AREAS AFFECTED…CNTRL AND NRN AL
CONCERNING…SEVERE POTENTIAL…WATCH LIKELY
VALID 241243Z – 241445Z
STORMS ARE EXPECTED TO INCREASE DURING THE MORNING ACROSS CNTRL AND
NRN AL. PRIMARY INITIAL THREAT WILL BE LARGE HAIL AND DAMAGING
WIND…BUT THE THREAT FOR STRONG TORNADOES WILL INCREASE LATER THIS
MORNING AND ESPECIALLY THIS AFTERNOON.
THIS MORNING A WARM FRONT EXTENDS FROM SWRN GA THROUGH CNTRL AL INTO
NRN MS AND WRN AR. THIS BOUNDARY SEPARATES WARM MOIST GULF AIR WITH
LOW 70S DEWPOINTS AND MODERATE INSTABILITY IN THE WARM SECTOR FROM A
MODIFIED CP BOUNDARY LAYER TO THE NORTH. THE FRONT WILL LIFT NWD AS
AN INTENSE LOW-LEVEL JET DEVELOPS THROUGH THE LOWER MS VALLEY IN
RESPONSE TO AN EWD EJECTING SHORTWAVE TROUGH NOW OVER TX. STORMS
CURRENTLY MOVING OUT OF MS WILL INITIALLY POSE A THREAT FOR MAINLY
LARGE HAIL AND DAMAGING WIND. HOWEVER…AS THE BOUNDARY LAYER
CONTINUES TO MOISTEN AND DESTABILIZE…THE RISK FOR TORNADIC
SUPERCELLS WILL INCREASE GIVEN THE SIZE OF HODOGRAPHS /SRH AOA 400
M2/S2 ALONG THE STRENGTHENING LOW LEVEL JET.
