A COUPLE MORE WEAK COLD FRONTS WILL AFFECT THE FA THIS WEEK. THESE
FRONTS WILL HAVE VERY LITTLE IMPACT ON THE AREA. THE FIRST WEAK
FRONT WILL MOVE ACROSS THE AREA LATE TONIGHT/WEDNESDAY AS A MID LVL
DISTURBANCE MOVES FROM THE CENTRAL ROCKIES INTO THE SOUTHERN PLAINS.
NO PRECIP IS EXPECTED WITH THIS FRONT AND DISTURBANCE. IN FACT THE
ONLY IMPACTS EXPECTED ARE A WIND SHIFT TO THE NORTH AND HAMPERING
ANY MAJOR WARM-UP WEDNESDAY. WARMER TEMPERATURES ARE EXPECTED
THURSDAY AND FRIDAY WITH HIGHS IN THE 60S AT MANY LOCATIONS BOTH
DAYS. THE WILDFIRE POTENTIAL WILL INCREASE LATE IN THE WORK WEEK DUE
TO THE WARM TEMPS AND LOW RH BUT WINDS ARE EXPECTED TO REMAIN BELOW
RED FLAG CRITERIA. THE SECOND MENTIONED WEAK COLD FRONT WILL MOVE
INTO AND ACROSS PARTS OF THE FA FRIDAY NIGHT AND SATURDAY. THIS
FRONT WILL COOL TEMPERATURES SOME SATURDAY COMPARED TO THE LATTER
HALF OF THE WORK WEEK BUT STILL REMAIN WELL ABOVE NORMAL WITH TEMPS
IN THE 50S AND LOW 60S.
COOLER TEMPS...CLOSER TO NORMAL... WILL BE POSSIBLE SUNDAY.
PRECIPITATION WILL ALSO BE POSSIBLE SUNDAY AND SUNDAY NIGHT IN SOUTH
AND EASTERN PORTIONS OF THE FA... AS A DISTURBANCE MOVES ACROSS
TEXAS. IT IS AROUND THIS TIME THAT THE GFS AND ECMWF BEGIN TO
DIVERGE. THE ECMWF HAS A STRONG SURGE OF ARCTIC AIR MOVING INTO THE
REGION SUNDAY NIGHT AND MONDAY WITH PRECIP POSSIBLE. THE PRECIP THEN
MOVES EAST OF THE AREA MONDAY NIGHT AS UPPER LEVEL DISTURBANCE MOVES
EAST OF THE FA. MEANWHILE... THE GFS DOES ALSO SHOW SOME COLD AIR
MOVING IN SUNDAY NIGHT/MONDAY BUT HOLDS MOST OF THE PRECIP WEST OR
AT LEAST IN WESTERN PORTIONS OF THE FA UNTIL MON NIGHT AND TUES WHEN
IT FINALLY MOVES EAST ACROSS THE FA AS A DISTURBANCE MOVES EAST
ACROSS THE SOUTHERN PLAINS. WITH THE DIFFERENCES/INCONSISTENCIES
HAVE LOW POPS IN THROUGH MONDAY THEN WILL KEEP DRY PAST THAT TIME
FOR NOW. WITH THE COLD AIR MOVING INTO THE REGION DURING THIS TIME
FRAME... HAVE A MENTION OF WINTRY PRECIP IN THE FORECAST.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
429 AM CST THU JAN 27 2011
.DISCUSSION...
DECENT WARMUP NEXT FEW DAYS WITH DOWNSLOPE WESTERLIES AT THE SFC.
NAM12 SFC T HAS DONE WELL RECENTLY ON THE HIGHS ACCORDING TO LOCAL
VERIFICATION DATA. RECENT RUNS SUPPORT 60S TODAY AND LOW 70S
FRIDAY OVER MOST OF THE AREA. MOST RECENT NAM AND ECMWF RUNS HOLD
OFF ANY BACK-DOOR COLD INTRUSIONS INTO OK UNTIL SAT NIGHT... SO
SATURDAY ALSO IS LIKELY TO FEATURE SPRINGLIKE TEMPS OVER MOST OF
THE AREA. FRONT IS LIKELY TO BE VERY CLOSE TO FAR N OK IF NOT INTO
THE STATE... SO HIGHS ON SATURDAY COULD STILL BE A CHALLENGE NEAR
THE KS BORDER. WILDFIRE POTENTIAL WILL BE ELEVATED EACH AFTERNOON
THROUGH SATURDAY DUE TO WARM DRY CONDITIONS... BUT WINDS WILL BE
RELATIVELY LIGHT MOST OF THE TIME. SATURDAY MAY BE THE DAY OF
GREATEST CONCERN DUE TO SLIGHTLY STRONGER WINDS.
CHILLDOWN IS LIKELY TO COMMENCE SAT NIGHT AND SUNDAY AS SFC FRONT
MOVES S IN WAKE OF AN UPPER LOW MOVING ACROSS N TX. WE WILL KEEP
SOME LOW POPS GOING FOR -RA OVER MUCH OF THE SE PART OF THE CWA
SAT NIGHT AND SUNDAY. ANY PRECIP SHOULD END BEFORE ENOUGH COLD AIR
ARRIVES TO FORCE A CHANGEOVER.
FIRST PART OF NEXT WEEK IS LOOKING MORE TROUBLESOME IN TERMS OF SNOW
AND ICE. MED-RANGE MODELS STILL DIFFER ON TIMING OF THE SYSTEM
ARRIVING ON THE OR-CA COAST EARLY SUNDAY AND INTO THE S PLAINS FIRST
HALF OF NEXT WEEK. BUT THEY APPEAR TO BE CONVERGING ON A SCENARIO
THAT WOULD GIVE US A PRECIP LULL AROUND MONDAY IN WAKE OF THE
WEEKEND SYSTEM... FOLLOWED BY INCREASIHG CHANCES MON NIGHT THROUGH
TUE NIGHT. PROBLEM IS THAT THE CANADIAN AIR WILL BE ON THE OFFENSIVE
DURING THIS PERIOD AND WILL EITHER BE MOVING INTO THE AREA OR WILL
ALREADY BE IN PLACE. ECMWF REMAINS MORE AGGRESSIVE THAN THE GFS ON
THE ARCTIC HIGH INTRUSION INTO THE S PLAINS MONDAY... AND WOULD BE

