931 AM CST MON JAN 26 2009

...FREEZING RAIN POSSIBLE ACROSS PORTIONS OF WEST CENTRAL TEXAS
THIS AFTERNOON THROUGH WEDNESDAY...

A STRONG COLD FRONT IS CURRENTLY PUSHING THROUGH WEST CENTRAL
TEXAS THIS MORNING...AND WILL USHER IN A SHALLOW COLD AIR MASS
INTO MUCH OF WEST CENTRAL TEXAS THIS AFTERNOON. TEMPERATURES ARE
ALREADY IN THE UPPER 20S AND LOW 30S ACROSS MUCH OF THE BIG
COUNTRY...AND TEMPERATURES ACROSS THE CONCHO VALLEY AND HEARTLAND
ARE EXPECTED TO DROP INTO THE 30S THIS AFTERNOON. AN UPPER LEVEL
TROUGH IS ALSO DEVELOPING ACROSS THE SOUTHWEST UNITED STATES...AND
WILL BRING INCREASED CHANCES FOR PRECIPITATION ACROSS WEST CENTRAL
TEXAS THIS AFTERNOON THROUGH WEDNESDAY. AS THE SHALLOW COLD AIR
CONTINUES TO FILTER IN...WARMER...MOIST AIR WILL SURGE NORTH OVER
THE COLD AIR...CAUSING ANY RAINFALL THAT DOES DEVELOP TO FREEZE AS
IT FALLS INTO THE COLD AIR NEAR THE SURFACE.

AT THIS TIME...THERE ARE STILL SOME UNCERTAINTIES IN REGARD TO THE
LOCATION OF THE COLDEST AIR...AND THE AMOUNT OF MOISTURE AVAILABLE
TO PRODUCE PRECIPITATION. THE CURRENT FORECAST HAS THE SUBFREEZING
TEMPERATURES GENERALLY ALONG AND NORTH OF AN ELDORADO TO SAN SABA LINE TUESDAY MORNING...WITH TEMPERATURES IN THE MID 20S ACROSS THE BIG
COUNTRY...AND IN THE UPPER 20S TO LOW 30S ACROSS THE CONCHO VALLEY
AND HEARTLAND.

THE UPPER LEVEL TROUGH WILL PUSH EAST ACROSS THE SOUTHERN UNITED
STATES TUESDAY AFTERNOON...CAUSING THE SHALLOW COLD AIR TO SAG
FURTHER SOUTH INTO SOUTHERN TEXAS. THIS WILL CAUSE TEMPERATURES
ALONG THE INTERSTATE 10 CORRIDOR TO ALSO DROP INTO THE LOW 30S. AS A
RESULT...THE FREEZING LINE WILL PUSH FURTHER SOUTH TUESDAY NIGHT
INTO WEDNESDAY MORNING...AND WILL BE LOCATED GENERALLY SOUTH OF
INTERSTATE 10. FROZEN PRECIPITATION IS POSSIBLE ACROSS ALL OF WEST
CENTRAL TEXAS TUESDAY NIGHT INTO WEDNESDAY MORNING WITH ANY
PRECIPITATION THAT DOES FORM.

AREA RESIDENTS SHOULD BE PREPARED FOR POSSIBLE TRAVEL HAZARDS
STARTING MONDAY AFTERNOON THROUGH WEDNESDAY AS AREA ROADS MAY
BECOME SLIPPERY...ESPECIALLY BRIDGES AND OVERPASSES. STAY TUNED
TO NOAA WEATHER RADIO...LOCAL MEDIA...AND INTERNET SOURCES FOR THE
LATEST FORECASTS.
