   Areas affected...portions of northern NY into VT and NH

   Concerning...Winter mixed precipitation 

   Valid 290554Z - 291200Z

   SUMMARY...Snow and freezing rain will increase over the next few
   hours hours across parts of northern New York into central/southern
   Vermont and New Hampshire. Mixed wintry precipitation is expected to
   persist into the early morning hours.

   DISCUSSION...Light to moderate snow is occurring over far northern
   NY into northern VT/NH tonight. Precipitation is expected to shift
   south and east over the next few hours within a band of strong
   850-700 mb frontogenesis, and as a surface front sags southward,
   allowing a shallow layer of sub-freezing near-surface temperatures
   to filter across the MCD area. Warm, moist advection atop the
   surface front within this zone of stronger ascent will support
   continued development of snow and freezing rain into the morning
   hours. Freezing rain rates may approach 0.02 inches per hour, though
   snowfall rates are generally expected to remain less than an inch
   per hour.
