   Areas affected...eastern PA/MD...DE and NJ

   Concerning...Severe Thunderstorm Watch 393...394...

   Valid 222055Z - 222230Z

   The severe weather threat for Severe Thunderstorm Watch 393, 394
   continues.

   SUMMARY...Locally damaging wind gusts will continue this afternoon
   into early evening as storms track eastward out of WW 393 and into
   WW 394.

   DISCUSSION...Clusters of strong to severe thunderstorms extended
   from near Northampton County in PA southward along the western banks
   of the Chesapeake. Measured gusts to 50 kt have been reported, with
   more widespread gusts of 40-45 kt noted, in addition to sporadic
   wind damage across the region. This should continue as storms track
   eastward across a strongly unstable airmass with very steep low
   level lapse rates and high PW values. Wet microbursts embedded
   within the larger complex of storms will continue to be the main
   concern with this activity as storms move out of WW 393 and into WW
   394, though a few more discrete/isolated cells across northern NJ
   earlier this afternoon also produced marginally severe hail.
