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.
