AREAS AFFECTED...PORTIONS OF SRN/ERN LA AND SRN/WRN MS

CONCERNING...TORNADO WATCH 204...

VALID 242203Z - 250000Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 204 CONTINUES.

SUMMARY...THE THREAT FOR A COUPLE OF TORNADOES AND LOCALLY DAMAGING
WIND GUSTS CONTINUES ACROSS THE WW.

DISCUSSION...ACROSS WW 204...NUMEROUS CONVECTIVE CELLS HAVE EVOLVED
AHEAD OF A BROKEN BAND OF STRONG-TO-SEVERE TSTMS / ASSOCIATED LINE
OF CONFLUENCE STRETCHING FROM SERN AR SWD TO S-CNTRL LA. MANY OF
THESE CELLS HAVE EXHIBITED WEAK ROTATION...AND THE SEVERE POTENTIAL
IS LIKELY TO BE MAINTAINED OR BOLSTERED SOME OVER THE NEXT FEW
HOURS...AS FCST SOUNDINGS INDICATE BACKING OF THE WINDS IN THE
LOWEST 1-KM THROUGH 01Z. IN TURN...EFFECTIVE SRH VALUES ARE EXPECTED
TO BE ENHANCED SOME OVER THE NEXT FEW HOURS. IN COMBINATION WITH
VERY RICH LOW-LEVEL MOISTURE /E.G. MEAN MIXING RATIOS UPWARDS OF
15-16 G PER KG/ AND SOME INSOLATION AHEAD OF THE AXIS OF
CONFLUENCE...THIS WIND PROFILE SHOULD CONTINUE TO SUPPORT A
POTENTIAL FOR A COUPLE OF TORNADOES AS WELL AS SOME DAMAGING WIND
GUSTS.
