AREAS AFFECTED...EASTERN LA...SOUTHERN MS...FAR SOUTHWEST AL
CONCERNING...SEVERE THUNDERSTORM WATCH 344...
VALID 282253Z - 290100Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 344
CONTINUES.
SUMMARY...LOCALIZED STRONG GUSTS REMAIN POSSIBLE WITH A
NORTHWARD-MOVING LINE ACROSS SOUTHERN MISSISSIPPI AND FAR SOUTHWEST
ALABAMA, AND AN EASTWARD-MOVING CLUSTER ACROSS FAR SOUTHEAST
LOUISIANA. AN ADDITIONAL WATCH IS NOT EXPECTED.
DISCUSSION...A NORTHWARD-MOVING WEST/EAST-ORIENTED LINE THAT BEGAN
IN SOUTHEAST LA/MS HAS PROGRESSED ACROSS SOUTHERN MS INTO A BIT OF
SOUTHWEST AL. MEASURED WIND GUSTS HAVE ONLY REACHED 30-35 MPH AT
SEVERAL SITES AS THE LINE PASSED, GIVEN ITS ORIENTATION AND WEAK
LOW-LEVEL FLOW REGIME. MEANWHILE, THE NORTH/SOUTH-ORIENTED LINE
MOVING EAST IN SOUTHERN LA HAS WEAKENED ACROSS THE NORTHERN PORTION
AS IT IMPINGES ON THE CONVECTIVE OVERTURNED AIRMASS IN THE WAKE OF
THE MS LINE. ANY STRONG GUST POTENTIAL WITH THIS CLUSTER SHOULD BE
CONFINED TO NEAR-COASTAL PORTIONS OF SOUTHEAST LA WHERE A POCKET OF
MID 80S SURFACE TEMPERATURES PERSISTS.
