MD 0287 CONCERNING WINTER MIXED PRECIPITATION FOR PARTS OF NEW ENGLAND AND EAST-CENTRAL NY
Mesoscale Discussion 0287
NWS Storm Prediction Center Norman OK
0729 AM CDT Sat Mar 23 2024
Areas affected…Parts of New England and east-central NY
Concerning…Winter mixed precipitation
Valid 231229Z – 231630Z
SUMMARY…A mix of heavy snow, sleet, and freezing rain will
gradually shift east-northeast from east-central New York across
parts of New England into early afternoon. 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.
