   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.
