   Areas affected...Western New York...and portions of New England

   Concerning...Heavy snow 

   Valid 100025Z - 100430Z

   SUMMARY...Heavy snowfall with rates 1-2+"/hr through the evening.

   DISCUSSION...A surface low continues to lift northeastward across
   southern Michigan. Deep moisture and strong ascent have overspread
   portions of the northeast into New England where heavy snow has been
   reported. HREF ensemble guidance indicates high probability that
   heavy snow will continue across this region through the evening,
   with potential for 1-2+"/hr rates at times. Strong warm air
   advection from the southeast is ongoing at this hour, with a
   transition zone where warmer temperatures are located to the
   southeast of the heavier snowfall. Mixed precipitation will likely
   continue in this region with lower elevations changing back over to
   rain through the evening. Heavy snow will spread north and east
   through New England the evening and overnight.
