FORECAST STILL LOOKING GOOD. JUST A COUPLE OF SMALL TWEAKS TO THE
PACKAGE TO INCREASE RAINFALL QPF OVER THE COASTAL COUNTIES AND
INCREASE CLOUD COVER TODAY. TEMPERATURES IN THE NORTHWEST SHOULD
HAVE HIT THEIR HIGHS AND SHOULD BE A SLIDE DOWN FROM HERE AS THE
PRECIPITIATION (WHICH HAS SOME SLEET MIXED INTO IT) EXPANDS EAST.
HAVE ALREADY SEEN THE REPORT OF ONE HALF INCH OF SLEET/SNOW IN
PALESTINE AND 2" IN KILLEEN. THIS HEAIVER PRECIP/SNOW SHOULD START
TO SPREAD INTO THE NORTHWEST COUNTIES THE NEXT COUPLE OF HOURS. DID
ADD THE MENTION OF SLEET TO THE PACKAGE TODAY.
REST OF THE PACKAGE LOOKS ON TRACK AND SO NO CHANGES.

AT LEAST THREE WEATHER SYSTEMS WILL AFFECT SOUTHEAST TEXAS OVER
THE NEXT SEVEN DAYS. THE FIRST WILL BRING A VARIETY OF WINTER
WEATHER TODAY AND TONIGHT...THEN NEXT WILL AFFECT THE AREA
FRIDAY...AND THE THIRD SYSTEM EARLY NEXT WEEK.
FOR TODAY...THE LATEST WATER VAPOR SHOWED THE SHORTWAVE TROUGH
BEGINNING TO AFFECT THE STATE. LIGHT RAIN WAS APPROACHING THE
NORTHERN COUNTIES OF THE FORECAST AREA AT THIS HOUR. THE MAIN
ISSUES ARE WHEN SNOW WILL BEGIN...HOW MUCH CAN BE EXPECTED...AND
WHEN WILL THE PRECIPITATION END. THE LATEST MODELS WERE TRENDING
EARLIER AND A BIT DRIER THAN PREVIOUSLY FORECASTED. NAM AND GFS
BUFR FORECAST SOUNDINGS INDICATED THAT CONDITIONS WILL BE
CONDUCIVE FOR UP TO ABOUT 6 HOURS OF SNOW FALL IN COUNTIES COVERED
BY THE WINTER STORM WARNING. TO THE SOUTH OF THESE LOCATIONS...
MOST OF THE COLUMN WILL BE COLD ENOUGH FOR SNOW. HOWEVER...THE
LOWEST 1500 FEET OR SO WILL STAY ABOVE FREEZING UNTIL THIS
EVENING. THIS WOULD MEAN THAT THE NEAR SURFACE CONDITIONS SHOULD
REMAIN TOO WARM AND LITTLE IF ANY SNOWFALL ACCUMULATIONS CAN BE
EXPECTED MAINLY ALONG AND SOUTH OF THE INTERSTATE 10 CORRIDOR.
FOR THE SYSTEM ON FRIDAY...DID NOT CHANGE MUCH OF THE CURRENT
FORECAST. THE LATEST GFS INDICATES THAT THE RAIN MAY END EARLIER
ON FRIDAY THAN NOW FORECAST. THE THIRD SYSTEM EARLY NEXT WEEK
OCCURS IN A PATTERN THAT IS RATHER SIMILAR TO EARLY THIS WEEK. AT
LEAST WE CAN EXPECT A COLD RAINY PATTERN TO BEGIN SUNDAY AND END
BY TUESDAY. WILL NEED TO STAY TUNED AS TO THE MODEL TRENDS ON HOW
COLD THE AIRMASS COULD GET.