THE ECMWF IN FACT HAS BACKED OFF FROM YESTERDAY'S 1051 HIGH OVER

DECENT WARMUP NEXT FEW DAYS WITH DOWNSLOPE WESTERLIES AT THE SFC.
NAM12 SFC T HAS DONE WELL RECENTLY ON THE HIGHS ACCORDING TO LOCAL
VERIFICATION DATA. RECENT RUNS SUPPORT 60S TODAY AND LOW 70S
FRIDAY OVER MOST OF THE AREA. MOST RECENT NAM AND ECMWF RUNS HOLD
OFF ANY BACK-DOOR COLD INTRUSIONS INTO OK UNTIL SAT NIGHT... SO
SATURDAY ALSO IS LIKELY TO FEATURE SPRINGLIKE TEMPS OVER MOST OF
THE AREA. FRONT IS LIKELY TO BE VERY CLOSE TO FAR N OK IF NOT INTO
THE STATE... SO HIGHS ON SATURDAY COULD STILL BE A CHALLENGE NEAR
THE KS BORDER. WILDFIRE POTENTIAL WILL BE ELEVATED EACH AFTERNOON
THROUGH SATURDAY DUE TO WARM DRY CONDITIONS... BUT WINDS WILL BE
RELATIVELY LIGHT MOST OF THE TIME. SATURDAY MAY BE THE DAY OF
GREATEST CONCERN DUE TO SLIGHTLY STRONGER WINDS.
CHILLDOWN IS LIKELY TO COMMENCE SAT NIGHT AND SUNDAY AS SFC FRONT
MOVES S IN WAKE OF AN UPPER LOW MOVING ACROSS N TX. WE WILL KEEP
SOME LOW POPS GOING FOR -RA OVER MUCH OF THE SE PART OF THE CWA
SAT NIGHT AND SUNDAY. ANY PRECIP SHOULD END BEFORE ENOUGH COLD AIR
ARRIVES TO FORCE A CHANGEOVER.
FIRST PART OF NEXT WEEK IS LOOKING MORE TROUBLESOME IN TERMS OF SNOW
AND ICE. MED-RANGE MODELS STILL DIFFER ON TIMING OF THE SYSTEM
ARRIVING ON THE OR-CA COAST EARLY SUNDAY AND INTO THE S PLAINS FIRST
HALF OF NEXT WEEK. BUT THEY APPEAR TO BE CONVERGING ON A SCENARIO
THAT WOULD GIVE US A PRECIP LULL AROUND MONDAY IN WAKE OF THE
WEEKEND SYSTEM... FOLLOWED BY INCREASIHG CHANCES MON NIGHT THROUGH
TUE NIGHT. PROBLEM IS THAT THE CANADIAN AIR WILL BE ON THE OFFENSIVE
DURING THIS PERIOD AND WILL EITHER BE MOVING INTO THE AREA OR WILL
ALREADY BE IN PLACE. ECMWF REMAINS MORE AGGRESSIVE THAN THE GFS ON

.DISCUSSION...
VERY WARM TEMPERATURES ARE IN STORE FOR THE NEXT COUPLE OF DAYS...
ALTHOUGH THERE IS SOME DISAGREEMENT IN THE MODELS ABOUT HOW FAR A
COLD FRONT WILL MOVE SOUTH ON SATURDAY. GFS BRINGS FRONT INTO THE
NORTHERN THIRD OF THE CWA BY 00Z/SUNDAY WHILE ECMWF AND ESPECIALLY
THE NAM KEEP THE FRONT NORTH OF THE AREA. IN COORDINATION WITH THE
ADJACENT KANSAS OFFICES... WILL GO CLOSER TO THE WARMER NAM
SOLUTION FOR SATURDAY AT THIS POINT. ALL THE MODELS DO SHOW THE
COLD FRONT MOVING THROUGH THE AREA SATURDAY NIGHT AND SUNDAY
MORNING BEGINNING A MUCH COOLER PERIOD OF TIME. REINFORCING SHOTS
OF COLD AIR LOOKS TO COME IN EARLY NEXT WEEK WITH TEMPERATURES
COLDEST TEMPERATURES EXPECTED ON TUESDAY AND WEDNESDAY.
PRECIPITATION FORECAST IS STILL TRICKY. AT LEAST SLIGHT
PRECIPITATION CHANCES BEGIN ON SATURDAY NIGHT AND PERSIST INTO
EARLY NEXT WEEK. MEDIUM RANGE MODELS DO INCREASE THE
PRECIPITATION CHANCES NEXT WEEK ALTHOUGH THERE ARE SIGNIFICANT
DIFFERENCES IN THE LOCATION AND TIMING OF THE PRECIPITATION... AND
STILL UNCERTAINTY ON PRECIPITATION TYPE ESPECIALLY EARLY IN THE
EVENT. SURFACE FRONT WILL BE WELL TO THE SOUTH OF THE AREA AND
ISENTROPIC ANALYSIS SHOWS DECENT MOISTURE FEED AND LIFT ABOVE THE
FRONTAL SURFACE... BUT NOT IN THE TYPICAL CONFIGURATION FOR US.
INSTEAD OF A MOIST SOUTHERLY FLOW ABOVE THE FRONTAL SURFACE... THE
MOIST FLOW IS A EAST TO WEST FLOW FROM ARKANSAS DESPITE THE LACK
OF A STRONG LOW-LEVEL CYCLONE. SO THERE IS THE UNCERTAINTY ABOUT
MOISTURE AVAILABILITY FOR THE STORM SYSTEM EARLY NEXT WEEK
ESPECIALLY GIVEN THE POOR TRACK RECORD OF THE MOISTURE RETURN IN
THE MODELS WITH SOME OF THE RECENT NON-EVENTS. REGARDLESS AT THIS
POINT... CHANCE POPS ARE WARRANTED ON MONDAY NIGHT TO TUESDAY
NIGHT ALTHOUGH GEOGRAPHIC AND SIGNIFICANCE DETAILS ARE STILL VERY
MUCH IN QUESTION. AND AT THIS POINT ALL OF THE MEDIUM RANGE MODELS
SUGGEST THAT PRECIPITATION WILL END TUESDAY NIGHT SO WEDNESDAY AND

