   Areas affected...far northern New York and northwest Vermont

   Concerning...Freezing rain 

   Valid 120732Z - 121230Z

   SUMMARY...Freezing rain will continue across far northern New York
   and northwest Vermont into the early morning. Heavy freezing rain in
   excess of 0.1 inch/hour is possible.

   DISCUSSION...Freezing rain has developed in the last 1-2 hours
   across northern New York and northwest Vermont. Warm air advection
   ahead of an approaching upper-level shortwave trough has led to
   isentropic ascent with strong frontogenetical forcing also occurring
   along the US-Canadian border from New York through New England. A
   warm nose continues to persist owing in large part to the warm air
   advection. However, the surface cold front has slid slowly southward
   tonight with surface temperatures in the upper 20s/low 30s F
   currently and likely to fall into the mid/upper 20s F by sunrise. As
   such, freezing rain, which may be heavy at times, will likely
   continue until 11-13z across northern New York and northwest
   Vermont.
