOUTHERN COUNTIES
THIS EVENING... AND EVEN DURING THE NIGHT IN OUR FAR SOUTHEAST
COUNTIES. THIS WILL HOLD DOWN SNOWFALL ACCUMULATIONS SOMEWHAT IN
THOSE AREAS... BASICALLY THE SOUTHERN HALF OF OKLAHOMA... AND OUR
TEXAS COUNTIES.

AS THE STORM SYSTEM SHIFTS TOWARD THE EAST... ALL THE
PRECIPITATION WILL TURN TO SNOW... THEN END FROM WEST TO EAST
DURING THE DAY ON WEDNESDAY. COLD AIR WILL CONTINUE TO FLOW
SOUTH... AND TEMPERATURES WILL NOT RECOVER VERY MUCH DURING THE
DAY. VERY COLD OVERNIGHT LOWS ARE IN STORE FOR THE NEXT SEVERAL
NIGHTS.

AFTER THE STORM DEPARTS... THE FLOW WILL BECOME MORE WESTERLY...
SO WE WILL HAVE NOT ONLY MORE A MORE MODERATE AIRMASS BEING
BROUGHT EAST... BUT A DOWNSLOPE COMPONENT TO THE WINDS. ALL THIS
MEANS A STRONG WARM-UP... EXCEPT THAT THE SNOW ON THE GROUND WILL
COUNTER THE WARM-UP VERY SIGNIFICANTLY. BY SUNDAY... MOST OR ALL OF
THE SNOW SHOULD BE GONE... AND TEMPERATURES WILL BE CLOSER TO THE
SEASONAL NORMALS. A SLIGHT COOL-DOWN IS EXPECTED ON MONDAY... BUT
NOTHING LIKE TODAY/TONIGHT.

AFTER THE PRESENT WINTER STORM DEPARTS... NO FURTHER PRECIPITATION
IS EXPECTED THROUGH THE 7-DAY FORECAST PERIOD.

WITH THIS FORECAST ISSUANCE... WE WILL ISSUE A WINTER WEATHER
ADVISORY FOR KNOX AND BAYLOR COUNTIES IN TEXAS... AND UPGRADE THE
WINTER STORM WATCH IN OUR OTHER 6 TEXAS COUNTIES TO A WARNING.

PANHANDLES BORDER. SHOULD SEE THE SNOWFALL INTENSITIES RAMP UP 
ACROSS NORTHWEST AND WESTERN OKLAHOMA OVER THE NEXT SEVERAL HOURS. 
THE SWATH OF MODERATE TO HEAVY SNOWFALL WILL DEVELOP FURTHER EAST AS 
THE MAIN STORM SYSTEM SHIFTS FROM COLORADO OVER OKLAHOMA. THERE MAY 
BE A SHORT PERIOD OF SOME SLEET... AND MAYBE EVEN THUNDER SLEET 
ALONG A NARROW STRIP NEAR THE INTERSTATE 44 CORRIDOR PRIOR TO THE 
SWITCHOVER. EVEN WITH A PERIOD OF SLEET... MOST MODELS CONTINUE TO 
BE PRETTY CONSISTENT WITH WIDESPREAD 6+ INCHES OVER A LARGE PORTION 
OF OUR CWA... WITH SOME LOCATIONS OVER THE NORTHERN HALF OF OKLAHOMA 
PICKING UP CLOSE TO 10 INCHES. THE SNOW TOTALS OVER NORTHWEST 
OKLAHOMA WILL HAVE TO BE WATCHED... AS HI RESOLUTION MODELS SHOWING 
A PERIOD OF INTENSE SNOWFALL RATES AND SOMEWHAT HIGHER TOTALS. WE 
WILL GO AHEAD AND LEAVE CURRENT TOTALS AS IS FOR NOW... ADJUSTING AS 
NECESSARY THROUGH THE EVENING. 

