SUMMARY...A new watch may be needed downstream of WW 192 and 193.
Locally damaging wind and hail threat could persist for several more
hours eastward toward the I-95 corridor and southern NY.
DISCUSSION...Scattered severe thunderstorms continue to track
northeast across central and eastern PA and eastern NY. Storms have
remained semi-discrete with a tenancy toward upscale growth into
bowing structures. Convection may persist beyond the 01z expiration
time of WW 192 and 193 across parts of far western PA into southern
NY and NJ where a very moist airmass (surface dew points in the
upper 60s to low 70s) beneath steep midlevel lapse rates. As a
result, a corridor of 1000-2000 J/kg MLCAPE resides from southeast
PA into southern NY. Effective shear around 30 kt should remain
adequate to support semi-organized structures into this evening and
a locally damaging wind and hail threat could spread eastward toward
the I-95 corridor/southern NY through around 04-05z. As such, a new
watch may be needed.
