   Areas affected...Tug Hill Plateau/vicinity

   Concerning...Heavy snow 

   Valid 312339Z - 010445Z

   SUMMARY...Heavy lake effect snow should continue this evening across
   portions of northwest New York in the lee of Lake Ontario. Snowfall
   rates of 1-3" per hour are expected.

   DISCUSSION...A band of heavy lake effect snow continues across
   portions of northwest New York in the lee of Lake Ontario. According
   to the KTYX radar, southern/central Jefferson, northern Oswego, and
   northern/central Lewis counties are currently under this band with a
   7.1 inch snowfall report recorded at 21:30 UTC near Watertown in a
   two-hour period. Surface winds should remain favorable for a large
   fetch across the lake with latest high-resolution guidance showing a
   southward shift during the next few hours. Building heights aloft
   and veering winds with height in the low-levels will begin to limit
   the depth of the convection from west to east across Lake Ontario
   later this evening. However, this will be a gradual process and a
   band of heavy snow is expected to continue through the evening
   before dissipating tonight.

   The forecast southward shift of the lake effect band would impact
   Oswego/Lewis counties and into northern Oneida county with snowfall
   rates of 1-3 inches per hour expected. Winds should remain gusty
   leading to hazardous travel conditions with blowing/drifting snow in
   addition to the heavy snowfall.