THE OTHER ISSUE WITH THIS STORM IS THE VERY COLD TEMPERATURES THAT 
WILL OVERSPREAD THE AREA. MILD TEMPERATURES THIS AFTERNOON FROM 
INTERSTATE 40 SOUTH WILL BE KNOCKED DOWN 20 TO 30 DEGREES BY 
TOMORROW MORNING. VERY LITTLE RECOVERY WILL OCCUR TOMORROW AS 
WELL... WHICH WILL MAKE IT FEEL QUITE UNBEARABLE OUTSIDE. 

AS CONSISTENT AS THE MODELS HAVE BEEN WITH THIS WINTER STORM... THEY 
HAVE ALSO BEEN CONSISTENT IN ENDING THE HEAVIER PRECIPITATION ENDING 
FAIRLY QUICKLY FROM WEST TO EAST TOMORROW MORNING. GUSTY NORTHERLY 
WINDS WILL KEEP BLOWING AND DRIFTING SNOW THROUGH THE AFTERNOON. 

AFTER THE STORM MOVES EAST... A DRY FORECAST WILL DOMINATE THE 
EXTENDED... AS THE LARGE SCALE PATTERN SHIFT WILL BE IN FULL FORCE. 
WILL CONTINUE TO UNDERCUT GUIDANCE THROUGH SATURDAY DUE TO LINGERING 
SNOW COVER. AFTER THAT... TEMPERATURES SHOULD BE AT OR JUST ABOVE 
MID FEBRUARY AVERAGES.

.UPDATE...
PRIMARY PRECIPITATION BAND HAS SET UP FROM NORTH CENTRAL OKLAHOMA
SOUTHWEST INTO THE TEXAS PANHANDLE WITH THE PRECIPITATION
INCREASING SIGNIFICANTLY IN THE TEXAS PANHANDLE OVER THE LAST
COUPLE OF HOURS. IN THE NORTHERN OKLAHOMA BAND... SNOWFALL
ESTIMATES FROM LAW ENFORCEMENT INCLUDE 3 TO 4 INCHES AT BUFFALO...
4 TO 5 INCHES AT BLACKWELL AND AROUND 2 INCHES IN ENID SO FAR.
ALTHOUGH THE HEAVY SNOW EVENT IS ONGOING ACROSS THE NORTHERN TWO
TIERS OF COUNTIES IN OKLAHOMA... THE HEAVY SNOW BAND OVER THE
TEXAS PANHANDLE WILL MOVE EAST AND BECOME THE PRIMARY FEATURE OVER
WEST CENTRAL AND CENTRAL OKLAHOMA LATE THIS EVENING AND OVERNIGHT.

FARTHER SOUTHEAST... LIGHT RADAR REFLECTIVITIES HAVE CORRESPONDED
WITH SOME REPORTS OF LIGHT SNOW AND SLEET ACROSS CENTRAL AND
SOUTHERN OKLAHOMA. ALTHOUGH THE RADAR MAY BE OVERSHOOTING SOME OF
THE PRECIPITATION WITH FORCING AT SUCH LOW LEVELS.

HAVE MADE SOME RELATIVELY MINOR UPDATES TO THE PACKAGE THIS
EVENING... MAINLY TO UPDATE THE TIMING OF THE PRECIPITATION
/ESPECIALLY IN THE SOUTHEAST/... INCREASE WIND GUSTS /ESPECIALLY
IN THE SOUTHWEST/... AND REDUCE MIN TEMPERATURES IN MANY AREAS.
GIVEN THE SNOWFALL RATES AND EXPECTED EVOLUTION... THE PREDICTED
SNOWFALL AMOUNTS STILL LOOK REASONABLE. .26.

