Icy conditions and accumulating snow will spread across the northeastern United States 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 into the beginning of the week. This storm will bring some snow and Arctic cold to parts of the southern Plains.
As the storm strengthens over the central and southern Plains on Monday, it will send snow from Missouri into the western Great Lakes. By the afternoon, snow is expected to spread into western New York.
From northwestern Pennsylvania to southern Missouri, precipitation will likely start as rain, but as Arctic air is pulled south on the backside of the storm, rain is forecast to gradually changeover to snow across these areas Monday afternoon and evening.
Icy conditions are expected to develop from northern Pennsylvania into southern New England Monday night and into Tuesday. Cold air at the surface will push under the warmer air in these areas and may allow rain to mix with ice and snow.
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.
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 is 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," stated AccuWeather Meteorologist Courtney Travis.
With snow expected across these areas for the duration of the storm, higher snowfall totals are anticipated.
Icy conditions and accumulating snow can lead to dangerous commute for motorists traveling on parts of Interstates 70, 76, 80, 81, 86, 87, 90 and 476.
"Mainly rain is predicted for the major I-95 cities from Washington, D.C., to Philadelphia and New York City; however, cold air may rush in and allow some flurries to develop at the end of the storm," added Travis.

In the wake of this storm, the next round of Arctic air will surge into the region Tuesday and into Wednesday.
Cold air rushing into the region over the warm water of the Great Lakes will trigger lake-effect snow showers in the beginning of the week.
"Northerly winds will generate snow south of Lake Michigan and Lake Superior as early as Monday afternoon," said Travis. "The wind direction should become a little more northwesterly by Tuesday morning, and lake-effect snow may be triggered downwind of Lake Huron, Lake Erie and perhaps Lake Ontario."
Snow can pile up to the south and east of the lakes, especially where persistent snow bands set up. Due to the duration of the lake-effect snow in parts of Michigan and northern Indiana, higher snow totals area expected there.
An AccuWeather Local StormMax™ of 30 inches is possible in this region where persistent lake-effect snow bands set up.
Elsewhere in the Northeast, bitterly cold air will spread across the region. A stiff breeze across the region will drop the AccuWeather RealFeel® Temperatures about 10 to 20 degrees lower than the actual temperature.
AccuWeather meteorologists are predicting that 147 million Americans will experience subfreezing AccuWeather RealFeel® Temperatures by Tuesday morning.
By Wednesday morning, temperatures look to fall into the teens across much of the region, nearing record-low temperatures across the area.
High pressure bringing the cold will shut off lake-effect snow by Wednesday morning, and will promote dry conditions across the Northeast through the middle of the week.
