   The severe weather threat for Severe Thunderstorm Watch 471
   continues.

   SUMMARY...A few damaging gusts may still occur with the stronger
   cells or line segments over the next few hours.

   DISCUSSION...Multicell clusters have aggregated into a linear
   complex across eastern OH into PA, while an MCS continues to decay
   while tracking eastward into eastern PA. The warm sector preceding
   these storms continues to destabilize. However, given residual
   static stability, it seems that an appreciable uptick in intensity
   with any ongoing storms is less likely, and that storms may have
   peaked in intensity over most locales. The one exception may be
   across southeastern PA, where a local increase in storm intensity
   was noted with cells encountering surface temperatures near 90 F.
   Nonetheless, while a few more strong/damaging gusts cannot be ruled
   out over the next few hours, the current thinking is that a
   downstream Severe Thunderstorm Watch issuance may not be needed
   unless an appreciable upward trend in storm intensity is somehow
   realized.
