AREAS AFFECTED...NORTHERN LA INTO CENTRAL/SOUTHERN MS AND SOUTHWEST
AL
CONCERNING...SEVERE THUNDERSTORM WATCH 328...
VALID 260304Z - 260430Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 328
CONTINUES.
SUMMARY...SOME WIND-DAMAGE POTENTIAL WILL SPREAD SOUTHWARD LATE THIS
EVENING.
DISCUSSION...A QLCS AND RELATED OUTFLOW IS SURGING QUICKLY SOUTHWARD
ACROSS CENTRAL MS LATE THIS EVENING, WITH SOME SOUTHWARD
ACCELERATION ALSO RECENTLY NOTED ACROSS NORTHERN LA. WHILE MODERATE
TO STRONG BUOYANCY REMAINS IN PLACE IMMEDIATELY DOWNSTREAM INTO
SOUTHERN MS AND NORTHEAST LA, RELATIVELY WEAK LOW-LEVEL FLOW AND
DEEP-LAYER SHEAR MAY HAMPER ORGANIZATION ALONG THE SOUTHWARD-MOVING
QLCS SEGMENT WITH TIME. HOWEVER, GIVEN THE EXTENSIVE SURGING OUTFLOW
AND RATHER STRONG PRESSURE RISES (GREATER THAN 4 MB IN 2 HOURS), A
LOOSELY ORGANIZED QLCS MAY MOVE INTO PARTS OF SOUTHERN MS AND
SOUTHWEST AL WITH TIME, WITH A CONTINUED THREAT OF AT LEAST
LOCALIZED WIND DAMAGE. LOCAL WATCH EXPANSION AND/OR DOWNSTREAM WATCH
ISSUANCE MAY EVENTUALLY BE NEEDED, DEPENDING ON SHORT-TERM TRENDS.
