The severe weather threat for Severe Thunderstorm Watch 58
SUMMARY...A widespread damaging wind threat will continue across
Severe Thunderstorm Watch 58 with a line of thunderstorms.
DISCUSSION...A line of shallow convection with occasional embedded
lightning strikes has produced numerous measured severe wind gusts
in addition to trees down/damage reports across VA, MD, and DC over
the past several hours. This line is moving quickly eastward around
60 mph, and it will continue to pose a widespread damaging wind risk
across the Delmarva Peninsula and NJ until it moves offshore. Across
southeastern VA, the line has not regenerated, possibly due to
slightly stronger capping in the 850-700 mb layer compared to
locations farther north. Regardless, a conditional damaging wind
threat exists across southeastern VA. Across central/northern NJ
into far southern NY, the atmosphere remains only weakly unstable,
and the prospect for an appreciable wind threat north of the current
Severe Thunderstorm Watch remains unclear.
