   CONCERNING...SEVERE THUNDERSTORM WATCH 530...532...
   
   VALID 282327Z - 290130Z
   
   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.
   
   UNTIL THEN...MODIFIED RUC SOUNDINGS SUGGEST MOST FAVORABLE
   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.
