Area forecast discussion, Mar 21, 4:40 AM CDT, 4 hours 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
440 AM CDT WED MAR 21 2012

.DISCUSSION...
MOST OF THE ACTION IN THIS FORECAST PACKAGE IS IN THE FIRST 24 TO
48 HOURS. CUTOFF UPPER LOW HAS MOVED VERY LITTLE OVER THE LAST
SEVERAL HOURS. AS A RESULT...LINE OF CONVECTION IS NOT MAKING VERY
MUCH PROGRESS EWD. RAINFALL WILL CONTINUE OVER MUCH OF LOUISIANA
AND ADJACENT PORTIONS OF SW AR TODAY. RAINFALL AMOUNTS IN EXCESS
OF EIGHT INCHES...ALONG WITH NUMEROUS REPORTS OF FLOODING...HAVE
BEEN OBSERVED IN NATCHITOCHES PARISH. ADDITIONAL RAINFALL MAY LEAD
TO MORE FLOODING PROBLEMS TODAY. FARTHER WEST...MUCH OF E TX/SE
OK/EXTREME SW AR HAVE BEEN RAIN FREE SINCE THIS AFTERNOON. MORE
RAINFALL IS EXPECTED AND IS ALREADY APPROACHING THE AREA PER
LATEST RADAR LOOPS. HOWEVER...THIS ROUND OF RAIN SHOULD BE LIGHT.
SEVERE WX THREAT CONTINUES WITH THE MAIN CONVECTIVE BAND. OVERALL
INSTABILITY HAS DIMINISHED. HOWEVER...HIGH AMOUNTS OF LOW LEVEL
WIND SHEAR CONTINUE TO PRODUCE SHORT-LIVE SPIN-UPS WHERE UPDRAFTS
CAN BECOME MORE ORGANIZED AND SUSTAIN THEMSELVES.

PRECIP SHOULD BEGIN TO TAPER OFF FROM THE SW LATE THIS EVENING AS
PARTS OF THE CWA BECOME DRY SLOTTED AS THE UPPER TROUGH BEGINS TO
EJECT NE INTO OK. UPPER TROUGH WILL SLOWLY TRACK TOWARDS THE MID
MS VALLEY THROUGH THE REMAINDER OF THE WEEK. POSSIBILITY OF WRAP-
AROUND PRECIP WILL KEEP RAIN CHANCES IN THE FORECAST THROUGH THE
REMAINDER OF THE WORK WEEK ACROSS EXTREME NE TX/SE OK/SW AR.

UPPER LOW SHOULD FINALLY MOVE AWAY FROM THE AREA BY LATE FRIDAY
AND DRY WEATHER SHOULD RETURN AS AN UPPER RIDGE TAKES OVER.
REMAINDER OF THE FORECAST IS EXPECTED TO BE DRY THROUGH UNTIL THE
MIDDLE OF NEXT WEEK. TEMPS SHOULD BUILD BACK INTO THE 80S UNDER
THE INFLUENCE OF CLEAR SKIES AND THE UPPER RIDGE. /09/

&&

.AVIATION...
NORTH TO SOUTH AXIS OF MODERATE TO HEAVY RAINFALL BISECTING KMLU AND
KELD TERMINALS. EXPECT PREVAILING RAIN NEXT SVRL HOURS WITH OCNL
RUMBLE OF THUNDER. FURTHER WEST...BACK EDGE OF CONVECTION RIGHT
ALONG A KTXK TO KSHV LINE. SUPRISINGLY...STG TSTM CELL WILL MOVE
ACROSS THE KSHV TERMINAL BTWN 08-0830Z FROM THE SOUTH. SECONDARY
AREA WEAKER CONVECTION DEVELOPING WEST OF CWA...AND WILL LIKELY
REMAIN WEST OF KGGG...KTYR...AND KLFK. WEAK SFC LOW OVER NE TX
BRINGING LIGHT AND VRBL WINDS...WITH SE WINDS AROUND 10 KTS... WELL
TO THE EAST...BUT INCLUDING KMLU.  CEILINGS CONTINUE FLUCTUATING
FROM VFR TO MVFR...AND OCCASIONAL IFR. IFR VSBY AND CIGS MAY SET UP
OVER EAST TX SITES WHERE WINDS ARE LIGHT...GROUND IS WET...AND
AMBIENT CLOUDS IN MOSTLY MID LVL RANGE. VERY WET GROUND...AND CONTINUED
LOW LVL SOUTH FLOW ON BACKSIDE OF THIS SYSTEM....MAY SEE AREAS OF
FOG ACROSS MUCH OF THE REGION WED NIGHT./VII/.
