AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
418 AM CDT MON MAR 12 2012

.DISCUSSION...
VIGOROUS UPPER TROUGH THAT WAS THE DOMINANT PLAYER FOR THE REGION
OVER THE LAST SEVERAL DAYS IS MOVING INTO THE UPPER MS VALLEY THIS
MORNING. DRY AIR ALOFT BEHIND THE AXIS OF THE TROUGH...COMBINED
WITH A VERY MOIST BOUNDARY LAYER FROM THE RECENT RAINFALL...HAS
LED TO LOW CLOUDS AND AREAS OF FOG ACROSS THE CWA THIS MORNING. SO
FAR...VSBYS HAVE NOT BEEN MUCH OF A PROBLEM EXCEPT IN A FEW
ISOLATED LOCATIONS. THEREFORE...WILL HOLD OFF ON A DENSE FOG
ADVISORY FOR NOW. WILL CONTINUE TO MONITOR IN CASE CONDITIONS
DETERIORATE AS CIGS BELOW 500 FEET ARE WIDESPREAD AND IT WOULD NOT
TAKE MUCH FOR THEM TO LOWER AND FOG TO DEVELOP. LATEST RADAR
LOOPS ALSO INDICATE SOME SHWRS HAVE BEEN TRYING TO DEVELOP IN A
WEAK CONVERGENCE ZONE ACROSS THE ERN ZONES. THEREFORE...KEPT
SLIGHT CHANCE POPS IN THESE AREAS THROUGH 00Z TUESDAY.
OTHERWISE...ADVECTION OF A WARM AND MOIST GULF AIRMASS NORTHWARD
WILL LEAD TO RAPID RECOVERY TODAY WITH HIGH TEMPS EXPECTED TO BE
NEAR 80 DEGREES ACROSS MUCH OF THE CWA.

MOST OF THE NEXT 7 DAYS CAN BE GENERALLY CHARACTERIZED AS A
PERSISTENCE FORECAST. SWLY FLOW ALOFT WILL CONTINUE TO STREAM MID
LEVEL MOISTURE OVERHEAD WHILE SLY SFC WINDS PROVIDE PLENTY OF GULF
MOISTURE. THIS PATTERN TENDS TO BRINGS CONTINUED CHANCES FOR SHWRS
AND TSTMS. HOWEVER...NO MAJOR SFC BOUNDARIES WILL BE NEARBY TO
PROVIDE A FOCUS FOR CONVECTIVE INITIATION...SO IT MAKES IT QUITE
DIFFICULT TO NAIL DOWN WHERE THE BEST CHANCES FOR RAIN WILL BE EACH
DAY. THURSDAY AND SATURDAY APPEAR TO SUPPORT HIGHER PRECIP CHANCES
AS A COUPLE OF SHORTWAVE TROUGHS QUICKLY MOVE OVER THE REGION. IT
WILL BE VERY SPRING-LIKE WITH A WARM AND MOIST AIRMASS REMAINING
IN PLACE. MAX TEMPS ARE LIKELY TO REMAIN FAIRLY STEADY IN THE
UPPER 70S AND LOWER 80S AREAWIDE.

&&

.AVIATION...
WIDESPREAD IFR CIGS AND VISIBILITIES IN FOG WILL LINGER ACROSS MUCH
OF THE AREA THROUGH 15Z...THEN EXPECT GRADUAL CLEARING AS DRIER AIR
MOVES INTO THE REGION. VFR CONDITIONS WILL THEN PERSIST THROUGH
13/06. AFTER 06Z...BOUNDARY LAYER MOISTURE WILL RETURN FROM THE
SOUTH...SPREADING IFR CIGS AND VISIBILITIES NORTHWARD ACROSS THE
FOUR STATE REGION. THESE LOWERED FLIGHT CONDITIONS WILL PERSIST
BEYOND 13/12Z.  SURFACE WIND SOUTH AROUND 10 KTS TODAY AND 5 TO 10
KTS AFTER 13/00Z. /14/
