   0247 AM CST SAT FEB 22 2003
   
   AREAS AFFECTED...NRN AL / NRN GA / SRN TN / SWRN NC / NWRN SC
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 220847Z - 221145Z
   
   SEVERE THREAT IS FORECAST TO INCREASE ACROSS THIS REGION OVER THE
   NEXT SEVERAL HOURS.  WW MAY BE REQUIRED SHORTLY ACROSS NRN AL /
   NRN GA.
   
   LATEST SURFACE ANALYSES CONFIRM MODEL FORECASTS OF SURFACE FLOW
   VEERING TO SLY ACROSS THIS REGION.  DEEP-LAYER WIND FIELD ACROSS
   THE REGION REMAINS FAVORABLE FOR SEVERE CONVECTION...BUT WEAK /
   ELEVATED NATURE OF INSTABILITY HAS LIMITED THE SEVERE THREAT THUS
   FAR.  
   
   HOWEVER...AS SLY LOW-LEVEL FLOW AND ASSOCIATED THETA-E ADVECTION
   INCREASES ACROSS THIS AREA...LOW-LEVEL STABLE LAYER SHOULD WEAKEN
   / BECOME SHALLOWER WITH TIME...THUS INCREASING THE THREAT FOR
   DAMAGING WINDS OR AN ISOLATED TORNADO.	MOST IMMEDIATE THREAT
   APPEARS TO EXIST ACROSS NRN AL AND INTO NWRN GA...BUT MAY SPREAD
   AS FAR N AS TN AND AS FAR E AS SWRN NC / NWRN SC TOWARD 22/12Z.
