By midday, the heaviest snow skirted into Michigan, Indiana and southern Illinois, dropping several inches of snow in just a few hours.
Precipitation started as rain across parts of the Ohio Valley; however, as Arctic air is pulled south on the backside of the storm, rain is forecast to gradually change over to snow into Monday evening.
Farther south, temperatures will be marginal, reducing the amount of time it will be cold enough for snow to fall from central Pennsylvania to southern Maine.
Widespread snowfall totals of 1 to 3 inches are likely across the Ohio Valley and into the Northeast, with 3 to 6 inches of snow expected from the Great Lakes into the interior New England.
“We expect a swath of higher snowfall totals from central New York to northern Maine, where accumulations could climb into the double digits,” said AccuWeather Meteorologist Courtney Travis.
Any icy spots on roadways on Tuesday can lead to dangerous travel conditions, especially for the morning commute.
On Tuesday, any wintry mix along the coast of Maine is expected to change over to snow, while snow will continue to fall elsewhere in northern New England.
With snow expected across these areas for the duration of the storm, higher snowfall totals are anticipated.
Icy conditions and accumulating snow will spread across the Northeast early this week as a potent snowstorm pushes through the region. The storm that brought snow to the Rockies and High Plains on Sunday will continue to sink south. This storm will bring some snow and Arctic cold to parts of the southern Plains.
After strengthening early on Monday, the storm shifted east and sent it snow from Missouri into the western Great Lakes. Midway through Monday morning, the snow had already impacted millions in the Chicago area. According to FlightAware.com, over 350 total flights were cancelled arriving to or departing from Chicago O’Hare International Airport. At Chicago Midway International, over 90 total flights have been cancelled.
