   Mesoscale Discussion 0729
   NWS Storm Prediction Center Norman OK
   0946 PM CDT Wed Jun 13 2018

   Areas affected...Eastern Pennsylvania...northern New Jersey...and
   extreme southeast New York

   Concerning...Severe potential...Watch unlikely 

   Valid 140246Z - 140345Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Cluster of strong to severe storms will continue to move
   east. After collaboration with WFO PHI, it has been decided a small
   weather watch will not be issued and any further threat will be
   handled by local warnings.

   DISCUSSION...The persistent cluster of strong storms in eastern
   Pennsylvania will continue to move southeast through the early
   overnight hours. This cluster has started to exhibit MCV type
   characteristics in the past hour which may lead to a continued
   tornado threat. In addition, the storms are moving into an
   increasingly rich low-level theta-e environment with dewpoints
   around 70 degrees which may also help the storms to persist. Given
   the small threat area, a watch will not be issued and any further
   threat will be handled by local office warnings.
