   Areas affected...South-central Virginia into central/eastern
   Maryland and southeast Pennsylvania

   Concerning...Severe Thunderstorm Watch 442...

   Valid 191922Z - 192115Z

   The severe weather threat for Severe Thunderstorm Watch 442
   continues.

   SUMMARY...Strong to severe winds are the primary threat this
   afternoon, particularly with linear segments. The environment in the
   DC/Baltimore/Philadelphia remains favorable.

   DISCUSSION...Strong to isolated severe wind gusts have occurred with
   storms just east of the Blue Ridge this afternoon. Given the linear
   structures that have evolved in northern Virginia and central
   Maryland, areas ahead of this activity will have a greater risk for
   strong/damaging winds. Temperatures in Virginia and Maryland have
   risen into the low 90s F with upper 80s F into southeast
   Pennsylvania. Steep low-level lapse rates and 1500-2000 J/kg MLCAPE
   will support a continued threat for strong to severe wind gusts as
   storms move towards the DC/Baltimore/Philadelphia corridor.