SOUTHWEST WINDS WILL DECREASE THIS EVENING WITH CLEAR SKIES. SFC
BOUNDARY WILL APPROACH NORTHERN TAF SITES BY LATE SATURDAY MORNING
WITH SOME VARIABILITY IN WIND DIRECTIONS...HOWEVER SPEEDS SHOULD
REMAIN BELOW 10KTS. UPPER STORM SYSTEM WILL BEGIN TO MOVE EAST INTO
SOUTHWEST TEXAS ON SATURDAY. THIS WILL BRING SOME MID/HIGH CLOUDS
TOWARD RED RIVER.

.UPDATE...
MAIN CHANGE TO THE PACKAGE THIS MORNING WAS TO DECREASE DEWPOINTS
IN WESTERN OKLAHOMA AND WESTERN NORTH TEXAS BASED ON CURRENT
TRENDS AND EXPECTED CONTINUED DRY.. WESTERLY SURFACE FLOW. THIS
BRINGS MINIMUM RH VALUES TO LESS THAN 20 PERCENT ACROSS A LARGER
AREA OF OKLAHOMA AND NORTH TEXAS ENHANCING WILDFIRE POTENTIAL
DESPITE THE LACK OF STRONG WINDS. ALSO HAVE RAISED MAX
TEMPERATURES SOMEWHAT IN THE EASTERN PART OF THE FORECAST AREA.

VFR CONDITIONS WILL PREVAIL THROUGH THE FORECAST PERIOD WITH ONLY
A FEW HIGH CLOUDS EXPECTED. LIGHT TO MODERATE W TO SW WINDS WILL
PREVAIL THROUGH THE DAY BEFORE DECREASING AND BACKING TO THE
SOUTH TONIGHT.
PREV DISCUSSION... /ISSUED 410 AM CST FRI JAN 28 2011/
DISCUSSION...
FASTEN THE SEAT BELTS... THE WEATHER'S ROLLER COASTER RIDE IS
STARTING UP. TEMPERATURES WILL INITIALLY WARM UP TO WELL ABOVE
NORMAL BEFORE THEY PLUNGE INTO THE ICY COLD.
WEST TO SOUTHWEST WINDS AND GENERALLY SUNNY SKIES WILL ALLOW
TEMPERATURES TO WARM INTO THE UPPER 60S TO MID 70S OVER A GOOD
PART OF THE REGION TODAY. THE UNSEASONABLY WARM TEMPERATURES AND
DRY AIR WILL RESULT IN LOW HUMIDITIES BY THIS AFTERNOON WHICH WILL
INCREASE FIRE WEATHER CONCERNS... ESPECIALLY OVER WESTERN PORTIONS
OF OK AND NORTH TX. HOWEVER... IT APPEARS THE WINDS WILL BE
ON THE MODERATE SIDE... GENERALLY RUNNING 15 MPH OR LOWER...
ALTHOUGH MIXING COULD RESULT IN SOME GUSTS AROUND 20 MPH.
TEMPERATURES WILL BE A BIT COOLER ON SUNDAY IN NORTHERN OK AS A
COLD FRONT WAFFLES INTO THE AREA... BUT HIGHS WILL STILL RUN WELL
ABOVE SEASONAL AVERAGES IN MOST AREAS.
AN UPPER LOW... LOCATED OFF THE COAST OF NORTHERN BAJA EARLY THIS
MORNING... WILL LIFT OUT TO THE EAST DURING THE NEXT COUPLE OF
DAYS. WHILE MOST OF THE RAIN WITH THIS SYSTEM IS EXPECTED TO BE
WILL BE OVER EASTERN TX... SOME OF IT MAY ALSO SPILL INTO SE OK.
MEANWHILE... A LARGE COLD HIGH PRESSURE RIDGE OVER CANADA WILL
DROP SOUTHWARD AND PUSH A COLD FRONT THROUGH THE AREA SATURDAY
NIGHT AND EARLY SUNDAY... DROPPING HIGH TEMPERATURES 20 TO 25
DEGREES FOR SUNDAY. SOME LIGHT MIXED WINTRY PRECIPITATION WILL BE
POSSIBLE SUNDAY NIGHT INTO MONDAY MAINLY ACROSS NORTHERN OK WITH
LIGHT RAIN/DRIZZLE FARTHER SOUTH.
AS TEMPERATURES CONTINUE TO CHILL DOWN... ANOTHER STORM SYSTEM WILL
APPROACH THE AREA EARLY NEXT WEEK... BRINGING A BETTER POSSIBILITY
FOR A MIX OF WINTER PRECIPITATION. WHILE THE DETAILS DIFFER AMONG
THE MODELS... BOTH THE GFS AND ECMWF SPREAD SOME PRECIPITATION
OVER THE AREA BY TUESDAY... WITH THE GFS STARTING IT A LITTLE
SOONER AND GENERATING MORE QPF IN GENERAL. THE CHANCE FOR
FREEZING/FROZEN PRECIP WILL PROGRESS SOUTH THROUGH THE FA MONDAY
NIGHT AND TUESDAY. WHILE THERE IS REASONABLE CONFIDENCE IN THE

