yoda Posted August 21, 2011 Share Posted August 21, 2011 DISCUSSION...THUNDERSTORMS WILL INCREASE IN COVERAGE/INTENSITY THIS AFTERNOON IN CONJUNCTION WITH CONTINUED DAYTIME HEATING...AND AS A MIDLEVEL TROUGH AND COLD FRONT MOVE EWD/SEWD ACROSS THE REGION. ADDITIONALLY...A SURFACE LEE TROUGH FROM NRN VA TO ERN PA/SE NY WILL HELP FOCUS THUNDERSTORM DEVELOPMENT. MODERATE-STRONG INSTABILITY /MLCAPE AOA 2000 J PER KG/ AND INCREASING VERTICAL SHEAR THROUGH THE AFTERNOON WILL BE FAVORABLE FOR STORMS TO PRODUCE DAMAGING WINDS AND LARGE HAIL. A COUPLE OF SUPERCELLS MAY ALSO DEVELOP THIS AFTERNOON NEAR THE LEE TROUGH...AND AN ISOLATED TORNADO WILL BE POSSIBLE WHERE LOW-LEVEL SHEAR WILL BE SOMEWHAT STRONGER.

Kmlwx Posted August 21, 2011 Author Share Posted August 21, 2011 I wonder if that Loudoun Co. cell might be a supercell contender. It seems pretty intense and maybe some ill defined mid level circulation. Not sure. Link to comment Share on other sites More sharing options...
