AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
210 PM CST WED FEB 13 2013

.DISCUSSION...
LINGERING CLOUD COVER CONTINUES ACROSS MUCH OF THE REGION...WITH THE 
WEAKENING FRONTAL BOUNDARY MAKING ITS WAY THROUGH THE AREA. CLOUDS 
MAY BE SLOW TO CLR UNTIL THIS EVENING...WITH THE UPPER TROUGH AXIS 
OVER THE OH VALLEY AREA LIFTING TO THE NE. COOLER/DRIER AIR WILL BE 
STREAMING INTO THE CNTRL TN VALLEY FROM THE NW TONIGHT...WITH THE 
POSSIBILITY FOR SOME PATCHY FOG OVERNIGHT GIVEN THE SAT/WET GROUND. 
THERE MAY BE A SLIGHT RISK OF FREEZING FOG THU MORNING...MAINLY IN 
DRAINAGE/SHELTERED AREAS. ANY EARLY MORNING FOG SHOULD QUICKLY LIFT 
WITH THE ONSET OF THE DAYTIME HEATING...WITH TEMPS RECOVERING CLOSE 
TO SEASONAL TRENDS.

QUIET AND MORE SEASONAL LIKE WX CONDITIONS ARE STILL XPCTED FOR THE 
END OF THE WORK WEEK...AS STRONG HIGH PRESSURE OUT OF THE SRN PLAINS 
MOVES EWD ACROSS THE WRN/CNTRL GULF COAST REGION. HIGH PRESSURE WILL 
THEN TRANSLATE EWD TOWARD THE SRN ATLANTIC BASIN NEAR THE START OF 
THE WEEKEND PERIOD...THEREBY ALLOWING SOME MOISTURE TO WORK ITS WAY 
NWD/CLOSE TO THE AREA LATE FRI AS A REINFORCING COLD FRONT SWEEPS EWD
THROUGH THE REGION. THERE MAY STILL BE JUST ENOUGH MOISTURE ALONG THE
FRONT TO RESULT IN A FEW FLURRIES LATE FRI NIGHT/SAT...BEFORE DRIER
AIR WORKS BACK INTO THE AREA LATER IN THE DAY SAT. LATEST MODEL RUNS
THOUGH CONTINUE TO HINT AT THE PATTERN REMAINING MOSTLY DRY HEADING
INTO THE NEW WORK.

THIS SETS THE STAGE FOR YET ANOTHER STRONG AREA OF HIGH PRESSURE OUT 
OF THE SRN PLAINS MOVING EWD ALONG THE GULF REGION ON MON. LIKE THE 
FIRST HIGH PRESSURE SYSTEM...THIS ONE WILL ALSO QUICKLY MOVE TOWARD 
THE E WITH RETURN FLOW DEVELOPING BY TUE. THE OVERALL PATTERN THEN 
BECOMES FAIRLY PROGRESSIVE...WITH A SERIES OF UPPER LEVEL TROUGHS 
AND ASSOCIATED FRONTAL BOUNDARIES AFFECTING THE REGION. THIS FIRST 
ONE LOOKS TO IMPACT MUCH OF REGION LATE MON...WITH SCT/NUMEROUS 
SHOWERS COUPLED WITH EMBEDDED TSTMS DEVELOPING ALONG/AHEAD OF THE 
ADVANCING FRONT. STILL A LITTLE EARLY TO GET INTO THE SPECIFICS WITH 
THIS NEXT SYSTEM...ALTHOUGH THE DYNAMICS/SHEAR INITIALLY LOOK FAIRLY 
STRONG. THIS SYSTEM IS XPCTED TO SHIFT E OF THE AREA BY TUE...WITH 
ANOTHER STRONG DOME OF HIGH PRESSURE OUT OF THE NRN PLAINS BUILDING 
SWD INTO THE REGION.

MORE HOURS, LIFTING INTO THE VFR CATEGORY BY ~22-23Z. PATCHY -DZ OR

EVENING. ALTHOUGH NOT A CERTAINTY, CLEARING IS EXPECTED TO TAKE PLACE

LIGHT WINDS AND A CLEAR SKY WILL ALLOW FOR PATCHY RADIATION BR/FG TO
