Areas affected...NJ...Central/Eastern MD...DE

Concerning...Severe Thunderstorm Watch 530...532...

Valid 210826Z - 211000Z

The severe weather threat for Severe Thunderstorm Watch 530, 532
continues.

SUMMARY...Isolated damaging gusts remain possible across NJ,
central/eastern MD, and DE for the next hour or two.

DISCUSSION...Long-duration convective line continues to push
eastward/southeastward across far southeastern PA and northeastern
MD at 25-30 kt. A few sites gusted around 30-35 kt as the line moved
through, and this gust strength will likely be maintained over the
next hour or so across northern/central portions of the line (i.e.
portion of the line entering NJ) where the shear is more orthogonal
to the line. Additional strengthening of this portion of the line is
unlikely given only modest buoyancy downstream and limited
deep-layer shear.=20

Additional development has occurred farther south into more of
central and eastern MD, and a few stronger gusts have been noted
here as well as cold pool amalgamate. Isolated damaging gusts are
possible for the next hour or two as the portion of the line
progresses southeastward into more of the Eastern Shore.
