Timing:
– 4pm to 7pm : Snow develops (mixed with rain in valley)
– 7pm to 6am : Snow/mix/rain falls light to moderate at times
– 6am to 3pm : Rain/Mix changes back to wet snow before ending
Impacts:
– Wide range of effects depending on location & elevation
– Mainly wet roads expected in valley, above 1500ft icy roads possible
– Expect some surprises, rain/snow line splitting our area in half
Snow Accumulation:
– Catskills & Taconics : 2″ to 6″ (locally up to 8″ above 1500ft)
– Mid & Upper Hudson Valley (north of I-84): Coating to 3″
– Lower Hudson Valley (south of I-84): Coating to 1/2″
A difficult forecast as the Hudson Valley is in the crosshairs of the rain/snow line. Precipitation will move into the Hudson Valley as sunset approaches on Sunday. Surface temperatures will be above freezing in the valley, and near freezing in the Catskills. Snow is likely to develop, mixed with rain in the valley areas. The question to monitor Sunday evening is, there will be a ‘warm layer’ of air about 5000 feet up, associated with the coastal low pressure system. Just how far north the warm layer of air pushes, will determine if we see the higher end, or lower end of snowfall ranges.
Temps are expected to remain at or just above freezing through the event, so snow accumulation is likely confined to unpaved surfaces. The Monday AM commute is likely to be impacted, but it will depend greatly on where the rain/snow line was overnight, and what conditions are in your area. Even with temps above 32°, some slick spots are possible.
The details with this system continue to remain in doubt… so we will have updates on Sunday to try and keep you a step ahead.
