CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 151757Z - 151900Z

ISOLATED STRONG TO SEVERE PULSE STORMS WILL CONTINUE TO DEVELOP FROM
FAR NRN AL/GA INTO MIDDLE/ERN TN AND CENTRAL/ERN KY TO FAR WRN
NC/SWRN VA.

STRONG SURFACE HEATING WITHIN A MOIST AIR MASS /SURFACE DEWPOINTS
MID-UPPER 60S/ HAS WEAKENED THE SURFACE BASED CINH SUFFICIENTLY FOR
THE RECENT INCREASE IN TSTM COVERAGE FROM FAR NRN AL THROUGH PARTS
OF MIDDLE/ERN TN AND SRN KY.  THIS REGION IS LOCATED DOWNSTREAM OF A
WEAK LOW-MID LEVEL MCV CENTERED OVER SWRN TN.  FORCING FOR ASCENT
EAST OF THIS FEATURE SHOULD AID IN SUPPORTING A CONTINUED GREATER
COVERAGE OF TSTMS ACROSS THIS REGION.  VERY WEAK DEEP LAYER SHEAR
WILL TEND TO PROMOTE PULSE-TYPE STORMS WITHIN THE MODERATELY
UNSTABLE AIR MASS...WITH ACTIVITY TRACKING NEWD WITHIN SWLY MEAN
FLOW REGIME.  STEEPENING LOW LEVEL LAPSE RATES SHOULD SUPPORT
ISOLATED STRONG WIND GUSTS AS THE PRIMARY THREAT THROUGH THE
AFTERNOON.
