VALID 031527Z - 031700Z
REMNANT MCV OVER SRN OH IS PROGRESSING EWD AT ROUGHLY 35KT TOWARD
NRN WV/SWRN PA. ALONG THE LEADING EDGE OF THIS FEATURE OVERNIGHT
CONVECTION DID NOT COMPLETELY DISSIPATE AND WILL SOON BEGIN TO
INTENSIFY OVER THE HIGHER TERRAIN OF WV WHERE BOUNDARY LAYER HEATING
WAS MAXIMIZED FOR A FEW HOURS THIS MORNING. LATEST DIAGNOSTIC DATA
SUGGESTS SFC-3KM LAPSE RATES HAVE STEEPENED TO NEAR 8 C/KM FROM THE
ERN SLOPES OF THE CNTRL APPALACHIANS...NEWD INTO NJ. THIS AXIS OF
STRONG HEATING WILL CONTRIBUTE TO FURTHER DESTABILIZATION AND
THUNDERSTORMS SHOULD EASILY DEVELOP AHEAD OF AFOREMENTIONED MID
LEVEL FEATURE. VERTICAL SHEAR PROFILES WOULD SEEM TO SUPPORT A
THREAT OF ORGANIZED MULTI-CELLL UPDRAFTS CAPABLE OF PRODUCING
DAMAGING WINDS AND HAIL BY EARLY AFTERNOON. SEVERE THUNDERSTORM
WATCH WILL LIKELY BE ISSUED BY 17Z.
