DAMAGING WIND THREAT WILL CONTINUE OVER SERN LA/FAR SRN MS AND SWRN
AL AS A LARGE LINEAR MCS INTERACTS WITH DEVELOPING CONVECTION AHEAD
OF THE MCS...AND STORM MERGERS ENHANCE DOWNDRAFT POTENTIAL OVER THE
AREA.

21Z SFC ANALYSIS INDICATES A COLD POOL HAS DEVELOPED OVER SWRN
MS/NERN LA WITH 2 MB MEASURED RISE AT MACOMB MS IN THE LAST HOUR.
AIRMASS DOWNSTREAM OF THIS LINE REMAINS MODERATELY UNSTABLE WITH
MLCAPES FROMM 1500-2000 J/KG. AS LINE MOVES SSEWD AROUND 30 KTS OVER
THE NEXT FEW HOURS...MERGING WITH ADDITIONAL ISOLATED CONVECTION AND
OR REMNANT OUTFLOW BOUNDARIES FROM THIS CONVECTION OVER THE NEW
ORLEANS AREA AND OVER SWRN AL MAY LOCALLY ENHANCE UPDRAFT/DOWNDRAFTS
WITH INCREASED DAMAGING WIND THREAT. SEVERE THREAT SHOULD SUBSIDE IN
THE AREA AS LINE MOVES EITHER OFFSHORE OR DISSIPATES DUE TO LOSS OF
HEATING IN THE AREA BY AROUND 01Z.
