   The severe weather threat for Severe Thunderstorm Watch 242
   continues.

   SUMMARY...Organized convective line continues to move quickly
   southeastward across southeast PA. Damaging wind gusts will remain
   possible as the line moves through the remainder of southeast PA and
   into central/southern NJ.

   DISCUSSION...Organized convective line continues to move quickly
   southeastward across southeast PA. Recent storm motion was estimated
   at 60 kt. This line is occurring within an environment characterized
   by strong mid-level flow. Current mesoanalysis estimates over 50-60
   kt 500-mb flow and the CCX VAD recently sampled over 50 kt at 2 km.
   These strong westerly winds are contributing both to fast storm
   motion as well as the potential for strong gusts within the line.

   Downstream air mass across southeast PA and central/southern NJ is
   warm, with temperatures in the low to mid 80s, and modestly moist
   with dewpoints in low 60s. Somewhat warmer low to mid-level
   temperatures are tempering the instability as well as contributing
   to convective inhibition. As such, even with the strong flow aloft,
   wind gusts might not reach the strength otherwise supported by the
   kinematics. Even so, damaging wind gusts will be common along the
   line as it continues into southeast PA and central/southern NJ.

   There is at least some potential for the line to backbuild along its
   southwestern flank into north-central MD, then continuing eastward
   into northern DE. This would bring the potential for damaging wind
   gusts into those areas.
