.DISCUSSION...

TONIGHT THROUGH THURSDAY NIGHT...

BREEZY CONDITIONS DEVELOPED AS EXPECTED TODAY WITH FULL SUN AND
STRONG MIXING RESULTING IN SUSTAINED WINDS NEAR 20 MPH AND GUSTS OF
30 TO 35 MPH...BUT WIND WILL DROP OFF AS WE COOL DURING THE LATE
AFTERNOON AND EARLY EVENING. A COLD FRONT WILL THEN MOVE ACROSS THE
ARKLAMISS TONIGHT AND BRING ANOTHER SURGE OF CHILLY AIR FOR
THANKSGIVING DAY THROUGH FRIDAY. COLD ADVECTION WILL KEEP WINDS UP
ENOUGH TONIGHT TO PREVENT TEMPERATURES FROM GETTING BELOW FREEZING.
WITH CLEAR SKIES AND SURFACE HIGH PRESSURE CENTERED OVER THE AREA
THURSDAY NIGHT...FAVORABLE NIGHTTIME COOLING CONDITIONS WILL BE IN
PLACE FOR TEMPERATURES TO DIP INTO THE MID/UPPER 20S AT MOST
LOCATIONS. AFTER A CHILLY THANKSGIVING DAY WITH HIGHS STRUGGLING TO
REACH THE UPPER 40S TO LOWER 50S...LOOK FOR SLIGHTLY WARMER HIGHS FOR
FRIDAY. /EC/

FRIDAY NIGHT THROUGH NEXT WEDNESDAY...THE SURFACE HIGH WILL SHIFT
EAST OF US FRIDAY AS THE UPPER LEVEL PATTERN OVER THE REGION BEGINS
TO BECOME MORE ZONAL OVER THE WEEKEND AND INTO EARLY NEXT WEEK.
MOISTURE WILL SUBTLY INCREASE ACROSS THE FORECAST AREA DURING THIS
TIME...WITH A GRADUAL WARMING TREND FOLLOWING SUIT THROUGHOUT THE
PERIOD.

THE GFS AND ECMWF NOW DIVERGE A BIT ON THEIR SOLUTIONS FOR EARLY
NEXT WEAK.  BOTH INDICATE A WEAK FRONT DROPPING SOUTH TOWARDS THE
FORECAST AREA MONDAY.  THE GFS REMAINS THE MORE RUN-TO-RUN
CONSISTENT OF THE TWO IN STALLING THIS FRONT NORTH OF THE REGION AND
EVENTUALLY WASHING IT OUT BY MID-WEEK.  THE ECMWF NOW STALLS THE
INITIAL FRONT OVER THE SOUTHERN HALF OF THE CWA TUESDAY.  THEN IT
BRINGS ANOTHER COLD FRONT THROUGH THE FORECAST AREA WEDNESDAY.  BOTH
SOLUTIONS BRING SOME RAIN CHANCES INTO THE FORECAST DURING THE
EXTENDED. /19/
