CONCERNING...SEVERE THUNDERSTORM WATCH 416...

VALID 252102Z - 252230Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 416
CONTINUES.

SUMMARY...THE THREAT FOR SEVERE WEATHER CONTINUES ACROSS THE WATCH
AREA AS THUNDERSTORMS CONTINUE TO MOVE INTO A DEEPLY-MIXED BOUNDARY
LAYER AND UNSTABLE AIRMASS. THE MAIN THREAT CONTINUES TO BE FOR
ISOLATED DAMAGING WINDS.

DISCUSSION...ISOLATED TO WIDELY-SCATTERED THUNDERSTORMS CONTINUE TO
MOVE EAST ACROSS THE WATCH AREA...WITH A SLIGHT DECREASE IN OVERALL
INTENSITY AND COVERAGE NOTED OVER THE LAST HOUR. ADDITIONAL
THUNDERSTORM DEVELOPMENT IS EXPECTED TO BE SOMEWHAT LIMITED AS A
CIRRUS CANOPY OVERSPREADS THE AREA...AND SHOULD BE LIMITED TO ANY
OUTFLOW BOUNDARIES THAT EMERGE FROM THE LONGER-LIVED STORMS
CURRENTLY OVER FREDERICK COUNTY, MD AND CLARKE COUNTY, VIRGINIA. A
FEW ADDITIONAL STORMS MAY ALSO AFFECT THE NORTHERN PORTION OF THE
WATCH AREA AS STORMS MOVE EAST SOUTHEAST FROM SOUTHERN PA. THE MAIN
THREAT CONTINUES TO BE FOR STORMS THAT ARE APPROACHING THE
WASHINGTON D.C. METRO AREA THAT STILL HAVE THE POTENTIAL TO PRODUCE
BRIEF DAMAGING WIND GUSTS IN THE STRONGER DOWNDRAFTS.
