   DEVELOPING ON ERN EDGE OF WEAK COLD POOL/DIFFERENTIAL HEATING AREA
   ASSOCIATED WITH WEAK VORT LOBE NOW EXTENDING FROM NEAR OWB SW TO

   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