OFF MEXICAN PLATEAU. WEAK SFC FRONT MAY SLIP INTO NORTHERN OKLAHOMA
DURING THE DAY... BUT SHOULD DO LITTLE MORE THAN ACT AS A WIND SHIFT.
THERE WILL CONT TO BE FIRE WX CONCERNS ON SAT AS VERY WARM... BREEZY

UPPER WAVE NEAR BAJA WILL EJECT EAST THROUGH TX OVER THE WEEKEND
BRINGING A SLIGHT CHANCE OF RAIN TO PORTIONS OF SOUTHERN OKLAHOMA.
AS THIS WAVE MOVES BY IT WILL BEGIN TO BRING SOUTH COOLER AIR
CURRENTLY ACROSS THE NORTHERN PLAINS. OUR ATTENTION THEN TURNS TO
UPPER WAVE OFF THE PACIFIC NORTHWEST COAST AND ITS MOVEMENT TOWARD

ACROSS CANADA. AT LEAST DEPICTED BY THE MODELS TO TAKE SHAPE.
LATEST RUNS OF BOTH THE GFS AND ECMWF HAVE SHOWN THAT AS THE
INITIAL WAVE APPROACHES FROM THE WEST OF MONDAY... WARMER AIR WILL
TRY AND MOVE BACK NORTH INTO PART OF OKLAHOMA AS MORE SIGNIFICANT
SFC CYCLOGENESIS DEVELOPS TO OUR WEST/SOUTHWEST. THIS WARMER AIR
APPEARS THAT IT MAY LIMIT FREEZING/FROZEN PRECIP ACROSS MUCH OF THE
AREA MONDAY NIGHT.
MODEL TRENDS WOULD BRING DEEPER/COLDER AIR SOUTHWARD INTO AREA
DURING THE DAY ON TUESDAY AS SFC LOW CONT TO DEEPEN TO OUR SOUTH AND
SOUTHEAST. THIS SHOULD ALLOW A QUICKER TRANSITION FROM LIQUID TO
FROZEN... LIMITING FREEZING RAIN AND SLEET. IN ADDITION LATEST ECMWF

LIMITING SNOW ACROSS THE AREA. HOWEVER CONFIDENCE ON ANY PARTICULAR

TEMPERATURES TODAY WILL AGAIN BE UNSEASONABLY WARM ACROSS MUCH OF

WEATHER CONCERNS WILL CONTINUE ESPECIALLY IN THE SOUTHWEST WHERE
HUMIDITIES WILL LIKELY FALL TO NEAR 10 PERCENT. AT THIS TIME IT
APPEARS THAT THE WINDS WILL REMAIN MODEST WITH SPEEDS AVERAGING
ONLY 10 TO 15 MPH WITH OCCASIONAL GUSTS TO AROUND 20 MPH.
A COLD FRONT WILL BEGIN MOVING SOUTH THROUGH THE AREA TONIGHT REACHING
SE OK BY EARLY SUNDAY MORNING. MEANWHILE... AN UPPER LEVEL STORM
SYSTEM OVER BAJA WILL TRACK ENE ACROSS TX TONIGHT AND SUNDAY. WHILE
MOST OF THE PRECIPITATION WITH THIS SYSTEM WILL BE IN EASTERN
TX... A FEW SHOWERS COULD ALSO SPREAD INTO THE SOUTHEAST PART OF
OUR CWA TONIGHT AND SUNDAY. WOULD NOT RULE OUT A CLAP OF THUNDER
OR TWO OVERNIGHT. TEMPERATURES ON SUNDAY WILL AVERAGE ABOUT 25
DEGREES COLDER THAN TODAY.
THE NEXT MAJOR UPPER STORM SYSTEM TO AFFECT US WILL BE DROPPING INTO
THE SW US BY MONDAY MORNING. ALTHOUGH WE WILL BE IN BETWEEN UPPER
SYSTEMS SUNDAY NIGHT AND MONDAY... THERE STILL COULD BE SOME
SCATTERED LIGHT DRIZZLE... WITH FREEZING DRIZZLE IN NORTHERN OK...
DEVELOPING BEHIND THE FRONT. ANY ACCUMULATION SHOULD BE VERY
LIGHT.
THE WEATHER IS EXPECTED TO DETERIORATE MONDAY NIGHT AND TUESDAY AS
COLDER AIR CONTINUES TO SPREAD INTO THE REGION WHILE THE UPPER SYSTEM
BEGINS TO MOVE INTO THE SOUTHERN PLAINS. AS TEMPERATURES FALL BELOW
FREEZING OVER A GOOD PART OF CENTRAL... WESTERN AND NORTHERN
OKLAHOMA... A MIXED BAG OF FREEZING/FROZEN PRECIPITATION IS EXPECTED.
THE WINTRY MIX IS EXPECTED TO SPREAD OVER THE REMAINDER OF THE AREA
ON TUESDAY. ATTM... IT APPEARS THE MOSTLY LIKELY AREA FOR THE
HEAVIER SNOW ACCUMULATIONS... PERHAPS 2-4 INCHES... MAY BE OVER
PARTS OF N-CENTRAL INTO WEST CENTRAL OK. SOME ICE WILL ALSO
POSSIBLE MAINLY OVER PARTS OF NORTH CENTRAL INTO CENTRAL OK.
HOWEVER... THIS FAR OUT... THE CONFIDENCE LEVEL IN PREDICTING
SPECIFIC AMOUNTS REMAINS LOW DUE TO UNCERTAINTIES IN THE TIMING
OF THE PRECIPITATION PHASE CHANGES AS IT RELATES TO THE QPF FIELDS.
AS THE UPPER SYSTEMS MOVES THROUGH... MUCH COLDER AIR WILL SURGE
INTO THE AREA ON THE HEELS OF STRONG NORTH WINDS. IT MAY BE THAT
THE HIGHS FOR TUESDAY OCCUR EARLY WITH TEMPERATURES FALLING AS
THE DAY PROGRESSES. THE STRONG WINDS AND FALLING TEMPERATURES
STILL LOOK FAVORABLE FOR GENERATING SUBZERO WIND CHILLS OVER A
GOOD PART OF THE CENTRAL... WEST AND NORTH TUESDAY NIGHT AND

