AREAS AFFECTED...PORTIONS OF THE MID-ATLANTIC REGION

CONCERNING...SEVERE THUNDERSTORM WATCH 372...377...378...

VALID 302015Z - 302215Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
372...377...378...CONTINUES.

SUMMARY...THE RISK FOR SVR TSTMS CONTINUES ACROSS THE SEVERE
THUNDERSTORM WATCH AREAS.

DISCUSSION...SCATTERED CONVECTION CONTINUES FROM PARTS OF ERN PA TO
CNTRL NC WITHIN A BROAD ZONE OF 500-1500 J/KG OF MLCAPE. AREA VWPS
SUGGEST THAT 25-40 KT OF DEEP SHEAR WILL CONTINUE TO FOSTER
ORGANIZED CONVECTIVE STRUCTURES...AND POSSIBLY A FEW TRANSIENT
SUPERCELLS -- ESPECIALLY IN NRN PARTS OF THE MID-ATLANTIC /PA AND
NJ/ WHERE SFC WINDS ARE SLIGHTLY MORE BACKED ENHANCING LOW-LEVEL
SRH. ISOLATED TO WIDELY SCATTERED DMGG WIND GUSTS AND PERHAPS HAIL
WILL BE THE MAIN CONCERNS...THOUGH A BRIEF TORNADO CANNOT BE RULED
OUT IN ERN PA AND NJ. SFC SLY/SSELY FLOW WILL CONTINUE TO FOSTER
INLAND INFLUXES OF OCEAN-MODIFIED AIR WITH WEAKER BUOYANCY --
PROBABLY RESULTING IN SOME WEAKENING OF CONVECTION AS IT NEARS THE
COAST.
