Heavy snow is focusing on northern New England this Sunday, causing even more travel disruptions.
The snowstorm has already spanned more than 1,000 miles. Snow has reached every major city and rural area from St. Louis to Boston, including Chicago, Detroit, Indianapolis, Cleveland, Pittsburgh, Philadelphia and New York City. The area encompasses about 110 million people.
Thanks to recent Arctic air making roads and sidewalks much colder compared to previous storms, enough snow to shovel and plow has occurred in Illinois, Wisconsin and Missouri and is in store from parts of Illinois, Indiana, Michigan, Ohio, West Virginia, Virginia, Maryland and New Jersey to much of Pennsylvania, New York, Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire and Maine.
Not only will the storm make roads and sidewalks slippery, raising the risk for slip-and-fall incidents and auto accidents, but it is likely to cause many flight delays and cancellations. The visibility will be poor, runways will become snow covered and aircraft will need to be de-iced.
The storm could cause shipping delays and force Christmas shoppers to change their plans for the weekend.
The recent cold weather, this storm, and others will translate to plenty of snow on the ski slopes.
In the wake of the storm, areas made wet and slushy from melting during the day on Sunday will freeze on Sunday night, producing patches of black ice.
The risk of a rapid freeze is already threatening Boston this Sunday morning.
Across northern New England, the storm is lingering this Sunday with ongoing travel disruptions. The worst of the snowstorm is focusing on Maine. Frigid temperatures is causing the snowfall to be very powdery.
Conditions will gradually improve as Sunday progresses and the storm shifts to Atlantic Canada.
While snow showers occur over the central Appalachians and downwind of the Great Lakes over the Midwest, the storm will be over across the Ohio Valley and coastal mid-Atlantic, and travel conditions will improve.
Long stretches of the I-69, I-75, I-80 and I-90 corridors have been hit with heavy snow, falling at the rate of up to an inch per hour in the Midwest.
Even though the snow tapered off early on Saturday night from west to east in this area, many secondary roads and city streets will remain snow covered until snow removal crews have a chance to get to them on Sunday.
Mostly rain fell from Roanoke, Va., to Washington, D.C., and Baltimore, but some roads from northern Virginia to northern Maryland became slippery due to a period where sleet mixed in with the rain.
However, farther northeast along the I-95 corridor from northern Delaware to around New York City, the change to rain following snow and/or a wintry mix took longer, leading to several inches accumulation and more widespread slippery travel. Central Park received 5 inches of snow before it changed over to plain rain in the city.
Snow was seen at the Army-Navy Classic on Saturday afternoon at Lincoln Financial Field in Philadelphia. This wintry game occurred just less than a week after heavy snow fell during the Eagles-Lions game. Snow buried the field and had players sliding and shoveling snow with their feet during last Sunday's game.
Cold air and flurries are in store for the New Hampshire primary on Tuesday but should not significantly impact voter turnout.
Snow and slippery travel will arrive in the mid-Atlantic states prior to the middle of the week.
Waves of arctic air invading the eastern half of the United States this week will culminate with the coldest weather of the season so far for some areas by the Valentine's Day weekend.
Chilly air will visit New Orleans this year for the annual Mardi Gras celebrations and linger over the city until later in the week.
Warmer air will build from California to Washington into Tuesday raising temperatures to near-record levels and increasing the risk of wildfires in some areas.
