AREAS AFFECTED...MUCH OF CNTRL AND NRN MS...SWRN TN...CNTRL AND NWRN
AL

CONCERNING...TORNADO WATCH 537...

VALID 131922Z - 132115Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 537 CONTINUES.

SUMMARY...THE SEVERE WEATHER THREAT IS EXPECTED TO INCREASE ACROSS
MUCH OF CNTRL AND NRN MS...SWRN TN...AND PERHAPS INTO AL.

DISCUSSION...A QLCS CONTINUES TO EVOLVE ACROSS THE MS RIVER WHERE
HEATING HAS CONTINUED TO DESTABILIZE THE AIR MASS. THIS LINE WILL
CONTINUE TO POSE A DAMAGING WIND/BRIEF TORNADO THREAT. IN
ADDITION...ISOLATED CELLS HAVE FORMED AHEAD OF THE MAIN LINE...WITH
A STRONG PROPENSITY TO BECOME SUPERCELLS. THESE NWD-MOVING CELLS ARE
IN A REGION OF CONCENTRATED PRESSURE FALLS PER LATEST SURFACE
ANALYSIS. ALSO...THE SHEAR PROFILES INTENSIFY WITH NWD EXTENT.
THEREFORE...IT IS EXPECTED THAT SOME OF THESE CELLS COULD STRENGTHEN
AND BECOME TORNADIC WITH EFFECTIVE SRH IN EXCESS OF 300 M2/S2 N OF
JACKSON MS.

TO THE E...A BATCH OF CELLS CONTINUES TO MOVE RAPIDLY NWD INTO CNTRL
AL. THE RAPID MOTION SUGGESTS IT MAY TAKE AWHILE FOR SOME OF THESE
STORMS TO CHANGE CHARACTER/SLOW DOWN IN SPEED AND TAKE ADVANTAGE OF
MORE FAVORABLE SR FLOW. THE WRN-MOST CELLS MAY HAVE A BETTER CHANCE
AT BECOMING SUPERCELLS AS THEY MOVE INTO A BETTER ENVIRONMENT.
