   The severe weather threat for Severe Thunderstorm Watch 234
   continues.

   SUMMARY...More rapid thunderstorm intensification, and the evolution
   of an increasingly organized cluster of storms with the potential to
   produce damaging wind gusts, appears likely across eastern
   Pennsylvania into southeastern New York state through 4-6 PM EDT.

   DISCUSSION...Convection initiating across and northeast of the Blue
   Ridge has evolved into a narrow intensifying line of thunderstorms. 
   Although low-level flow is modest, deep-layer shear beneath 40-50 kt
   southerly 500 mb flow is strong.  North-northeasterly storm motions
   are allowing for modest easterly low-level inflow emanating from a
   moist boundary-layer, which has developed CAPE of 1500-2000 J/kg
   with continuing insolation.  This may allow for rapid further
   intensification and upscale convective growth during the next couple
   of hours, as mid-level flow trends more cyclonic and heights fall. 
   The evolution of an increasingly organized convective system is
   possible, which could pose a substantive increase in potential for
   damaging wind gusts as an associated surface cold pool and mid-level
   rear inflow strengthen.
