   Areas affected...parts of New England and eastern NY

   Concerning...Heavy snow 

   Valid 090301Z - 090700Z

   SUMMARY...Multiple bands of heavy snow with rates of 1-2 inches per
   hour should persist into the early morning across eastern New York
   into parts of New England.

   DISCUSSION...Radar imagery and surface observations, along with
   recent reports, indicate multiple swaths of heavy snow are ongoing
   across parts of the Northeast. The most probable area for the
   highest rates should exist over southern New England, just to the
   east-northeast of the occluding transition zone between snow and
   sleet. OKX dual-pol radar has sampled enhanced KDP below the
   dendritic growth zone, indicative of heavy snow. 21Z SREF and 00Z
   HREF guidance support potential for 2 in/hr bursts across parts of
   CT/MA/RI, until enough warming near 700 mb occurs for sleet and/or
   mid-level drying advects into the dendritic growth layer during the
   early morning. 

   Farther north, a more west/east-oriented deformation zone from Lake
   Ontario to the Capital District should pivot east during the next
   several hours. Snowfall rates in this band should more steadily hold
   around 1 in/hr as it spreads across southern parts of VT/NH/ME.
