Concerning...Severe potential...Watch likely 



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.
