Severe Storm Watch Until 9pm EST

MESOSCALE DISCUSSION 1725
NWS STORM PREDICTION CENTER NORMAN OK
1134 AM CDT TUE JUL 08 2008

AREAS AFFECTED...CENTRAL AND ERN VA/ERN HALF OF NC/NERN SC

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 081634Z - 081800Z

MARGINAL SEVERE THREAT ACROSS THIS REGION MAY WARRANT WW ISSUANCE.

DAYTIME HEATING CONTINUES ACROSS THE MD AREA EARLY THIS
AFTERNOON...NEAR AND JUST AHEAD OF THE UPPER CIRCULATION CENTER AND
ASSOCIATED POCKET OF COOLER AIR/STEEP LAPSE RATES ALOFT. THIS
COMBINED WITH A VERY MOIST BOUNDARY LAYER HAS RESULTED IN THE
DEVELOPMENT OF 1500 TO 2500 J/KG MIXED-LAYER CAPE.

WHILE DEEP-LAYER WIND FIELD IS NOT PARTICULARLY STRONG...DEGREE OF
SHEAR COMBINED WITH FAVORABLE THERMODYNAMIC ENVIRONMENT SUGGESTS
THAT MULTICELL STORMS -- AND AN ASSOCIATED THREAT FOR HAIL AND
LOCALLY-GUSTY/DAMAGING WINDS -- WILL PERSIST THROUGH THE AFTERNOON.
AS STORMS INCREASE IN COVERAGE...WW MAY BE REQUIRED.
