- Snowfall rates up to 1 inch per hour possible.
- Reduced visibilities – during heavy snow, visibilities could be reduced to less than 1/4 mile.
- Snow could mix with sleet & freezing rain before ending in Zones 8 & 9, icy travel could be a concern.

A frontal boundary will approach the Hudson Valley on Sunday. Warm air aloft, will ride over the cold dome of air we have at the surface… and that will generate upward motion, and precipitation. That precipitation will fall as snow across the Hudson Valley, and due to the strong low level jet stream, parts of the area could see a moderate snowfall out of this event.
Light snow advances into the HV early on Sunday, and while the snow should be quite light thru lunch… slippery travel may be a problem before the noon hour. But by the afternoon, we’re rapidly seeing the snow intensify across the Hudson Valley. We’ll see snow fall moderate (to at times heavy) thru much of the afternoon…
We’ll see the heaviest snow from 2pm to 8pm on average… and during that time snow could briefly fall as heavy as 1″ per hour, which could dramatically reduce visibility. The snow should continue thru the evening, before tapering off later (near midnight)…
Snow should end around midnight… but the slick conditions could last into the morning hours on Monday. So we’ll have to monitor the conditions for the Monday AM commute, as there could be some headaches.
The computer models are a bit unsure how the snowfall will stack up when all is said and done. Here are the GFS and NAM model’s respectively…
The GFS says it’s a 2 to 4 inch storm on average, the NAM says many places could break 6 inches. The HVW snowfall forecast is for a general 3 to 6 inches with some localized amounts up to 8″ possible. The best chance for the highest totals appears to be near I-84, but only time will tell, and we’ll have to see how the storm unfolds. Updates will follow as needed on this storm… another snowy Sunday shaping up for the Hudson Valley.
