Areas affected...Portions of southeastern NY...western MA...and
southern VT

Concerning...Tornado Watch 617...

Valid 091827Z - 092000Z

The severe weather threat for Tornado Watch 617 continues.

SUMMARY...Within Tornado Watch 617, a potentially favorable corridor
for a couple tornadoes is evident from southeastern NY into western
MA and southern VT this afternoon.

DISCUSSION...Latest visible satellite imagery indicates filtered
diurnal heating (temperatures climbing into the upper 70s/lower 80s)
within small cloud breaks in the vicinity of an east/west-oriented
warm front moving slowly northward across southeastern NY to near MA
and VT. Given the high-PW/tropical airmass in place, this heating
may yield sufficient (albeit weak) MLCAPE for a couple low-topped,
surface-based showers/storms this afternoon. Any convection that can
root in the boundary layer may evolve into low-topped supercells,
aided by strong deep-layer flow/shear associated with Post-Tropical
Cyclone Debby. 

Additionally, the aforementioned corridor will be located beneath
the core of a northward-advancing low-level jet during peak heating
-- on the eastern periphery of the most substantial surface-pressure
falls. Here, large, clockwise-curved/sickle-shaped hodographs
(around 400 m2/s2 0-500m SRH per KENX VWP), will conditionally
support a couple tornadoes with the more robust surface-based
convection.
