MD 0079 CONCERNING HEAVY SNOW FOR PARTS OF NEW ENGLAND AND EASTERN NY


Mesoscale Discussion 0079
NWS Storm Prediction Center Norman OK
0901 PM CST Sat Feb 08 2025

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.
