   Areas affected...the DelMarVa into southeast Pennsylvania and New
   Jersey

   Concerning...Tornado Watch 67...

   Valid 161914Z - 162045Z

   The severe weather threat for Tornado Watch 67 continues.

   SUMMARY...Some damaging wind and brief tornado threat will persist
   through the afternoon.

   DISCUSSION...A line of convection (with minimal lightning) continues
   from northern Virginia to south-central Pennsylvania. This line has
   had sporadic damaging wind reports and perhaps a tornado or two this
   morning into the early afternoon. Weak instability ahead of this
   line may maintain some isolated damaging wind/isolated tornado
   threat through the afternoon. The tornado watch will be cancelled in
   the wake of this line of storms. Some threat for damaging convective
   winds with the front this evening still persists, but will be
   handled with an additional watch later this evening if necessary.