VFR CONDITIONS ARE EXPECTED THROUGH 00Z WITH OCCASIONAL BKN HIGH
CLOUDS SPREADING IN THIS AFTERNOON. A WEAK SURFACE TROUGH IN
NORTHERN OK WILL DRIFT BACK NORTH INTO KS TODAY. A COLD FRONT WILL
MOVE SOUTH INTO NORTHERN OK AROUND 00Z... REACHING TO NEAR THE RED

TEMPERATURES TODAY WILL AGAIN BE UNSEASONABLY WARM ACROSS MUCH OF
THE AREA WITH HIGHS IN MOST LOCATIONS REACHING THE 70S. FIRE
WEATHER CONCERNS WILL CONTINUE ESPECIALLY IN THE SOUTHWEST WHERE
HUMIDITIES WILL LIKELY FALL TO NEAR 10 PERCENT. AT THIS TIME IT
APPEARS THAT THE WINDS WILL REMAIN MODEST WITH SPEEDS AVERAGING
ONLY 10 TO 15 MPH WITH OCCASIONAL GUSTS TO AROUND 20 MPH.
A COLD FRONT WILL BEGIN MOVING SOUTH THROUGH THE AREA TONIGHT REACHING
SE OK BY EARLY SUNDAY MORNING. MEANWHILE... AN UPPER LEVEL STORM
SYSTEM OVER BAJA WILL TRACK ENE ACROSS TX TONIGHT AND SUNDAY. WHILE
MOST OF THE PRECIPITATION WITH THIS SYSTEM WILL BE IN EASTERN
TX... A FEW SHOWERS COULD ALSO SPREAD INTO THE SOUTHEAST PART OF
OUR CWA TONIGHT AND SUNDAY. WOULD NOT RULE OUT A CLAP OF THUNDER
OR TWO OVERNIGHT. TEMPERATURES ON SUNDAY WILL AVERAGE ABOUT 25
DEGREES COLDER THAN TODAY.
THE NEXT MAJOR UPPER STORM SYSTEM TO AFFECT US WILL BE DROPPING INTO
THE SW US BY MONDAY MORNING. ALTHOUGH WE WILL BE IN BETWEEN UPPER
SYSTEMS SUNDAY NIGHT AND MONDAY... THERE STILL COULD BE SOME
SCATTERED LIGHT DRIZZLE... WITH FREEZING DRIZZLE IN NORTHERN OK...
DEVELOPING BEHIND THE FRONT. ANY ACCUMULATION SHOULD BE VERY
LIGHT.
THE WEATHER IS EXPECTED TO DETERIORATE MONDAY NIGHT AND TUESDAY AS
COLDER AIR CONTINUES TO SPREAD INTO THE REGION WHILE THE UPPER SYSTEM
BEGINS TO MOVE INTO THE SOUTHERN PLAINS. AS TEMPERATURES FALL BELOW
FREEZING OVER A GOOD PART OF CENTRAL... WESTERN AND NORTHERN
OKLAHOMA... A MIXED BAG OF FREEZING/FROZEN PRECIPITATION IS EXPECTED.
THE WINTRY MIX IS EXPECTED TO SPREAD OVER THE REMAINDER OF THE AREA
ON TUESDAY. ATTM... IT APPEARS THE MOSTLY LIKELY AREA FOR THE
HEAVIER SNOW ACCUMULATIONS... PERHAPS 2-4 INCHES... MAY BE OVER
PARTS OF N-CENTRAL INTO WEST CENTRAL OK. SOME ICE WILL ALSO
POSSIBLE MAINLY OVER PARTS OF NORTH CENTRAL INTO CENTRAL OK.
HOWEVER... THIS FAR OUT... THE CONFIDENCE LEVEL IN PREDICTING
SPECIFIC AMOUNTS REMAINS LOW DUE TO UNCERTAINTIES IN THE TIMING
OF THE PRECIPITATION PHASE CHANGES AS IT RELATES TO THE QPF FIELDS.
AS THE UPPER SYSTEMS MOVES THROUGH... MUCH COLDER AIR WILL SURGE
INTO THE AREA ON THE HEELS OF STRONG NORTH WINDS. IT MAY BE THAT
THE HIGHS FOR TUESDAY OCCUR EARLY WITH TEMPERATURES FALLING AS
THE DAY PROGRESSES. THE STRONG WINDS AND FALLING TEMPERATURES
STILL LOOK FAVORABLE FOR GENERATING SUBZERO WIND CHILLS OVER A
GOOD PART OF THE CENTRAL... WEST AND NORTH TUESDAY NIGHT AND
WEDNESDAY.
ANOTHER DISTURBANCE WILL APPROACH THE AREA BY EARLY WEDNESDAY.
WHILE WILL WE STAY WITH A DRY FORECAST FOR THAT TIME PERIOD... WE MAY
NEED TO EVENTUALLY ADD SOME FLURRIES OR SMALL CHANCES OF LIGHT
SNOW.

