   VALID 082000Z - 091200Z
   
   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF THE ERN
   MID-ATLANTIC REGION...
   
   ...NC OUTERBANKS/TIDEWATER VA/LWR MD SHORE/DE/SRN NJ...
   STRONGLY FORCED BANDS OF TSTMS CONTINUE TO RAPIDLY TRANSLATE NEWD
   ACROSS ERN PARTS OF VA/NC AND WILL MOVE INTO SERN PA...ERN MD...DE
   AND SRN NJ THROUGH LATE AFTN.  VWP FROM WAKEFIELD SAMPLED THE VERY
   STRONG WIND FIELDS WITH 55 KTS BLO 1/2KM...BUT WITH A DECIDEDLY
   UNIDIRECTIONAL SWLY REGIME.  AHEAD OF THE TSTM BANDS...A NARROW
   TONGUE OF UPR 50S-LWR 60S SFC DEW POINTS WILL BE MAINTAINED...
   BOOSTING MUCAPE INTO THE COUPLE HUNDRED J/KG RANGE.  GIVEN THE
   STRONG AMBIENT WIND FIELDS AND UNIDIRECTIONALITY TO THE FLOW
   REGIME...SMALL LINEAR BANDS MAY LOCALLY BOW AND BRING HIGHER
   MOMENTUM TO THE SFC.  THIS THREAT WILL DIMINISH THROUGH THE EVENING
   AS THE TSTMS APCH NYC AND SRN NEW ENGLAND.
   
   FARTHER W...TSTMS HAVE DEVELOPED ALONG THE PRIMARY COLD FRONT ALONG
   THE ALLEGHENY PLATEAU WHERE FRONTAL CIRCULATION WAS BEING ENHANCED
   BY VERY STRONG DCVA.  BOUNDARY LAYER DOWNSTREAM WAS RAPIDLY DRYING
   IN WAKE OF THE LEADING BANDS OF STORMS...LIMITING CAPE.  BUT...VSBL
   SATL DOES SHOW THAT THE BOUNDARY LAYER WAS WARMING WITHIN THE
   LOW-LVL DRY SLOT...SOMEWHAT COMPENSATING FOR THE LACK OF MOISTURE. 
   AS A RESULT...AN ISOLD DMGG WIND GUST MAY OCCUR AS THESE STORMS
   TRANSLATE ACROSS NRN VA...DISTRICT OF COLUMBIA...CNTRL/ERN MD AND
   SCNTRL/SERN PA.
