   CORRECTED FOR AREA
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 887 CONTINUES.
   
   A BROKEN LINE OF STORMS FROM NRN AL TO THE GULF COAST CONTINUES TO
   SHOW AREAS OF ROTATION ON RADAR...AND THE ENVIRONMENT REMAINS
   FAVORABLE FOR A FEW TORNADOES. A NEW TORNADO WATCH WILL REPLACE
   WATCH 887.
   
   SURFACE ANALYSIS SHOWS A WEAK LOW OVER NRN AL...REFLECTED BY A
   RELATIVELY STRONG THUNDERSTORM CURRENTLY OVER MADISON COUNTY AL. W
   TO SWLY LOW LEVEL FLOW WILL CONTINUE TO BRING MOISTURE AND
   INSTABILITY SLOWLY NWD ACROSS THE REMAINDER OF NERN AL AND INTO NRN
   GA AS WELL. THUS...THE NEW TORNADO WATCH WILL LIKELY EXTEND A BIT
   FARTHER N THAN THE EXISTING WATCH.
   
   OTHER CELLS ARE MORE ROBUST OVER CNTRL AND SWRN AL...WHERE GREATER
   INSTABILITY IS PRESENT. THESE STORMS ARE LIKELY TO HAVE THE GREATEST
   TORNADO THREAT AS THEY CONTINUE ENEWD ACROSS AL AND INTO GA...WITH A
   BROAD WARM SECTOR IN PLACE WITH AMPLE DEEP LAYER SHEAR AND EFFECTIVE
   SRH FOR SUPERCELLS AND A FEW TORNADOES.