THE INITIAL COLD FRONT IS PROGRESSING SOUTH ACROSS OUR FAR
NORTHERN COUNTIES. IT APPEARS TO BE RIGHT ON SCHEDULE... AND
SHOULD REACH OKLAHOMA CITY AROUND MIDNIGHT... THEN EXIT OUT
FORECAST AREA TOMORROW MORNING AROUND SUNRISE. PRE-FRONTAL WINDS
HAVE DROPPED OFF A LOT... AND TEMPERATURES JUST AHEAD OF THE FRONT
HAVE DROPPED DRAMATICALLY AS VERY DRY AIR... LIGHT WINDS... AND
CLEAR SKIES ALLOW FOR VERY EFFICIENT RADIATIONAL COOLING. ONCE THE
FRONT ARRIVES... MANY OF THOSE LOCATIONS WILL SEE THE TEMPERATURE
RISE SUBSTANTIALLY... BEFORE FALLING BACK AGAIN AS THE COLD-AIR
ADVECTION SETS IN.
OTHER THAN THE WIND SHIFT... AND SIGNIFICANT INCREASE IN WIND
SPEEDS... FIRE WEATHER CONDITIONS WILL BECOME MUCH LESS SUPPORTIVE
OF WILDFIRES OVERNIGHT.
FINALLY... A FEW THUNDERSTORMS HAVE FORMED OVER TEXAS... SOUTHWEST
OF THE METROPLEX. THERE IS A SMALL CHANCE THAT SOME OF THIS
CONVECTION WILL AFFECT PARTS OF SOUTH-CENTRAL AND SOUTHEAST
OKLAHOMA OVERNIGHT. IT IS IMPROBABLE THAT THUNDERSTORMS WILL OCCUR
AS FAR NORTH AS OUR FORECAST AREA... BUT A FEW SHOWERS ARE CERTAINLY A
POSSIBILITY.
THE CURRENT FORECAST GENERALLY LOOKS GOOD... OTHER THAN BEING
UNABLE TO ACCOUNT FOR THE WILDLY VARYING TEMPERATURES OVER SHORT
DISTANCES... DUE TO TERRAIN FEATURES AND RADIATIONAL COOLING. AT
THIS TIME... NO UPDATES ARE PLANNED FOR THE OVERNIGHT FORECAST.

LOW-LEVEL MOISTURE IS MAINTAINING A LARGE AREA OF CLOUD COVER OVER
OUR FORECAST AREA THIS EVENING. THE SOUTHERN EDGE OF THE CLOUDS
FORMS A ZIGZAG PATTERN ACROSS THE SOUTHERN PART OF OUR AREA. THE
WIND PATTERN OVER THE NEXT 24 HOURS OR SO SUGGESTS THAT THE
SOUTHERN EDGE MAY WELL REMAIN FAIRLY RAGGED... AND THAT OUR TEXAS
AND SOUTHERN OKLAHOMA COUNTIES MAY SEE A LITTLE SUN NOW AND THEN
DURING THE DAY TOMORROW. WE WILL RAISE THE DAYTIME TEMPERATURES A
BIT FOR THE SOUTH AS A RESULT. THIS... HOWEVER... IS A LOW-
CONFIDENCE CHANGE.
SIMILARLY... PERSISTENT CLOUD COVER WILL HOLD TEMPERATURES UP
OVERNIGHT OVER MOST OF OKLAHOMA. THIS MEANS THAT WE WILL RAISE
MINIMUM TEMPERATURES SIGNIFICANTLY IN A FEW SPOTS IN NORTHERN
OKLAHOMA. THIS WILL ALSO LEAD TO NON-DIURNAL TEMPERATURE PATTERNS
TOMORROW... AS DAYTIME HIGHS IN MANY PLACES WILL BE REACHED EARLY
IN THE DAY.
RADAR IN HIGH-SENSITIVITY MODE SHOWS SOME WEAK ECHOES... ALTHOUGH
SURFACE REPORTS SHOW NOTHING HITTING THE GROUND AT THIS POINT.
GIVEN THE SATURATED LOW-LEVELS OF THE ATMOSPHERE... AND SOME WEAK
ISENTROPIC LIFT FORECAST OVERNIGHT... WE WILL RETAIN THE DRIZZLE
AND FREEZING DRIZZLE CHANCES NEAR AND EAST OF I-35.
THE BIG STORM TOMORROW NIGHT AND TUESDAY STILL LOOKS LIKE IT WILL
BE MAINLY SNOW... EXCEPT OVER SOUTH-CENTRAL AND SOUTHEAST
OKLAHOMA... WHERE A LONGER PERIOD OF FREEZING DRIZZLE/RAIN OR
SLEET APPEARS MORE LIKELY. MODEL DATA ARE STILL COMING IN... SO WE
WILL NOT MAKE ANY CHANGES TO LATER PERIODS AT THIS POINT.

