The snowfall for Sunday night appears to be on schedule, with no real surprises to speak of:
- Snow begins between 12am to 4am (closer to 12am near PA, closer to 4am near CT)
- Light snow falls steadiest between 2am and 6am
- Light snow mixes with rain in the southern HV (south of I-84) after sunrise
- Light snow (south HV mix) tapers off from west to east between 8am and 12pm
- Valley areas south of I-84: Coating to 1 inch
- Valley areas near and north of I-84: Coating to 2 inches
- Higher elevations/Catskills: 1 to 3 inches
- Valley areas south of I-84:
- main roads likely wet, secondary roads snow covered. Watch for slick spots
- Valley areas north of I-84:
- most roads likely snow covered and slick. Take it slow, delays expected
- Higher elevations/Catskills:
- snow covered and treacherous roads. Delays likely, use extra caution
- Valley areas south of I-84:
This snowfall projection map helps paint the picture of what we expect. While cold, it’s not bitter cold just yet… and in early December, that means snow may struggle to accumulate in southern areas. Temperatures are expected to be 32° to 36° across the valley areas south of I-84… so just how much accumulation we see, will depend on exactly how cool it gets in the southern part of the valley. But if you go up in elevation, even a little bit… where it’s a degree or two colder, the hill towns of Orange and Putnam Counties could see up to 2 inches.
The northern areas, and especially the higher elevations, should be plenty cold enough for snow to accumulate on all surfaces. Generally, up to around 2 inches are possible… with maybe 3 inches or so in the mountains. As we’ve mentioned the past couple days… there isn’t a lot of moisture with this system, so totals should remain low.
But this time of year, it’s not going to take much snow on the road to cause for some big headaches. We wouldn’t be surprised if there were numerous school delays as a result. After sunrise, temperatures should gradually climb above freezing in the Hudson Valley… making for improving road conditions by the end of the AM commute. In the mountains, temps should hold at or below freezing… making for a longer period of slick travel on Monday morning.
We’ll try to have additional commentary as things unfold tonight. This is a minor winter event… but the first few of the season always generate the biggest headaches, as many of us re-learn how to handle the winter weather. Be safe and take it slow in the AM.

Overall a pretty great Sunday across the region with abundant sunshine, calmer winds but continued chilly temps. The first signs of our incoming weather will be increasing clouds later this evening. Light snow looks to snow spread into our region later tonight between 11pm-2am and fall steadily into the morning. Cold surface temps will allow snow to accumulate and areas of slick travel will develop for the morning commute.
This is not a heavy snowfall, 1-3 inches will be the general rule with the lowest amounts in the valley locations and southern zones, highest amounts across the hill towns and higher elevations. Despite the minimal amounts delays are possible and hazardous travel will also impact parts of our region, be prepared for this possibility and allow some extra time for travel. Roadways will improve rapidly after sunrise as temps warm back above freezing and even some rain falls in the southern zones.
We have an extremely active period of weather ahead of us, there is an ever increasing threat of multiple winter storms over the next 7-10 days, please stay tuned as we begin to dig into each of them over the next day. Everyone have a great end to their week, we will be back later with another update on the overnight snow.
