0931 PM CDT Fri Sep 08 2023
Areas affected…portions of eastern Maryland…northern
Delaware…extreme southeast Pennsylvania…southwest New Jersey
Concerning…Severe Thunderstorm Watch 674…
Valid 090231Z – 090330Z
The severe weather threat for Severe Thunderstorm Watch 674
continues.
SUMMARY…An instance or two of damaging gusts or marginally severe
hail may accompany the stronger storms for the next hour or so.
Thunderstorms should continue through early tonight, but with a
diminishing severe threat.
DISCUSSION…Mature multicellular clusters persist along a theta-E
axis near the Chesapeake Bay, where 75-80 F surface temperatures
remain in place. Though the boundary layer is decoupling, the
aforementioned warmer low-level airmass and associated buoyancy will
support brief bursts in convective intensity, and a damaging
gust/instance of marginally severe hail cannot be ruled out.
However, further boundary-layer stabilization should continue to
temper the severe threat into tonight.
