Significant/Hazardous Weather
Very cold conditions will persist through at least Wednesday. Moderate winds will result in low wind chill values. Dress accordingly, and adjust your time outside.
Recreational Forecast
Mountain Forecast:
The summits today will see periods of clouds, most numerous north, along with occasional snow showers, more frequent through the Adirondacks, where light accumulations are possible. Southwest winds not as strong, but still moderate today, and temperatures remaining near zero, creating wind chills of 25 to 50 below zero. Wednesday brings more sunshine, light to moderate west and northwest winds, and little change in the deep winter cold, so another day of very low wind chill values. Thursday’s outlook calls for periods of clouds, a few passing snow showers, as temperatures begin to ease up, thanks to moderate southwest winds.
Wind At Lower Elevations:
Winds today becoming southwest 10 to 15 mph. Tonight, southwest winds near 10 mph this evening, diminishing to light. On Wednesday, winds light, mainly west less than 10 mph. The outlook for Thursday calls for south winds near 10 mph, gusting to 20 mph in the Champlain Valley.

Detailed Discussion
Thermometers have stumbled their way down to near or below zero this morning, plunging to the teens and a few 20s below in the Northeast Kingdom, the Eastern Townships, and then south through much of NH, where it remained clear the longest, and the fresh snow cover in NH helped to radiate yesterday’s meager warmth out through the atmosphere. Temperatures were significantly modified through NY and into the Champlain Valley, thanks to clouds coming off Lake Ontario, in part due to the westerly winds focusing lake effect snows east of the Lake, then snow showers extending into the Adirondacks. Lake Champlain also moderated temperatures through the Champlain Basin. In addition, a weak weather system over the Great Lakes, sitting between the arctic air here, and a second piece over the southern US, will also add a little moisture to the atmosphere, resulting in increasing periods of clouds, as well as a few snow showers through northern areas. Overnight, this minor system dissipates, allowing the skies to clear, which sends thermometers tumbling to near or below zero once again. With fewer clouds, areas in New York are likely to be several degrees colder. Tomorrow, high pressure re-establishes itself, delivering a bright blue sky, though another cold day. Fortunately, the winds will be light, and that should warm some of the valleys just a bit more. Before the temperatures can plunge tomorrow night, periods of clouds will increase from west to east thanks to another minor weather system arriving from the west. This represents the leading edge of more seasonable temperatures, and after some clouds, maybe even a few stray flurries north Thursday, general fair weather Friday into Saturday, with nights ranging from 5 below to 10 above, and daytimes in the upper teens and 20s. The cold this morning seems to have sparked more conversation than you might expect, at least considering the framework. This is January. Below zero nights are to be expected, which would seem to place such mornings in the “typical” category. Admittedly, recent mild winters have shifted perceptions, and most of us might not have reliable weather memories. To be clear, I am not talking about ancient history. One decade ago, February of 2015, more than a dozen nights dropped into the minus column, a few in the 20s and 30s below, part of the coldest three months on modern record, from January through March. I’m not sure if that makes this morning more comfortable, because, I’ll admit, below zero is below zero, and we’re not done with it yet.
