VALID 241739Z - 241845Z

TSTMS HAVE FORMED IN THE PAST HOUR OVER WRN TN.  THIS ACTIVITY IS
DEVELOPING ON ERN EDGE OF WEAK COLD POOL/DIFFERENTIAL HEATING AREA
ASSOCIATED WITH WEAK VORT LOBE NOW EXTENDING FROM NEAR OWB SW TO
NEAR MEM.  STRONG HEATING THAT WILL OCCUR AHEAD OF VORT LOBE FROM NE
MS/NRN AL INTO S CNTRL KY SHOULD BOOST SBCAPE TO NEAR 2000 J/KG
LATER TODAY...LEADING TO ADDITIONAL STORM DEVELOPMENT AS LOBE
CONTINUES SLOWLY EWD.

WEAK LINEAR FORCING PROVIDED BY VORT LOBE...MODEST UNIDIRECTIONAL
SWLY SHEAR PARALLEL TO LOBE AND THERMODYNAMIC CONDITIONS MODERATELY
FAVORABLE FOR COLD POOL DEVELOPMENT SUGGEST THAT STORMS WILL EVOLVE
INTO A NE/SW ORIENTED LINE.  THIS LINE SHOULD MOVE GENERALLY E
THROUGH THE REMAINDER OF THE DAY AND MAY POSE A THREAT FOR LOCALLY
DAMAGING WIND AND HAIL BEFORE WEAKENING AS IT OVERTAKES MORE
ISOLATED ACTIVITY FORMING OVER THE HIGHER TERRAIN OF THE SRN
APPALACHIANS /REF MCS 1265/.
