AREAS AFFECTED...ECNTRL AND SERN LA THROUGH SRN AND CNTRL MS

CONCERNING...TORNADO WATCH 32...

VALID 101959Z - 102130Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 32 CONTINUES.

SUMMARY...GREATEST TORNADO THREAT NOW THROUGH 22Z APPEARS TO BE
EVOLVING FROM ACROSS SRN MS. OTHERWISE...THREAT FOR DAMAGING WIND
AND TORNADOES WILL PERSIST OVER THE REMAINDER OF WW 32 FROM ECNTRL
AND SERN LA INTO SRN AND SCNTRL MS.

DISCUSSION...NUMEROUS DISCRETE STORMS ARE DEVELOPING WITHIN ZONE OF
WARM ADVECTION AND ISENTROPIC ASCENT ALONG LLJ AXIS FROM SERN LA
INTO SRN MS. STORMS NEAR AND SOUTH OF WARM FRONT ARE SURFACE BASED
AND HAVE ACCESS TO MOIST AND UNSTABLE LOW LEVEL INFLOW WHERE
DEWPOINTS ARE IN THE UPPER 60S AND TEMPERATURES IN THE LOW 70S. VWP
DATA SHOW VERY LARGE HODOGRAPHS ASSOCIATED WITH THE LLJ WITH 400-500
M2/S2 STORM RELATIVE HELICITY. THE DISCRETE STORMS IN SRN MS
CONTINUE TO BECOME BETTER ORGANIZED AS SUPERCELLS AND TORNADOES
APPEAR LIKELY WITH ACTIVITY DEVELOPING NEAR AND SOUTH OF THE WARM
FRONT. THIS BOUNDARY WILL CONTINUE LIFTING SLOWLY NWD DURING THE
REMAINDER OF THE AFTERNOON SUGGESTING THE ENHANCED TORNADO THREAT
WILL EXPAND NWD AND EWD WITH TIME. OTHER STORMS FARTHER WEST WITHIN
THE LINE WILL ALSO POSE A THREAT FOR DAMAGING WIND AND TORNADOES.

0239 PM CST SUN FEB 10 2013

AREAS AFFECTED...EXTREME SERN MS THROUGH SWRN AND SCNTRL AL

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 102039Z - 102145Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...THE THREAT FOR A FEW TORNADOES AND DAMAGING WIND IS
EXPECTED TO INCREASE THROUGH THE EARLY EVENING FROM EXTREME SERN MS
INTO SWRN AND SCNTRL AL. A WW WILL LIKELY BE NEEDED BEFORE 22Z.

DISCUSSION...A WARM FRONT EXTENDS FROM THE BOOT HEEL OF MS NWWD INTO
THE CNTRL PORTIONS OF SRN MS. NUMEROUS STORMS ARE DEVELOPING ACROSS
SWRN AL WHERE A 50 KT SSWLY LLJ IS AUGMENTING ISENTROPIC ASCENT NE
OF THIS BOUNDARY. THESE INITIAL STORMS ARE LIKELY ELEVATED ABOVE A
SHALLOW NEAR SURFACE STABLE LAYER THAT RESIDES NORTH OF THE WARM
FRONT. HOWEVER...RICHER GULF MOISTURE WITH AT LEAST MID 60S
DEWPOINTS WILL CONTINUE ADVECTING NEWD ALONG THE LLJ
AXIS...CONTRIBUTING TO BOUNDARY LAYER DESTABILIZATION INTO THE
EVENING. LARGE LOW LEVEL HODOGRAPHS AND STRONG EFFECTIVE SHEAR WILL
PROMOTE A THREAT OF SUPERCELLS AND BOWING SEGMENTS WITH TORNADO
THREAT LIKELY TO INCREASE LATER THIS AFTERNOON INTO THE EVENING WITH
THE EROSION OF THE NEAR SFC STABLE LAYER.
