AREAS AFFECTED...FAR ERN PA/NJ SWWD INTO ERN VA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 181724Z - 181900Z

POTENTIAL FOR ISOLATED DAMAGING WINDS OR HAIL WILL EXIST WITH MOST
INTENSE TSTMS THIS AFTERNOON. WW IS NOT ANTICIPATED.

TSTMS HAVE INCREASED IN COVERAGE AND INTENSITY OVER THE PAST HOUR
FROM PARTS OF ERN MD/DE SWWD INTO ERN VA WITHIN WEAKLY CAPPED AND
MODERATELY UNSTABLE AIRMASS /I.E. MLCAPES OF 1500-2000 J/KG/.
ADDITIONAL DEVELOPMENT CAN BE EXPECTED THROUGH THE REMAINDER OF THE
AFTERNOON ALONG AND E OF WEAK SURFACE TROUGH /EXTENDING FROM E OF
ABE TO NEAR CHO/...ESPECIALLY AS FORCING FOR ASCENT AHEAD OF WEAK
SHORTWAVE TROUGH CROSSING THE APPALACHIANS OVERSPREADS INSTABILITY
AXIS.

RELATIVELY WEAK WIND FIELDS OBSERVED ON REGIONAL VWPS SUGGESTS THAT
STORMS SHOULD REMAIN RATHER DISORGANIZED. POTENTIAL FOR ISOLATED
DAMAGING WINDS OR HAIL WILL EXIST WITH STRONGEST STORMS...HOWEVER...
GIVEN THE MODERATE INSTABILITY.
