Mesoscale Discussion 2257
NWS Storm Prediction Center Norman OK
0807 AM CST Wed Dec 10 2025

Areas affected...portions of central into eastern New York

Concerning...Heavy snow 

Valid 101407Z - 101800Z

SUMMARY...Moderate to heavy snow is expected to persist into the
late morning and perhaps early afternoon hours. A few localized
instances of 1 inch/hour snowfall rates may occur.

DISCUSSION...A primary band of moderate to heavy snow has become
established over much of New York as a surface low approaches from
the Great Lakes, resulting in increased low-level WAA over the
Hudson Valley. At the terminus of the WAA resides strong 925-850 mb
convergence, which may be providing enhanced lift within a
saturated, sub-freezing troposphere. As such, efficient dendritic
growth should result in widespread moderate to occasionally heavy
snow through the morning hours, perhaps extending into early
afternoon, before the aforementioned WAA axis shifts east, away from
the Hudson Valley. Localized instances of 1 inch/hour snowfall rates
are possible.

thunderstorm potential across the CONUS appears minimal.
