   AREAS AFFECTED...NERN MS/MUCH OF AL/WRN FL PANHANDLE
   
   CONCERNING...TORNADO WATCH 3...
   
   VALID 050913Z - 051015Z
   
   THREAT FOR TORNADOES AND DAMAGING WINDS TO PERSIST ACROSS PARTS OF
   NERN MS AND MUCH OF AL TO THE WRN FL PANHANDLE DURING THE EARLY
   MORNING HOURS.
   
   REGIONAL RADARS INDICATED A SQUALL LINE WITH EMBEDDED SUPERCELLS
   EXTENDING SWD THROUGH WRN AL FROM LAMAR COUNTY...WITH THE NRN PART
   OF THE LINE MOVING NEWD AT 40-45 KT.  DISCRETE STORMS HAVE ALSO
   DEVELOPED EAST OF THE SQUALL LINE ACROSS CENTRAL AND SRN AL FROM
   BIBB TO DALLAS TO CONECUH COUNTIES...WITH THESE STORMS MOVING NWD AT
   45-50 KT.
   
   EXTENSIVE AREA OF SURFACE PRESSURE FALLS FROM NERN MS TO CENTRAL AL/
   WRN GA IS MAINTAINING SELY SURFACE WINDS ACROSS MUCH OF AL AND
   ENHANCING LOW LEVEL SHEAR FOR STORM ROTATION AND CONTINUED TORNADO
   POTENTIAL.  IN ADDITION...RECENT DEVELOPMENT OF SURFACE PRESSURE
   RISE/FALL COUPLET EXTENDING RESPECTIVELY FROM SRN MS TO CENTRAL AL
   SUGGESTS THIS PORTION OF THE SQUALL LINE SHOULD MAINTAIN FASTER
   FORWARD SPEED AND ENHANCED DAMAGING WIND THREAT.