HEAVY SNOW CONTINUES TO AFFECT THE NORTHERN OK TAF SITES /KGAG..
KWWR AND KPNC/ WITH THE FIRST SNOW BAND. RADAR SHOWS SNOW
INCREASING ACROSS WEST CENTRAL OKLAHOMA NEAR KCSM AND KHBR AND
PERIODS OF HEAVY SNOW WILL BEGIN THERE SOON... AND PERSIST FOR A
FEW HOURS AS THE LARGE AREA OF HEAVY SNOW IN THE TEXAS PANHANDLE
MOVES EAST. THIS BAND WILL EVENTUALLY MOVE INTO KLAW.. KOKC AND
KOUN AND LIKELY KSPS DURING THE EARLY MORNING HOURS. LATEST MODELS
SUGGEST THAT THE SNOW WILL DIMINISH AT THE TAF SITES PRETTY

426 AM CST WED FEB 9 2011

.DISCUSSION...
WIDESPREAD SNOW... SOME OF IT QUITE HEAVY... IS OCCURRING OVER
NEARLY ALL OUR FORECAST AREA AT THIS TIME. MODERATE TO STRONG
NORTH WINDS ARE ALSO CAUSING BLOWING AND DRIFTING TO OCCUR.

WE EXPECT THE HEAVIEST BANDS OF SNOW... NOW OVER NORTHERN
OKLAHOMA... TO SHIFT EAST RATHER QUICKLY... AND SHOULD BE EXITING
OUR FORECAST AREA BY THE BEGINNING OF THE FIRST PERIOD OF THIS
FORECAST. AS A RESULT... THE HEAVIEST SNOWFALL EXPECTED THIS
MORNING... AFTER ABOUT 7 AM... WILL BE OVER OUR SOUTHEASTERN
COUNTIES. BLOWING/DRIFTING SNOW ARE EXPECTED TO CONTINUE... MAINLY
OVER THE SOUTHWEST QUADRANT OF OKLAHOMA... AND ADJACENT PARTS OF
WESTERN NORTH TEXAS... WHERE WINDS WILL CONTINUE TO BE STRONGEST.

THE SNOW SHOULD TAPER OFF QUICKLY AS THE DAY PROGRESSES... AND THE
LAST FLAKES SHOULD FALL OVER OUR FAR SOUTHEAST COUNTIES LATE THIS
AFTERNOON. NEW SNOW ACCUMULATIONS AFTER NOON WILL BE RELATIVELY
LIGHT... ALTHOUGH AN INCH OR TWO WILL STILL BE POSSIBLE OVER
SOUTH-CENTRAL AND SOUTHEAST OKLAHOMA.

TONIGHT WILL BE VERY COLD... WITH FRESH SNOW COVER... LIGHT
WINDS... AND GENERALLY CLEAR SKIES. LOW TEMPERATURES WILL DIP
BELOW ZERO OVER MUCH OF NORTHERN AND CENTRAL OKLAHOMA... AND
SINGLE DIGITS WILL BE THE RULE TO THE SOUTH.

THE EXTENSIVE... AND HEAVY... SNOW COVER WILL RESULT IN A VERY
FEEBLE TEMPERATURE RECOVERY TOMORROW... AND TOMORROW NIGHT WILL BE
COLD AGAIN... BUT NOT QUITE AS COLD.

THE LARGE-SCALE WEATHER PATTERN CHANGES SIGNIFICANTLY LATE THIS
WEEK AND NEXT WEEK. MUCH WARMER WEATHER WILL RETURN TO THE
SOUTHERN PLAINS. HOWEVER... ANY LINGERING SNOW COVER WILL GREATLY
LIMIT THE WARM-UP... AS SOLAR RADIATION WILL GO FIRST TO MELTING
SNOW... AND THEN EVAPORATING THE MOISTURE LEFT BEHIND.
NEVERTHELESS... ALONG THE FRINGES OF THE SNOW... RELATIVELY
UNMODIFIED WARM AIR WILL STILL BE ABLE TO RAISE TEMPERATURES
MARKEDLY. 

A FEW WEAK UPPER-LEVEL WAVES ARE FORECAST TO PASS OVER OKLAHOMA
AND NORTH TEXAS DURING THE LAST SEVERAL DAYS OF THE FORECAST...
BUT AT THIS TIME... IT APPEARS THAT MOISTURE WILL BE TOO LIMITED
TO WARRANT ANY MENTION OF RAIN CHANCES.