MAIN FOCUS CONTINUES TO BE ON DEVELOPING WINTER STORM THAT WILL
AFFECT THE AREA TONIGHT AND TUESDAY. UNTIL THEN... MOSTLY CLOUDY
AND COOL CONDITIONS WILL PREVAIL TODAY WITH SOME PATCHES OF VERY LIGHT
DRIZZLE/FREEZING DRIZZLE POSSIBLE ACROSS NORTHERN OKLAHOMA. BY
TONIGHT... AN UPPER LEVEL STORM SYSTEM WILL MOVE FROM THE SW US
AND INTO THE SOUTHERN PLAINS. AT THE SAME TIME... A STRONG HIGH
PRESSURE RIDGE WILL BUILD SOUTHWARD THROUGH THE PLAINS BRINGING
MUCH COLDER TEMPERATURES TO THE REGION. THE PAST FEW MODEL RUNS
CONTINUE TO SHOW PRETTY GOOD CONSISTENCY REGARDING THE LOCATION
AND AMOUNTS OF THE HEAVIER SNOWFALL. WE ARE STILL LOOKING FOR THE
HIGHEST AMOUNTS TO BE ACROSS CENTRAL AND NORTH CENTRAL OK WHERE
4-8 INCHES ARE EXPECTED... WITH ISOLATED HIGHER TOTALS POSSIBLE.
HOWEVER... WHILE WE HAVE NOTED THAT THE LATEST 06Z NAM DEVELOPS A
RATHER SHARP SNOWFALL GRADIENT GENERALLY NW OF I-44 IN CENTRAL
OK... WE WILL SEE IF THAT TREND PERSISTS IN OTHER MODELS AND LATER
RUNS.
WE EXPECT FREEZING/FROZEN PRECIPITATION TO DEVELOP THIS EVENING
AND INCREASE THROUGH THE NIGHT. AS THE COLD AIR DEEPENS... THE
MIXED PRECIPITATION WILL CHANGE OVER TO SNOW FROM NW TO SE TONIGHT
AND INTO EARLY TUESDAY. THE SOUTHEAST COULD SEE THE MOST ICE WITH
SOME FREEZING RAIN AND SLEET. THAT AREA WILL SHOULD ALSO HAVE THE
HIGHEST QPF AMOUNTS... BUT TIMING OF THE PHASE-CHANGES WILL BE
SOMEWHAT PROBLEMATIC. MEANWHILE... THE PRESENCE OF MID-LEVEL
CONVECTIVE INSTABILITY SUGGESTS THAT A FEW T-STORMS WILL ALSO BE
POSSIBLE OVER THE SOUTHERN HALF OF OK AND N-TX TONIGHT.
THE PRECIPITATION SHOULD DECREASE IN INTENSITY BY MIDDAY
TUESDAY... ALTHOUGH LIGHT SNOW COULD PERSIST THROUGH EARLY
EVENING. THE OTHER SIGNIFICANT ISSUE WILL BE THE STRONG WINDS AND
VERY COLD TEMPERATURES POURING INTO THE REGION TONIGHT AND
TUESDAY. NOT ONLY COULD THE WINTRY PRECIPITATION MAKE TRAVEL
HAZARDOUS... BUT DANGEROUS WIND CHILLS WILL ALSO BE A HAZARD FOR
ANYONE CAUGHT OUT IN THE WEATHER.

ACCUMULATION LIKELY BEFORE PRECIP CHANGES TO SLEET AND

TREACHEROUS AT TIMES. INCREASED SNOWFALL AMOUNTS FARTHER SOUTH
INTO PARTS OF NORTH TEXAS SOUTH CENTRAL OKLAHOMA... BUT THIS AREA
SHOULD SEE PRECIP END FIRST AS TROUGH LIFTS NORTHEAST BY18-20Z.
SUSTAINED WINDS HAVE BEEN IN THE 25 TO 30 RANGE...ESPECIALLY
ACROSS NORTHERN OKLAHOMA BUT A GENERALLY INCREASE WILL LIKELY
OCCUR DURING THE MORNING AS THE SURFACE LOW DEEPENS AS IT MOVES
NORTHEAST INTO ARKATEX REGION. FREQUENT GUSTS TO 40 HAVE ALSO
BEEN SEEN ACROSS WESTERN PARTS OF THE STATE.
AS SYSTEM MOVES EAST OF THE AREA LATE TODAY...CONSIDERABLE BLOWING
AND DRIFTING OF SNOW WILL OCCUR AS WINDS WILL REMAIN STRONG.
AS WINTER STORM/BLIZZARD WARNINGS ARE CANCELLED/EXPIRE WILL LIKELY
NEED TO PLACE MANY AREAS IN A WIND CHILL ADVISORY TONIGHT INTO WEDNESDAY.
COLD WILL BE THE STORY THROUGH THE END OF THE WEEK AS THE COLD SURFACE

