A complex winter storm will start today in the Midwest with heavy snow from the Upper Mississippi Valley to the Ohio Valley, including the Chicago metro area and eventually into the Northeast, according to the National Weather Service. Chicago should see 5 to 9 inches of snow, its second snowstorm within one week.

On Sunday, the snow and wintry mix will spread into the Mid-Atlantic region. Washington D.C. could see 4 to 6 inches of snow in what could become the city’s biggest snowstorm in two years.

A potential Nor’easter will then intensify and significantly impact portions of the Mid-Atlantic, Northeast and New England on Monday and Tuesday.

By Sunday evening, the snow will move into Philadelphia and by Monday morning, snow will fall heavily along I-95 from Philadelphia to New York City to Boston.

Snowfall rates could reach 1 to 2 inches per hour on Monday and Monday night, the National Weather Service in New York said.

Snow totals are expected to reach 5 to 11 inches in Philadelphia and 6 to 10 inches in New York and Boston.

The rain over the Southeast will shift offshore by Monday morning.

Overnight, snow will move into southern portions of the Mid-Atlantic. There will be areas of rain/freezing rain over parts of western Virginia and North Carolina on Sunday.

While the snow will wane over the Upper Midwest overnight Sunday, it will continue over the Ohio Valley, parts of the Great Lakes, and into the Mid-Atlantic through Monday morning.

Meanwhile in the West, multiple fronts will move into the Pacific Northwest/Northern California today.  The systems will produce rain and higher elevation snow over the Pacific Northwest and Northern California, continuing through Monday morning.