WE WILL NOT MAKE ANY CHANGES TO THE CURRENT WARNINGS AND
ADVISORY... HOWEVER... WE WOULD EXPECT THAT THE WARNING WILL BE
TERMINATED FROM WEST TO EAST DURING THE DAY... AND MAY BE REPLACED
WITH A WIND CHILL ADVISORY.

.DISCUSSION...THE SWATH OF HEAVIEST SNOWFALL THIS MORNING 
CONCENTRATED ALONG A BROAD MID LEVEL FRONT IN THE NORTHERN ONE THIRD 
OF OKLAHOMA. OTHER HEALTHY SNOWFALL TOTALS OF AT LEAST 4 INCHES WERE 
OBSERVED TO NEAR AND JUST SOUTH OF INTERSTATE 40...WITH GENERALLY 1 
TO 3 INCHES IN SOUTHERN OKLAHOMA AND NORTH TEXAS. A SUMMARY OF 
SNOWFALL OBSERVATIONS IS AVAILABLE AS A LOCAL STORM REPORT/LSR/ AND 
PUBLIC INFORMATION STATEMENT/PNS/ FROM OUR OFFICE...AS WELL AS IN 
GRAPHICAL FORMAT ON OUR WEB PAGE... WWW.SRH.NOAA.GOV/OUN/ENHANCED.PHP

THE STORM SYSTEM HAD LARGELY EXITED...ALTHOUGH COLD AIR CONTINUED TO 
SPILL SOUTHWARD INTO THE BASE OF A LARGE TROUGH NOW CARVED OUT OVER 
THE U.S. STREETS AFTERNOON STRATOCUMULUS AND SNOW FLURRIES WILL 
DIMINISH WITH NIGHTFALL. WIND SPEEDS WILL ALSO COME DOWN 
MARKEDLY...INTO THE 5-12 MPH RANGE...BUT WILL NOT RELAX ENTIRELY AS 
THERE IS NO WELL DEFINED HIGH PRESSURE CENTER TO SLIDE THROUGH THE 
REGION. WITH CLEAR SKIES AND TEMPERATURES FALLING TO THE SINGLE 
DIGITS ABOVE AND BELOW ZERO TONIGHT...WHAT LIGHT WIND THERE 
IS...WILL MAINTAIN WIND CHILL TEMPERATURES CLOSE ADVISORY CRITERIA 
IN SOME AREAS...AND SOLIDLY IN ADVISORY RANGE ACROSS NORTHERN 
OKLAHOMA. GIVEN THAT ARCTIC OUTBREAKS OF THIS MAGNITUDE...AND 
WIDESPREAD FRESH SNOW COVER...ARE RELATIVELY RARE...WE WILL CONTINUE 
A WIND CHILL ADVISORY THROUGH MORNING TO HIGHLIGHT THE STILL 
HAZARDOUS OUTDOOR CONDITIONS.

THE 12Z GFS AND NAM ARE GOOD INTO THE WEEKEND...THEN THE ECMWF WAS 
PREFERRED IN THE EXTENDED...BUT MODEL DIFFERENCES ARE MINOR. WE 
ANTICIPATE A STEADY WARMING TREND. SOME OF OUR WEST AND SOUTHWEST 
COUNTIES WILL RISE JUST ABOVE FREEZING THURSDAY...AND WIDESPREAD SUN 
WILL GET THE MELT-OFF STARTED. FOR THE FRIDAY TO SUNDAY 
TEMPERATURES...THE MOS GUIDANCE APPEARED TOO WARM IN THE FACE OF 
SNOW COVER...BUT DOWNSLOPE WIND...SUNSHINE...AND SUBSTANTIALLY 
WARMER 850 MB TEMPS LED US TO RAISE TEMPS A BIT FROM THE PREVIOUS 
FORECAST PACKAGE. UPPER LEVEL FLOW TURNS WESTERLY AND THEN GOES INTO 
SHORT TO MEDIUM WAVELENGTH RIDGING BY EARLY NEXT WEEK. NO
