Heavy snow rates of 1-1.5 in/hr will be most probable in a band along the northern periphery of the mixed transition zone. DISCUSSION...An extensive swath of mixed winter precip is ongoing across southern to eastern NY into parts of southern VT/NH. This has been aided by strong low-level warm theta-e advection amid a 50-60 kt low-level jet per ENX/BGM VWP data. Low-level warming has again been faster up the Hudson Valley than indicated by evening model guidance with prior 1"/hr snowfall rates at ALB transitioning to mixed freezing rain/sleet during the past hour. Based on recent radar trends, this mixed phase should be the dominant precip type as it gradually expands east-northeast into parts of MA and southern VT/NH in the next few hours. Precipitation rates from 0.04-0.12 in/hr should be expected based on upstream measurements/guidance. Heavier snowfall rates should still occur just to the north-northeast of the transition zone, with rates of 1-1.5 in/hr becoming increasingly probable across parts of northern VT/NH into a part of southwest ME through sunrise. ..Grams.. 03/23/2024 ...Please see www.spc.noaa.gov for graphic product...
