AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
223 PM CST SAT DEC 20 2014

.DISCUSSION...
CLOUD COVER AND TEMP PATTERN TODAY WILL MAKE FOR POSSIBLE ERRATIC
FOG DEVELOPMENT OVERNIGHT. DEWPOINT SPREADS NARROW TO THE NORTH OF
I-30...WHILE ERODING CLOUDS FROM THE EAST MIGHT ALSO MAKE FOR GOOD
RADIATION COOLING OVERNIGHT. GROUND STILL DAMP MOST OF
REGION....BUT LIGHT EASTERLY WINDS MAY CONTINUE OVERNIGHT. FOG
COULD BE DENSE...OR NOT AT ALL...SO WILL SIMPLY GO PATCHY FOG AREAWIDE.
WARMING TREND NEXT COUPLE OF DAYS WITH GRADUALLY INCREASING
SOUTHERLY FLOW...POSSIBLY EVEN APPROACHING LWA CRITERIA MONDAY
AFTN AS UPPER TROUGH MOVG EASTWARD TOWARDS AREA BEGINS TO DEEPEN.
AS HAS BEEN THE CASE LATELY...INSTABILITY WILL BE IN QUESTION AND
WILL SEE A MIX OF STRATIFORM AND CONVECTION....WITH ANY TSTMS
MOST LIKELY NEAR FROPA LATE MONDAY NIGHT INTO TUESDAY...AND
CONFINED TO REGIONS SOUTH OF I-20.

MOST OF AREA WILL BE SPARED FROM FRZG TEMP BEHIND THIS FRONT...AS
GFS INDICATES DEFINED WRAPAROUND CLOUDS MOVG BACK IN AFTER
MIDNIGHT...ALTHOUGH SOME PORTIONS OF SE OK/SW AR MAY DIP TO JUST
AROUND FRZG MARK. A QUICK TURAROUND TO SOUTHERLY WINDS FOR THE
LATTER PART OF THE WEEK WILL BRING TEMPS BACK TO SEASONALLY WARM.
HOWEVER...AN EVEN STRONGER COLD FRONT WILL SWEEP ACROSS THE ENTIRE
CWA FOR NEXT WEEKEND./VII/.
