315 AM CST THU JAN 6 2005

LOW CLOUDS HAVE BEEN SLOW TO CLEAR...AND STILL HAVE SEVERAL REPORTS OF
(MOSTLY LAKE ENHANCED) FLURRIES. POINT SOUNDINGS ACROSS FAR ERN
OK/NW AR SUGGEST FLURRIES/POSSIBLY -FZDZ EARLY THIS MORNING. WILL
INCLUDE THIS IN THE FORECAST...BUT DONT PLAN ON AN ADVISORY AT THIS
TIME.

EXPECT CLOUDS TO GRADUALLY CLEAR THIS MORNING...WITH SOME SUNSHINE
FOR THE AFTERNOON. TEMPS WILL STRUGGLE TO REACH THE 25-30 DEGREE
RANGE IN ALL BUT SE OK THOUGH...AS COLD SFC HIGH SLOWLY SLIDES ACROSS
THE FORECAST AREA.

SFC RIDGE SLIDES E TONIGHT...WITH WAA/ISENTROPIC LIFT KICKING IN
OVER NRN TX IN ITS WAKE. SHOULD SEE BULK OF PRECIPITATION DEVELOP TO
THE SE OF OUR FORECAST AREA...BUT ITS CLOSE ENOUGH TO WARRANT LOW
POPS OVER FAR SE OK LATE TONIGHT/EARLY FRIDAY. SFC TEMPS LOOK JUST
COLD ENOUGH FOR LIGHT FREEZING RAIN. DAY SHIFT WILL NEED TO TAKE
ANOTHER CLOSE LOOK AT THIS.

GFS APPEARS TO SHIFT SFC RIDGE TOO QUICKLY E BY FRIDAY NIGHT...WITH
ETA/GEM/ECMWF AND UKMET ALL KEEPING RIDGE OVER THE FORECAST AREA.
DID NOTE THAT 06Z MESOETA IS A BIT FASTER WITH THE RETURN FLOW...BUT
PLAN ON LEANING TOWARD THE COOLER 00Z MET NUMBERS FOR NOW.

NOT MANY CHANGES MADE TO THE EXTENDED. GOOD WARMING TREND IS IN
STORE...AS DEEP SLY/SWLY FLOW IS ESTABLISHED OVER THE SRN PLAINS.
