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. ..Grams.. 02/09/2025 ...Please see www.spc.noaa.gov for graphic product...
