Areas affected...portions of northern VA into western MD

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.
