Areas affected...Middle Atlantic

Concerning...Severe Thunderstorm Watch 415...

Valid 142220Z - 142345Z

The severe weather threat for Severe Thunderstorm Watch 415
continues.

SUMMARY...Locally damaging winds and marginally severe hail are
expected with convection early this evening.

DISCUSSION...Weak mid-level short-wave trough is ejecting across the
Middle Atlantic early this evening. This feature appears to be
aiding a broad corridor of convection that extends from the lower
Hudson Valley, arcing southwest across central NJ where convection
has recently intensified, possibly due to coastal boundary
interactions. Surface temperatures are seasonally warm ahead of this
activity, even near the coast where readings remain in the 80s.
Modest buoyancy extends across the Delmarva into southern New
England and this will contribute to new updrafts forming along the
leading outflow as the aforementioned complex advances east this
evening. Locally damaging winds are the primary risk along with
marginally severe hail.
