MESOSCALE DISCUSSION 1037
NWS STORM PREDICTION CENTER NORMAN OK
1218 PM CDT SAT MAY 28 2005

AREAS AFFECTED...EXTREME NRN VA...SERN PA...SRN NJ...DE...CNTRL MD
AND DISTRICT OF COLUMBIA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 281718Z - 281845Z

DAMAGING WIND/HAIL THREATS WILL INCREASE ACROSS THE REGION THROUGH
THE AFTN.  
  
RADAR LOOPS/WATER VAPOR INDICATE A MID-LEVEL SHORTWAVE TROUGH MOVING
ACROSS CNTRL PA...WITH THE TAIL-END MOVING ACROSS NRN VA.  THOUGH
MOST OF CNTRL PA/WRN MD IS STABLE GIVEN LARGE SHIELD OF RAIN...
BOUNDARY LAYER HAS HEATED CONSIDERABLY DOWNSTREAM FROM NRN VA INTO
SERN PA.  ENHANCED FORCING FOR LARGE SCALE ASCENT ASSOCIATED WITH
THE WAVE AND INCREASING INSTABILITY HAVE CONTRIBUTED TO A CLUSTER OF
TSTMS FROM CNTRL MD INTO NRN VA.

THOUGH THERMAL BUOYANCY WILL REMAIN LOW...COMBINATION OF HIGH DEW
POINT DEPRESSIONS IN THE SUB-CLOUD LAYER AND STRONG UNIDIRECTIONAL
WSWLY FLOW REGIME WILL BE FAVORABLE FOR TSTM LINE SEGMENTS TO BOW
AND GIVE DAMAGING WINDS.  HIGHEST THREAT APPEARS TO BE NORTH OF
BALTIMORE...ACROSS SERN PA AND INTO PARTS OF SWRN NJ THROUGH 21Z.
