   Areas affected...Virginia into the Delmarva region

   Concerning...Severe Thunderstorm Watch 503...

   Valid 252001Z - 252200Z

   The severe weather threat for Severe Thunderstorm Watch 503

   SUMMARY...The potential for damaging winds and sporadic hail
   continues across WW 503. A corridor of higher wind damaging
   potential may emerge across eastern Virginia and Maryland.

   DISCUSSION...Over the past hour, thunderstorms emerging from the
   central/southern Appalachians have intensified and begun to produce
   isolated damaging winds with an occasional report of severe
   hail/measured severe wind gusts. Most convection has consolidated
   into a broken line from the Washington D.C. region southward into
   southern VA, but a few isolated cells are beginning to develop ahead
   of the line from eastern VA into eastern PA/NJ. Although regional
   VWPs and ACARs soundings show minimal change in the kinematic
   environment over the past couple of hours, the thermodynamic
   environment continues to improve with MLCAPE increasing to 2000-2500
   J/kg across the region with steepening low-level lapse rates. This
   will maintain the potential for damaging/severe winds through the
   remainder of the afternoon and into the evening hours. 

   A localized corridor of higher damaging wind potential may emerge
   across northern VA into eastern VA/MD within the next 1-2 hours.
   Latest KLWX imagery shows a somewhat more organized portion of the
   line with a consolidated outflow. Low to mid-level winds are
   oriented roughly orthogonal to this portion of the line, which
   should aid in maintaining storm organization/intensity for the
   near-term. Additionally, a measured severe wind gust of 67 mph was
   noted with this line, further suggesting that areas ahead of this
   line could see a locally higher threat for wind damage.
