AREAS AFFECTED...S CNTRL THROUGH E CNTRL AL AND WRN AND NW GA

CONCERNING...TORNADO WATCH 886...

VALID 290428Z - 290530Z

TORNADO WATCH 886 WILL BE ALLOWED TO EXPIRE AT 05Z. A LIMITED THREAT
OF SEVERE WEATHER MAY PERSIST BEYOND 05Z ACROSS SRN AND E CNTRL AL
THROUGH WRN AND NW GA. HOWEVER...OVERALL TREND SHOULD BE FOR THE
THREAT TO GRADUALLY DIMINISH WITH TIME. 

LATE THIS EVENING A LINE OF THUNDERSTORMS CONTINUES FROM NWRN GA
SWWD THROUGH S CNTRL AL. THE LINE WILL CONTINUE SLOWLY EAST THROUGH
ERN AL AND INTO WRN GA THE REMAINDER OF THE EVENING AND INTO THE
EARLY MORNING HOURS. LOW LEVEL SHEAR REMAINS STRONG ACROSS ERN AL
AND WRN GA N OF SURFACE BOUNDARY THAT EXTENDS FROM THE FL PANHANDLE
NWWD INTO SRN AL. SOME POTENTIAL STILL EXISTS FOR ORGANIZED STORM
STRUCTURES WITH ISOLATED DAMAGING WIND OR A BRIEF TORNADO WITHIN THE
LINE. HOWEVER...MOST STORMS ARE PROBABLY BECOMING INCREASINGLY
ELEVATED WITH TIME. THE PRIMARY LIMITING FACTOR FOR A MORE ROBUST
SEVERE THREAT APPEARS TO BE WEAK SURFACE BASED INSTABILITY WHICH
SHOULD BECOME INCREASINGLY MARGINAL AS THE BOUNDARY LAYER CONTINUES
TO COOL.