.DISCUSSION...WE HAVE SEEN THE BENEFITS OF EARLY WARNING TODAY... AS
MOST PEOPLE APPEAR TO HAVE STAYED HOME DURING AN EXTREMELY DANGEROUS
COMBINATION OF COLD AND SNOW. THE WORST OF THE SNOWFALL HAD ENDED AS
OF MID AFTERNOON...WITH ONLY LIGHT SNOW REMAINING AND DWINDLING OVER
NORTHERN OKLAHOMA. IT IS IMPORTANT TO EMPHASIZE...HOWEVER...THAT
DANGEROUS OUTDOOR CONDITIONS ARE HERE TO STAY FOR AN EXTENDED TIME.
THE OKLAHOMA CLIMATOLOGICAL SURVEY TELLS US THAT EARLY THIS MORNING
THE OKLAHOMA MESONET AT BOISE CITY SET A RECORD FOR THAT OBSERVING
NETWORK...WITH A WIND CHILL TEMPERATURE OF 36 BELOW ZERO. EVEN THIS
AFTERNOON...WIND CHILLS ARE COMMONLY AROUND 10 BELOW FROM CENTRAL
OKLAHOMA NORTH AND WESTWARD. ALTHOUGH THE EXCESSIVE WIND SPEEDS AND
GUSTS WILL DIMINISH WHEN LOW PRESSURE PULLS AWAY TO OUR EAST THIS
EVENING...BRISK WINDS OF 15 TO 25 MPH WILL CONTINUE FOR AN EXTENDED
TIME...AS A LARGE ARCTIC HIGH BUILDS DOWN FROM THE NORTHERN PLAINS.
THIS IS AN EXCEPTIONAL ARCTIC OUTBREAK FOR OUR AREA...AND THE
EXTREME COLD WILL PERSIST THROUGH THURSDAY. WE HAVE REPLACED THE
WINTER STORM AND BLIZZARD WARNINGS WITH WIND CHILL ADVISORIES AND
WARNINGS THAT GO THROUGH THURSDAY MORNING.
WITH THE BRISK WINDS...ADVECTION AND MIXING WILL BE THE DOMINANT
INFLUENCE ON LOW TEMPERATURES TONIGHT. MANY LOCATIONS WILL SEE AIR
TEMPERATURE DROP JUST BELOW ZERO FAHRENHEIT. IT WILL BE EVEN COLDER
WEDNESDAY NIGHT WHEN THE CENTER OF HIGH PRESSURE ARRIVES OVER THE
FRESH SNOW FIELD. SOME WEAK WARM ADVECTION AT 700 MB WILL PROVIDE A
LITTLE CLOUD COVER AND PERHAPS SNOW FLURRIES IN NORTH TEXAS AND
SOUTHERN OKLAHOMA WEDNESDAY AND WEDNESDAY NIGHT...BUT AREAS FARTHER
NORTH SHOULD BE RELATIVELY CLEAR...WITH AMPLE OPPORTUNITY TO RADIATE
AT NIGHT...RESULTING IN LOWS APPROACHING 10 BELOW. WINDS WILL BE
LIGHTER BY THAT TIME.
DOWNSLOPE WARMING WILL TAKE PLACE THURSDAY-FRIDAY...AND ESPECIALLY
SATURDAY WHEN A WARM FRONT LIFTS THROUGH FROM THE WEST. WE MODIFIED
THE GUIDANCE TEMPS BASED ON THE EXISTING SNOW COVER. ONCE WE THAW
OUT FROM THIS CURRENT STORM...ANOTHER ARCTIC FRONT WILL START TO
DOMINATE HEADLINES. THERE IS GOOD MODEL AGREEMENT...WITH AN ARCTIC
HIGH AND LOW WIND CHILL TEMPERATURES BUILDING IN SUNDAY NIGHT AND
MONDAY. THIS SYSTEM WILL NOT BE A MAJOR STORM...BUT THERE APPEARS TO
BE ENOUGH UPPER SUPPORT IN NORTHWEST FLOW...TO RESULT IN A FRONTAL
BAND OF PRECIPITATION CHANGING OVER TO SNOW SUNDAY NIGHT AND MONDAY.

WINTER PRECIPITATION... ALTHOUGH THE TYPE AND AMOUNT OF WINTER
PRECIPTIATION IS STILL UNCERTAIN.
A COLD FRONT WILL MOVE INTO THE AREA LATE SATURDAY INTO SUNDAY. THIS
WILL LEAD TO COOLER CONDITIONS SUNDAY WITH HIGH TEMPERATURES CLOSER
TO NORMAL. MEANWHILE... A DISTURBANCE WILL MOVE EAST ACROSS TEXAS
BRINGING A CHANCE OF LIGHT RAIN TO PARTS OF SOUTHERN AND CENTRAL
OKLAHOMA AND NORTH TEXAS SATURDAY NIGHT AND SUNDAY.
EVEN COOLER TEMPERATURES ARE EXPECTED MONDAY AS COOL AIR CONTINUES
TO MOVE INTO THE REGION. LOW PRECIPITATION CHANCES WILL EXPAND NORTH
AND WEST SUNDAY NIGHT AND MONDAY. MOST OF THE PRECIPITATION WILL
FALL IN THE FORM OF LIGHT RAIN OR DRIZZLE. HOWEVER... LIGHT WINTER
PRECIPITATION WILL BEGIN TO BE POSSIBLE ACROSS PARTS OF NORTHERN AND
MAYBE INTO CENTRAL OKLAHOMA.
THE BIGGEST CHANGES WILL OCCUR MONDAY NIGHT INTO TUESDAY. A MUCH
COLDER ARCTIC AIRMASS WILL MOVE INTO THE REGION TUESDAY... WITH
PRECIPITATION CHANCES INCREASING MONDAY NIGHT INTO TUESDAY AS AN
UPPER LEVEL STORM SYSTEM MOVES ACROSS THE REGION. THIS WILL LEAD TO
A CHANCE OF WINTER PRECIPITATION ACROSS PARTS OF OKLAHOMA AND
WESTERN NORTH TEXAS. THE PRECIPITATION IS EXPECTED TO END FROM WEST
TO EAST TUESDAY NIGHT. BRISK NORTH WINDS WILL ALSO ACCOMPANY THE
COLDER AIR LEADING TO EVEN COLDER WIND CHILLS... WITH BELOW ZERO
WIND CHILLS POSSIBLE TUESDAY NIGHT ACROSS A LARGE PORTION OF
OKLAHOMA AND PARTS OF WESTERN NORTH TEXAS.
AS FOR THE PRECIPITATION MONDAY NIGHT AND TUESDAY... THERE CONTINUES
TO BE UNCERTAINTIES AT ANY GIVEN LOCATION AS TO THE PRECIPITATION

HOW MUCH WINTER PRECIPITATION WILL OCCUR. SOME LOCATIONS ACROSS
PARTS OF OKLAHOMA AND WESTERN NORTH TEXAS MAY RECEIVE ONE TO ALL OF
THE TYPES OF RAIN... FREEZING RAIN... SLEET... AND SNOW. RESIDENTS
SHOULD CONTINUE TO MONITOR THE LATEST FORECASTS FOR UPDATES AS NEW
DATA IS RECEIVED.
IN THE MEAN TIME... PLEASANT WEATHER WILL OCCUR ACROSS THE REGION
TODAY AND SATURDAY WITH TEMPERATURES WELL ABOVE SEASONAL NORMALS.
THESE WARM TEMPERATURES AND THE DRY CONDITIONS WILL ELEVATE THE
WILDFIRE POTENTIAL TODAY AND SATURDAY. THE WORST FIRE WEATHER
CONDITIONS COULD BE SATURDAY AFTERNOON WHEN THERE IS THE POTENTIAL
