CONCERNING...SEVERE THUNDERSTORM WATCH 333...

VALID 101206Z - 101300Z

LARGE HAIL/WIND DAMAGE THREAT WILL PERSIST PRIMARILY ACROSS SERN
PORTIONS OF WW0333 FOR THE NEXT HALF HOUR OR SO.

REGIONAL RADAR DATA SUGGEST THAT THE STRONGEST STORMS ARE SLOWLY
MOVING AND/OR DEVELOPING SWD INTO THE WARM SECTOR OVER SERN PORTIONS
OF WW033 FROM SZL TO 30-40 MILES NW OF COU. VEERING SWLY LLJ NOTED
IN PLAN VIEW VWP/PROFILER LOOP INDICATES THAT THE STRONGEST FORCING
FOR LARGE-SCALE ASCENT ASSOCIATED WITH WAA REGIME WILL CONTINUE TO
SHIFT EWD INTO WW034. THEREFORE...EXPECT THE THREAT OF ISOLATED
LARGE HAIL/WIND DAMAGE TO CONTINUE FOR THE NEXT HALF HOUR OR SO
