There is a high degree of difficulty with this forecast, because of these details. But the low pressure will not move away until early morning Wednesday, so the position of the heavy snow band as it stalls out, could mean the difference between 6 to 8 inches… and 12 to 18 inches of snow. The snow bands will begin to pivot as the low pressure slowly drifts eastward. The counter clockwise rotation will spin snow bands northwestward, into the Hudson Valley. The coastal low pressure will spin off shore, and how close to the coast it is will determine where the position of the heaviest snow bands are. The big question is what happens after that. The initial wave that pushes northward between late morning and early afternoon is likely to see rates of snow over 1″ per hour. It’s at that point, that the snow band is likely to intensify to our south… and begin pushing northward, into the Hudson Valley. The low pressure over the Ohio Valley will weaken, and transfer its energy to the coastal low pressure. But there is considerable uncertainty due to the dry air, so the start times may be updated on Sunday. If this scenario is correct, 1 to 3 inches of snow would be possible in the mid and lower Hudson Valley by Monday morning. Above is the futurecast radar from 6pm Sunday to 6am Monday, and the snow moves into the low half of the Hudson Valley before midnight, but struggles to move north from there. All in all, it’s likely to bring a long duration snow event to the region.įuturecast Radar : 1pm Sunday – 6am Mondayĭry air pushing south from New England will delay the northern progress of the snow band.

The cold air, storm track, and intensity will all combine for a challenging forecast for the Hudson Valley. That coastal storm will intensify and move northeast, spreading snow from the Mid Atlantic states, through the Hudson Valley, and into New England. Low pressure from the Midwest will weaken as it moves into the Ohio Valley, and a secondary low pressure will develop off the coast of Virginia. – Lower Hudson Valley (Zone 8&9) : 8 to 16 inches – Lower Catskills, Mid Hudson Valley (Zone S3, S4, 5, 6, 7) : 6 to 12 inches – Western Catskills, Upper Hudson Valley (Zone 1, N3, N4) : 5 to 10 inches – Eastern Catskills (Zone 2) : 8 to 16 inches – Extremely difficult/dangerous travel Monday PM – Tuesday AM – White out / Blizzard conditions possible at times – NE winds 10 to 20mph, gusts over 30mph, blowing & drifting snow – Heaviest snow likely late Monday morning through Monday evening – Monday AM commute could be impacted, especially I-84 on south – Start time delayed by dry air in northern half of Hudson Valley

– Long Duration event expected, snow could last for 24 to 36 hours – 12pm to 6pm Tue : Snow tapers off from west to east – 6pm Mon to 12pm Tue : Light to moderate snow possible – 10am to 6pm Mon : Moderate to Heavy snow possible – 6am to 10am Mon : Moderate snow develops from south to north – 9pm Sun – 6am Mon : Light snow develops south to north (especially I-84 on south) Winter Storm Watches are in effect for the entire Hudson Valley, as we track a complex storm system that is likely to bring a long duration snow event to our region.
