   NWS STORM PREDICTION CENTER NORMAN OK
   1255 AM CST SUN MAR 01 2009
   
   AREAS AFFECTED...SERN GA...ERN SC...NRN FL
   
   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 
   
   VALID 010655Z - 010830Z
   
   AN ADDITIONAL WEATHER WATCH IS LIKELY FOR PARTS OF SERN GA...ERN SC
   AND NRN FL.  
   
   STRONGEST 2-HRLY PRESSURE FALLS HAVE BEEN CONCENTRATING ACROSS SERN
   GA NEWD INTO ERN SC AND THE 1008 MB LOW OVER SCNTRL GA SHOULD
   GRADUALLY INTENSIFY AS IT MOVES TO NEAR KSAV BY 12Z.  WARM SECTOR
   FROM NRN FL INTO ERN SC SHOULD CONTINUE TO MOISTEN AS 50+ KT SWLY
   LLJ TRANSLATES ERN GULF MOISTURE NWD.  THE MARGINAL INSTABILITY
   COUPLED WITH DRAMATICALLY INCREASING UVV ASSOCD WITH THE APCHG
   POS-TILT UPR LOW WILL KEEP THE RISK FOR TSTMS HIGH THROUGH
   MID-MORNING.
   
   GIVEN THE AVERAGE 59-63 DEG F SFC DEW POINT...RUC FCST SOUNDINGS
   SUGGEST THAT TSTMS WILL BE SLIGHTLY ELEVATED...BUT EFFECTIVE PARCELS
   BEING INGESTED WILL BE VERY NEAR THE SFC.  THUS...GIVEN THE 175-250
   M2/S2 0-1KM SRH EXPECTED...ISOLD TORNADOES CANNOT BE RULED
   OUT...PARTICULARLY FROM NERN FL NEWD ALONG THE CST OF GA/SC.  
   
   OTHERWISE...THE LOW/MID-LVL WIND FIELDS WILL BECOME MORE ALIGNED
   WITH TIME AS THE UPR LOW APCHS.  AS LEADING EDGE OF THE DEEP AND
   STRONG UVV CATCHES UP WITH THE PRIMARY CDFNT...A TREND TOWARD A QLCS
   IS EXPECTED THAT WILL SLOWLY SINK SEWD ACROSS ERN SC...SERN GA AND
   NRN FL.  EMPHASIS ON DMGG WIND GUSTS AND HAIL WILL INCREASE
   THEREAFTER...THOUGH AN ISOLD TORNADO CANNOT BE RULED OUT.
