Big snow Sunday into Monday
Update #689b: A major storm will bring a lot of snow to the Hudson Valley.
This one’s for all the snow lovers out there 💙
The weekend storm has continued to trend north, putting the Hudson Valley in the thick of the forecast heaviest snow.
Here’s what to expect:
Timing
Snow will start before dawn on Sunday and continue into Monday. The worst of the storm will occur on Sunday and Sunday night.
Amounts
Because of frigid temperatures in the single digits and teens, the snow will be super fluffy and accumulate efficiently. It will have no trouble piling up.
My early forecast is for 10 to 20 inches of snow across the region. That’s subject to change, but I think this has the makings of a big storm.
One thing I’m watching is the potential for snow to change to a wintry mix closer to New York City, including Rockland and Westchester Counties, which could suppress accumulation there somewhat. If that mix line creeps farther north, it could affect forecast snow amounts.
Impacts
On Sunday and Sunday night, deep snow cover may make roads impassable and lead to closures. Blowing and drifting snow may also create disorienting conditions.
At this point, school closings look likely on Monday as snow gradually ends and the cleanup begins.
For people flying into and out of hubs in the Northeast on Sunday and Monday, expect numerous cancellations. Consider changing your plans.

Buckle up!

The meteorological dynamics of major winter storms reveal fascinating parallels with glacial formation processes. What strikes me most about heavy snowfall events is how they demonstrate the same accumulation principles that drive glacier formation - consistent deposition under specific temperature and moisture conditions. The Hudson Valley's topography creates unique snow enhancement patterns similar to orographic effects observed in glacier-forming regions. From a climatological perspective, understanding these intense precipitation events provides insights into how historical glaciers advanced and retreated across this landscape during ice ages. The "super fluffy" snow characteristic mentioned represents low-density accumulation that, over geological timescales, would compact into glacial ice through similar metamorphic processes. Modern storm prediction capabilities allow us to observe in real-time the atmospheric conditions that, when sustained over millennia, sculpted the valleys and mountains we see today.
