THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
530...532...CONTINUES.

WIDELY SCATTERED TSTMS OVER WW AREA...FROM ERN TN ACROSS ERN AL/WRN
GA AND CENTRAL MS...STILL MAY PRODUCE OCCASIONAL DAMAGING GUSTS NEAR
SVR LIMITS FOR ANOTHER COUPLE OF HOURS. A FEW MORE TSTMS MAY
DEVELOP...PRIMARILY BEFORE SUNSET ALONG INTERSECTIONS OF OUTFLOW
BOUNDARIES...WITH BRIEF/LOCALIZED POTENTIAL FOR DAMAGING DOWNBURSTS.
 HOWEVER...GENERAL TREND WILL BE TOWARD LESSER CONVECTIVE COVERAGE
AND MORE LOCALIZED/MRGL SVR POTENTIAL THROUGH REMAINDER LATE
AFTERNOON/EVENING...GIVEN COMBINED STABILIZING EFFECTS FROM
1. EVER-EXPANDING OUTFLOW POOLS PRODUCED BY EARLIER ACTIVITY...AND
2. DIABATIC SFC COOLING AND RELATED INCREASE IN MLCINH AFTER 00Z.

THEREFORE...REMAINING PORTIONS WWS SHOULD BE ALLOWED TO EXPIRE AS
SCHEDULED.

JUXTAPOSITION OF PARAMETERS SUPPORTING SVR POTENTIAL WILL SURROUND
ONGOING ACTIVITY OVER NERN THROUGH E-CENTRAL AL...WITH 2000-3000
J/KG MLCAPE THROUGH ABOUT 01Z...AND 25-35 KT EFFECTIVE SHEAR
MAGNITUDE IN SUPPORT OF MULTICELLULAR ORGANIZATION.
