Areas affected...Parts of eastern PA...northern/central
NJ...southeastern NY...and far western CT

Concerning...Severe Thunderstorm Watch 540...

Valid 072004Z - 072200Z

The severe weather threat for Severe Thunderstorm Watch 540
continues.

SUMMARY...The risk of scattered damaging wind gusts will continue
spreading east-northeastward across parts of Severe Thunderstorm
Watch 540.

DISCUSSION...A loosely organized band of thunderstorms is advancing east-northeastward across eastern PA and southeastern NY this
afternoon, where there have been several reports of wind damage.
This activity will continue spreading east-northeastward into an
increasingly warm/unstable PBL (lower 90s temperatures amid
lower/middle 70s dewpoints). Steepened low-level lapse rates and the well-established/strengthening cold pools will promote an increasing
risk of scattered damaging wind gusts over the next few hours. To
the north of Severe Thunderstorm Watch 540 in southeastern NY, a
narrow spatial overlap of sufficient/modest destabilization and
midlevel height falls will support a localized risk for damaging
thunderstorm wind gusts through the afternoon. A downstream watch is
not currently expected.
