   The severe weather threat for Severe Thunderstorm Watch 249
   continues.

   SUMMARY...Convective line will continue to pose a threat for
   damaging wind gusts as it moves across eastern OH into adjacent
   northwest WV and western PA.

   DISCUSSION...Radar imagery now indicates a coherent convective line
   from northeast OH southwestward into southeast OH. Northern portion
   of the line which previously show forward-propagating
   characteristics has recently lost some of its intensity and forward
   speed. Even with this loss in intensity, KPBZ radar data still shows
   strong winds within this portion of the line entering southwest PA.

   Southern portion of the line has recently increased in intensity
   (shown by stronger updrafts) as cold pools amalgamate. Subtle
   signals exist within the latest radar imagery of a forward surge
   beginning within this portion of the line. Given the stronger
   updrafts and potential for stronger downbursts, this scenario seem
   plausible, which would result in a localized corridor of higher
   wind-damage potential.
