NOVEMBER 2004 WEATHER HIGHLIGHTS...

AT THE BEGINNING OF THE MONTH...AN UPPER LEVEL STORM SYSTEM 
MOVED ACROSS WEST TEXAS FROM NEW MEXICO. THE APPROACH OF THIS 
SYSTEM BROUGHT NUMEROUS SHOWERS AND THUNDERSTORMS TO WEST 
CENTRAL TEXAS ON THE EVENING OF THE 1ST. A COUPLE OF STORMS
OVER SOUTHERN SECTIONS PRODUCED SMALL HAIL. THE RAIN CONTINUED
INTO THE 2ND OVER MAINLY NORTHERN SECTIONS...AS THE STORM SYSTEM 
STALLED OVER WEST TEXAS. RAINFALL FROM THIS SYSTEM WAS HEAVIEST 
OVER THE HEARTLAND AND BIG COUNTRY...WHERE SCATTERED LOCATIONS 
RECEIVED FROM ONE HALF INCH TO 1.5 INCHES.   

THE FIRST FROST OF THE AUTUM SEASON OCCURRED ON THE EARLY
MORNING OF THE 4TH...AS A HIGH PRESSURE SYSTEM WITH COLD AIR
SETTLED OVER WEST CENTRAL TEXAS. A LIGHT FREEZE OCCURRED AT A
FEW LOCATIONS (INCLUDING BROWNWOOD...SONORA...AND JUNCTION)
WITH LOW TEMPERATURES AT OR SLIGHTLY BELOW 32 DEGREES. THE 
FIRST OCCURRENCE OF A LOW TEMPERATURE OF 32 DEGREES OR BELOW 
OCCURRED AT ABILENE ON THE 30TH...AND AT SAN ANGELO ON THE 12TH.
A LIGHT FREEZE AFFECTED MANY AREAS OF WEST CENTRAL TEXAS ON A 
FEW OCCASIONS DURING NOVEMBER.

A SIGNIFICANT AND WIDESPREAD HEAVY RAIN EVENT OCCURRED FROM THE 
13TH THROUGH THE 16TH. A STRONG STORM SYSTEM SLOWLY APPROACHED 
TEXAS FROM NORTHWESTERN MEXICO. A SERIES OF UPPER LEVEL 
DISTURBANCES MOVED INTO THE REGION AHEAD OF THE MAIN STORM 
SYSTEM...AND INTERACTED WITH ABUNDANT MOISTURE IN THE AREA. 
THIS RESULTED IN SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS 
WITH HEAVY RAINFALL. RAINFALL AMOUNTS FROM THIS EVENT OF 4 TO 
7 INCHES WERE COMMON. THE HEAVY RAIN CAUSED FLOODING OF 
ROADS IN CROCKETT AND KIMBLE COUNTIES. STREET FLOODING WAS
REPORTED IN COLEMAN...AND FLOODING WAS REPORTED ALONG THE
SAN SABA RIVER IN SAN SABA COUNTY. 

WITH THE WIDESPREAD COVERAGE OF HEAVY RAIN...A CONSIDERABLE
AMOUNT OF RUNOFF INTO AREA LAKES AND STREAMS OCCURRED. THIS
RESULTED IN MAJOR FLOODING ALONG THE LLANO RIVER NEAR 
JUNCTION...WHICH IMPACTED THE SOUTH LLANO STATE PARK WITH
EXTENSIVE LOWLAND FLOODING. MODERATE FLOODING OCCURRED ALONG 
THE LLANO RIVER NEAR MASON...AND ALONG THE SAN SABA RIVER AT 
SAN SABA. MINOR FLOODING OCCURRED ALONG THE COLORADO RIVER 
ABOVE SILVER. THE RUNOFF INCREASED THE WATER LEVELS ON THE 
AREA RESERVOIRS.

ANOTHER STRONG STORM SYSTEM BROUGHT SEVERE WEATHER AND 
ADDITIONAL RAIN TO WEST CENTRAL TEXAS. UPPER LEVEL 
DISTURBANCES MOVED INTO THE REGION AHEAD OF THE MAIN 
STORM SYSTEM AND BROUGHT ROUNDS OF RAIN AND THUNDERSTORMS.
THIS SYSTEM TRACKED A LITTLE FARTHER NORTH THAN THE PREVIOUS
STORM SYSTEM...AND THE MOISTURE WAS NOT AS PLENTIFUL. AS A 
RESULT THE RAINFALL WAS NOT AS HEAVY AS WITH THE PREVIOUS 
SYSTEM. RAINFALL AMOUNTS OF ONE HALF TO ONE INCH WERE COMMON 
WITH SCATTERED ONE TO TWO INCH AMOUNTS. A FEW SEVERE 
STORMS...WITH LARGE HAIL AND DAMAGING WINDS...MOVED RAPIDLY 
NORTHEAST ACROSS THE CONCHO VALLEY AND NORTHERN 
HEARTLAND...AS THE MAIN STORM SYSTEM TRACKED INTO THE 
REGION. THESE STORMS PRODUCED NICKEL SIZE HAIL IN SAN 
ANGELO AND ALBANY...PING PONG BALL TO GOLFBALL SIZE HAIL 
IN BROWN COUNTY. A 60 MPH WIND GUST WAS REPORTED IN PAINT 
ROCK...AND THE SAN ANGELO REGIONAL AIRPORT RECORDED A 51 
MPH GUST. WINDS TO 65 MPH DOWNED POWER LINES IN COLEMAN.

COLD AIR INVADED THE REGION ON THE 29TH...FOLLOWING A STRONG
COLD FRONTAL PASSAGE. AN UPPER LEVEL DISTURBANCE ON THE 
NIGHT OF THE 29TH BROUGHT A LITTLE RAIN TO THE SOUTHERN HALF 
OF WEST CENTRAL TEXAS. A LITTLE LIGHT SLEET AND SNOW FELL 
NORTH OF A LINE FROM SAN ANGELO TO BROWNWOOD...BUT ONLY 
TRACE AMOUNTS OCCURRED.
