   Concerning...Severe Thunderstorm Watch 333...334...

   Valid 142052Z - 142245Z

   The severe weather threat for Severe Thunderstorm Watch 333, 334
   continues.

   SUMMARY...Severe threat continues within WW333 and WW334.

   DISCUSSION...A line of thunderstorms continues eastward along the
   cold front into portions of eastern Ohio into western Pennsylvania
   and southwestern New York this afternoon. Recent reports with this
   line have included gusts 50-60 mph and a brief tornado in Crawford
   County Pennsylvania. Just ahead of the approaching line, a favorably
   unstable air mass is noted in SPC Mesoanalysis, and observed by the
   18z RAOB from PIT. As this line continues eastward, potential for
   damaging winds will continue. Potential for a few isolated line
   embedded circulations will be greatest across portions of western PA
   where surface flow is remaining more southeasterly, enhancing
   low-level SRH. A few storms have developed ahead of the main line,
   which may warrant local extension of WW333 and WW334.
