Mesoscale Discussion 1429
   NWS Storm Prediction Center Norman OK
   0302 PM CDT Wed Jun 26 2024

   Areas affected...much of eastern Pennsylvania into New Jersey and
   southeast New York

   Concerning...Severe potential...Watch possible 

   Valid 262002Z - 262200Z

   Probability of Watch Issuance...40 percent

   SUMMARY...At least isolated severe gusts or marginal hail may occur
   this afternoon, with a greater potential for more widespread
   thunderstorms this evening.

   DISCUSSION...The air mass continues to destabilize south of an
   east-west oriented boundary from the PA/NY border eastward into
   southern New England. Visible satellite shows increase CU fields,
   with a few thunderstorms now extending from south-central PA into
   northern VA.

   As the main upper wave continues east, storms over northern PA along
   the front may organize further with damaging winds over much of
   northern PA possible. Isolated activity over southern PA has outflow
   associated with it currently, and this may support further
   development across the remainder of southeast PA, and eventually
   into NJ and southern NY. As such, the area is being monitored for
   further intensification or increase in coverage of the existing
   activity, and another watch may be considered over the next few
   hours south and/or east of WW 464.
