   AREAS AFFECTED...SOUTHEAST AL/MUCH OF GA
   
   CONCERNING...TORNADO WATCH 25...
   
   VALID 190158Z - 190330Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 25 CONTINUES.
   
   TORNADO WATCH 25 CONTINUES UNTIL 04Z ACROSS SOUTHEAST AL INTO MUCH
   OF CENTRAL/SOUTHWEST GA. THE TORNADO RISK SHOULD GRADUALLY DIMINISH
   OVER THE NEXT HOUR OR SO...WITH A CONTINUED THREAT FOR SEVERE
   HAIL/DAMAGING WINDS.
   
   A NUMBER OF STRONG/SEVERE TSTMS INCLUDING SUPERCELLS CONTINUE
   ESPECIALLY FROM EAST CENTRAL AL INTO NORTH CENTRAL/EAST CENTRAL
   GA...CENTERED ROUGHLY ALONG A WEST-EAST CORRIDOR ABOUT 25-50 MILES
   SOUTH OF INTERSTATE 20. SOME TORNADO THREAT WILL CONTINUE MAINLY IN
   THE SHORT TERM GIVEN AMPLE NUMBER OF ROTATING TSTMS WITHIN A RICH
   LOW LEVEL SRH ENVIRONMENT. HOWEVER...MODEST BOUNDARY LAYER MOISTURE
   WILL FAVOR STEADILY COOLING TEMPERATURES SUCH THAT THE NEAR-SURFACE
   LAYER WILL CONTINUE TO STABILIZE WITH INCREASING SURFACE BASED CINH.
   FURTHERMORE...IT WOULD SEEM LIKELY THAT STORMS SHOULD CONTINUE TO
   CONSOLIDATE AND LINEAR ORGANIZE OVER THE NEXT FEW HOURS AS THE
   UPSTREAM PREFRONTAL TROUGH/COLD FRONT BEGINS TO ACCELERATE ACROSS
   MS/AL/GA. IN ALL...THE TORNADO RISK SHOULD GRADUALLY SUBSIDE AND
   BECOME MUCH MORE ISOLATED IN NATURE...WHILE AMPLE DEEP LAYER/LARGELY
   UNDIRECTIONAL FLOW WILL NEVERTHELESS ACCOUNT FOR A RISK OF DAMAGING
   WINDS ALONG WITH SEVERE HAIL.
