   Areas affected...portions of eastern New York into southern New
   England

   Concerning...Freezing rain 

   Valid 060232Z - 060830Z

   SUMMARY...Light to moderate freezing rain has begun across portions
   of eastern New York into southern New England and is expected to
   continue over the next 4-6 hours, especially for high elevations.

   DISCUSSION...DCVA ahead of an approaching mid-level shortwave trough
   will overspread portions of the Northeast over the next 4-6 hours.
   Coupled with increasing 850 mb warm air advection, this is expected
   to support an expansion of light to moderate freezing rain rates
   already noted at some ASOS sites across portions of eastern New York
   into southern New England. While regional surface temperatures are
   hovering at or just above freezing in the low-to-mid 30s, modest
   surface temperature decreases are expected over the next couple of
   hours given weak surface cold air advection and evaporative cooling
   amidst surface wet bulb temperatures near freezing. The greatest
   potential for freezing rain rates to exceed 0.06"/3 hours is
   expected across areas of higher terrain, particularly across the
   eastern Catskill Mountains, Berkshires, Litchfield Hills, and
   Worcester Hills. Rates are generally expected to remain lighter
   within the intermediate Valleys owing to marginally warmer surface
   temperatures, but heavier rates may be supported should stronger
   surface CAA infiltrate these areas of lower terrain. Cooler
   low-to-mid level temperatures are expected to support snow as the
   primary precipitation type for areas farther north.
