Snowfall rates of 1-2 in/hr will persist within the heavy snow band, with liquid-equivalent rates of 0.05-0.15 in/hr common in mixed precip. DISCUSSION...A long-lived/well-developed swath of winter mixed precipitation is ongoing within a strong low-level warm theta-e advection regime across the Northeast. A band of heavy snow with rates likely near 2 in/hr is ongoing from roughly the Glens Falls, NY to Augusta, ME corridor per latest surface observations and radar imagery. This heavy snow band should pivot northeast in tandem with the shift in 850-mb frontogenesis through early afternoon. This will also yield a pivot from the ongoing west/east-orientation of the transition zone to sleet and freezing rain. As a result, southern portions of VT/NH/ME will transition to mixed precip by midday. Meanwhile, the heavy snow arc will shift more into northern parts of VT/NH to central ME. ..Grams.. 03/23/2024 ...Please see www.spc.noaa.gov for graphic product...
