   The severe weather threat for Severe Thunderstorm Watch 605
   continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 605. Damaging gusts should remain the primary threat, though a
   couple more instances of severe hail may occur and a tornado cannot
   be ruled out.

   DISCUSSION...Multicell clusters and supercells, with a history of
   damaging gusts and up to golfball sized hail, remain in progress
   across western into central PA. Meanwhile, thunderstorms are
   gradually increasing in both coverage and intensity across eastern
   PA and in far northwestern OH. As such, multiple rounds of strong to
   severe thunderstorms should simultaneously progress across Severe
   Thunderstorm Watch 605 through the afternoon. The greatest (and most
   immediate) threat for severe storms remains with the western PA
   cluster, which may grow upscale into an MCS given possible cold pool
   mergers. Should this occur, a focused corridor of damaging gusts and
   perhaps a QLCS tornado may result over central PA. Otherwise, more
   discrete development over northern OH may progress toward the OH/PA
   border. Damaging gusts are possible, and an instance of large hail
   or a tornado cannot be ruled out with these storms. Finally, a
   couple of wet downbursts may accompany preceding storms to the east
   of the Appalachians.
