   Areas affected...portions of the Northeast

   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.
