Areas affected...portions of the Northeast

Concerning...Severe potential...Watch likely=20

Valid 181725Z - 181930Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe potential to continue downstream of WW352.

DISCUSSION...A line of low topped convection continues across
portions of New York and Vermont, producing reports of wind damage
across portions of New York state. This will continue to shift north
and eastward into portions of New Hampshire in the next few hours.
Strong low to mid-level flow around 50-60 kts, as observed by VAD
profiles at CXX and ENX, continues across the region This will
continue to support potential for damaging winds and perhaps
tornadoes as this line continues downstream. A watch will likely be
needed soon.
