   Concerning...Severe Thunderstorm Watch 538...

   Valid 222320Z - 230015Z

   The severe weather threat for Severe Thunderstorm Watch 538
   continues.

   SUMMARY...Locally damaging winds are possible over the next hour as
   a cluster of storms tracks northeast toward, and just south of, the
   Washington, D.C. area.

   DISCUSSION...A bowing segment tracking northeast around 45-50 kt
   toward the D.C. Metro vicinity has produced multiple wind-damage
   reports over the last hour or so. Radar trends have generally
   decreased, but mostly recently some new invigoration of cells along
   the leading edge of this cluster have occurred. Regional radar still
   shows near-50 kt velocities at around 3 kft and KLKU recently
   reported a 39 kt gust. If this convection is maintained, or
   re-intensifies, a corridor of locally damaging winds is possible
   over the next hour as the cluster tracks toward the greater
   Washington D.C. Metro vicinity.
