.DISCUSSION...
WATER VAPOR SATELLITE IMAGERY SHOWS THE UPPER LEVEL LOW OVER BAJA
MOVING EAST. THE 3 AM SURFACE ANALYSIS INDICATED A STRONG COLD
FRONT EXTENDED FROM NEAR FORT SMITH ARKANSAS SOUTHWEST THROUGH
WICHITA FALLS TO CLOVIS NEW MEXICO. THIS FRONT WILL SWEEP THROUGH
THE FORECAST AREA TODAY...EXTENDING NEAR A PARIS TO CLEBURNE TO
COMANCHE LINE AROUND DAYBREAK AND MOVE THROUGH PALESTINE TO
KILLEEN EARLY TO MID AFTERNOON. EXPECT TEMPERATURES TO BE STEADY
OR SLOWLY FALL WITH THE INITIAL FRONTAL PASSAGE WITH A BIGGER DROP
A FEW HOURS THEREAFTER. THE FREEZING LINE SHOULD BE NEAR A
GAINESVILLE TO GRAHAM LINE BY MIDDAY AND EXTEND FROM NEAR PARIS TO
CLEBURNE AND BROWNWOOD BY SUNSET. THE FREEZING LINE SHOULD BE
THROUGH ALL BUT THE EXTREME SOUTHEASTERN COUNTIES BY MIDNIGHT
TONIGHT.

AS TEMPERATURES COOL...THE RAIN SHOULD CHANGE OVER TO FREEZING
RAIN AND SLEET THIS AFTERNOON STARTING IN THE NORTHWESTERN
COUNTIES...AND SPREADING TOWARD A PARIS TO DFW TO COMANCHE LINE BY
SUNSET. THERE WILL STRONG BROADSCALE LIFT ASSOCIATED WITH THE
AFOREMENTIONED UPPER LEVEL LOW TONIGHT. STRONG FRONTOGENETIC
FORCING ALOFT SHOULD ALSO RESULT IN THE DEVELOPMENT OF SOME
CONVECTION TONIGHT. THIS WILL INCREASE THE POTENTIAL FOR LOCALLY
HEAVY SLEET AND SNOW ACROSS THE NORTHWESTERN HALF OF THE FORECAST
AREA. THUS WE HAVE DECIDED TO UPGRADE THE WINTER WEATHER ADVISORY
TO A WINTER STORM WARNING ALONG AND NORTHWEST OF A GOLDTHWAITE TO
CANTON LINE. FREEZING RAIN AND SLEET ACROSS THE SOUTHERN PART OF
THE WARNING AREA MAY ALSO REACH CRITERIA. HAVE LEFT THE WINTER
WEATHER ADVISORY FOR THE SOUTHERN PART OF THE FORECAST AREA AS

FREEZING RAIN WILL BE THE MAIN ISSUE TONIGHT...WITH SOME LIGHT
SLEET AND SNOW POSSIBLE LATE TONIGHT INTO THURSDAY MORNING.
