   Concerning...Tornado Watch 54...

   Valid 161807Z - 161900Z

   The severe weather threat for Tornado Watch 54 continues.

   SUMMARY...A line of storms producing damaging winds continues to
   move rapidly east across Pennsylvania.

   DISCUSSION...A line of storms has produced widespread damaging wind
   gusts across West Virginia and western Pennsylvania this morning and
   early afternoon with occasional large hail. Expect the damaging wind
   and perhaps a brief tornado threat to continue through the afternoon
   given the presence of weak instability (100-250 J/kg) and strong
   lower tropospheric flow (70 knots at 1km per CCX VWP) ahead of these
   storms. Eventually expect this line to weaken across eastern
   Pennsylvania given widespread cloud cover. This will prevent further
   destabilization, particularly as the boundary layer begins to cool
   by early evening.
