   AREAS AFFECTED...CNTRL/SERN AL AND WCNTRL/SRN GA
   
   CONCERNING...TORNADO WATCH 62...
   
   VALID 261923Z - 262100Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 62 CONTINUES.
   
   STRONGEST POTENTIAL FOR TORNADOES THROUGH LATE AFTERNOON WILL EXIST
   IN 30-60 MILE CORRIDOR EXTENDING FROM 25NE OF SELMA AL-LA GRANGE
   GA-20E MACON GA.  VERY LARGE HAIL AND DAMAGING WIND GUSTS CAN ALSO
   BE EXPECTED.
   
   DISCRETE CELLS...INCLUDING A FEW SUPERCELLS...CONTINUE TO GRADUALLY
   INTENSIFY OVER CNTRL/ECNTRL AL AND WCNTRL GA THIS AFTERNOON.  THIS
   WAS ALONG THE NRN FRINGE OF STEEP LOW-LEVEL LAPSE RATES AND AMID A
   STOUT WSW SFC-850 MB JET AXIS.  SO FAR...STORMS THAT HAVE EXHIBITED
   LOW-LEVEL ROTATION HAVE NOT PRODUCED REPORTED TORNADOES...POSSIBLY
   DUE TO WEAK DIRECTIONAL SHEAR IN THE LOWEST 1KM. 
   HOWEVER...SUSTAINED SUPERCELLS THAT WILL TRACK ALONG/S OF THE FRONT
   DRAPED ACROSS ECNTRL AL AND WCNTRL GA WILL BE EMBEDDED IN AT LEAST
   200 M2/S2 EFFECTIVE SRH OWING TO SUBSTANTIAL SPEED SHEAR.  IT IS IN
   THAT ZONE WHERE GREATEST POTENTIAL FOR TORNADIC STORMS WILL EXIST.
