   CONCERNING...SEVERE THUNDERSTORM WATCH 352...
   
   VALID 241234Z - 241430Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 352
   CONTINUES.
   
   SEVERE TSTM WATCH 352 CONTINUES UNTIL 18Z...WITH A RISK OF SEVERE
   HAIL AND AN INCREASING POTENTIAL FOR DAMAGING WINDS THROUGH MID/LATE
   MORNING. CURRENT THINKING IS THAN AN ADDITIONAL WATCH WILL LIKELY BE
   NEEDED THIS MORNING FOR PORTIONS OF SOUTHERN WV AND VA/NORTHERN NC.
   
   A FORWARD PROPAGATING TSTM CLUSTER/MCS CONTINUES TO STEADILY
   PROGRESS EAST-NORTHEASTWARD ACROSS NORTHERN TN/SOUTHEAST KY EARLY
   THIS MORNING...AND ADDITIONAL UPSCALE GROWTH/EXPANSION OF THIS MCS
   SEEMS LIKELY THIS MORNING. SEVERE HAIL AND DAMAGING WINDS WILL
   REMAIN A CONCERN...WITH THE DAMAGING WIND POTENTIAL EXPECTED TO ONLY
   BECOME MORE WIDESPREAD THIS MORNING INTO A QUICKLY
   HEATING/DESTABILIZING BOUNDARY LAYER. ALONG THESE LINES...A MEASURED
   42 KT WIND GUST WAS RECENTLY NOTED AT MONTICELLO/EKQ IN KY. 
   
   CURRENT THINKING IS THAT AN ADDITIONAL SEVERE TSTM WATCH WILL LIKELY
   BE NEEDED FOR PORTIONS OF SOUTHERN WV AND WESTERN/SOUTHERN VA AND
   NORTHERN NC THIS MORNING...WHERE 12Z OBSERVED SOUNDINGS REFLECT
   STEEP LAPSE RATES ALOFT/POTENTIAL FOR AMPLE HEATING COINCIDENT WITH
   A BELT OF MODERATE WESTERLY FLOW ALOFT.
