Concerning...Severe Thunderstorm Watch 205...206...
Valid 262041Z - 262145Z
The severe weather threat for Severe Thunderstorm Watch 205, 206
continues.
SUMMARY...Strong to severe thunderstorms will continue to produce
sporadic wind damage the next several hours as they moved eastward
across parts of the Mid-Atlantic and southern New England.
DISCUSSION...Clusters of strong to severe thunderstorms continue to
quickly progress eastward late this afternoon. Mainly weak
instability prevails across the region, with some pockets of MLCAPE
as high as 1500 J/kg closer to the Delmarva vicinity. While this
weaker instability and limited deep layer shear is subduing a larger
severe threat, very steep low level lapse rates are aiding in
periodic strong downdrafts. Sporadic damaging gusts have been
reported through the afternoon and this trend should continue with
the more intense clusters over the next few hours across eastern
portions of Severe Thunderstorm Watch 205 and into Severe
Thunderstorm Watch 206.
