   Concerning...Severe Thunderstorm Watch 322...

   Valid 122033Z - 122200Z

   The severe weather threat for Severe Thunderstorm Watch 322
   continues.

   SUMMARY...Isolated damaging wind gusts will remain possible for
   another couple of hours across Severe Thunderstorm Watch 322.

   DISCUSSION...Widely scattered thunderstorms are ongoing across
   portions of northeastern Pennsylvania into southeastern New York,
   with a dominant storm mode of multicell clusters. One of these
   clusters recently produced two reports of wind damage in Susquehanna
   County, PA. Latest objective analysis suggests that available
   buoyancy has increased to around 2000 J/kg MLCAPE with low-level
   lapse rates steepening to 7.5-8.0 C/km amid continued afternoon
   heating. Coupled with 25-30 kts of westerly mid-level flow sampled
   by the DIX/OKX VWPs, this will continue to support a risk for
   occasional damaging wind gusts with the ongoing multicell clusters.
   Convective intensity is then expected to gradually wane later this
   evening owing to nocturnal low-level cooling/stabilization.
