   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 628
   CONTINUES.
   
   THREAT FOR ISOLATED DAMAGING WIND AND HAIL WILL PERSIST FOR ANOTHER
   HOUR OR TWO...BUT OVERALL TREND WILL BE FOR STORMS TO DECREASE IN
   INTENSITY. WW 628 WILL LIKELY BE ALLOWED TO EXPIRE AT 01Z.
   
   EARLY THIS EVENING WIDELY SCATTERED STORMS CONTINUE IN PRE-FRONTAL
   WARM SECTOR ACROSS ME WHERE LATEST OBJECTIVE ANALYSIS INDICATES MAX
   MLCAPE AROUND 1000 J/KG. STORMS ARE EMBEDDED WITHIN SWLY BULK SHEAR
   OF 30-35 KT...SUFFICIENT FOR UPDRAFT ROTATION AND BOWING SEGMENTS.
   DEEPER FORCING FOR ASCENT SHOULD DECREASE IN WAKE OF SHORTWAVE
   TROUGH LIFTING NEWD THROUGH SERN QUEBEC. THIS IN CONJUNCTION WITH
   NOCTURNAL COOLING WILL LIKELY RESULT IN A DECREASE IN THUNDERSTORM
   COVERAGE AND INTENSITY OVER THE NEXT COUPLE HOURS.
