Weather For Everyone: Snow for New York State, Northern New England

Feb 23, 2012; 1:04 PM ET

The second snowstorm in two days will take aim on part of upstate New York, northern New England and neighboring Canada late tonight into Friday.

Several inches of snow will fall from Toronto, Ontario, to Burlington, Vt. and Houlton, Maine. Local accumulations of a half a foot or more are possible.

Neighboring Canada will pick up as much as 25 centimeters of snow from southern Ontario to the St. Lawrence Valley and into New Brunswick.

This new snow, combined with recent snowfall, will make for a long-awaited weekend boon for northern skiers and snowmobilers, as just enough cold air will come in and stay in to allow the snow to stick around for a couple of days.

The storm already produced snow in the Dakotas today and will bring a locally heavy accumulation from Chicago to Detroit tonight.

Road conditions will vary during the storm from wet to slushy to snow-covered. The conditions will depend largely on the intensity of the snow and whether or not the snow gets a head start during the nighttime hours in a particular area.

Generally, it has to snow very hard to stick to roads during the middle of the day with near or slightly above-freezing temperatures forecast for most areas. In the mountains, where it is typically a bit colder, more of the snow will stick to the roads.

Just south of the band of heavy snow, a zone of wintry mix is in store with little or no accumulation.

Farther south, a cold front swinging through Friday will mark the end of the recent warmth. Many areas will have several hours of gusty winds and a couple of showers. A few locations can be hit with a thunderstorm and brief powerful wind gusts.

The same storm is poised to bringsevere weather to parts of the Ohio and Tennessee valleys this evening.

In the wake of the storm, the air will be cold enough to produce lake-effect snow in downwind areas.
