A new winter storm, named Winter Storm Chan by The Weather Channel, will bring more snow to the Midwest after Winter Storm Bellamy impacted holiday travel. It will then head for the East, with a mix or snow and ice Tuesday and Tuesday night.
Happening Now
As the radar below shows, light snow is falling in parts of the Plains. The southern end of that wintry precipitation may be in the form of light sleet or freezing rain from parts of Oklahoma and Arkansas.
Winter Alerts
The National Weather Service has issued winter weather advisories from the Plains to the Midwest, Appalachians and parts of the Northeast. This usually means lighter wintry precipitation may lead to slippery travel.
Winter storm watches, however, have been posted in parts of the Northeast, from northeast Pennsylvania to Maine. This means heavier snow may fall in these areas. These watches do not include the immediate Interstate 95 corridor from downtown Boston southward.
Snow Timing, Amounts
In general, the Midwest will see its snow from this winter storm either Monday or Monday night.
The Northeast will see its snow Tuesday, with some lingering snow in parts of northern New England Tuesday night.
Midwest snow amounts will be light to moderate in most areas, generally on the order of 1 to 3 inches, though a few areas may see a bit more. This could lead to slippery travel later Monday, possibly lingering into Tuesday morning's commute.
In the Northeast, heaviest snow amounts of 6 inches or more are possible Tuesday just up the Hudson Valley from New York City into New England. Some localized amounts up to a foot are possible from parts of Massachusetts west of downtown Boston to southern New Hampshire and southern Maine.
This could lead to challenging travel in these areas Tuesday and Tuesday night, with snow-covered roads still lingering into the Wednesday morning commute.

Good news for the kiddos…the snow will stick around for a while as highs won't make it above freezing for the entire week. The upper level pattern will feature reinforcing shots of cold air every few days, leading to a stretch of cold and unsettled weather for many across the Midwest and Great Lakes.

Icing Potential
This won't all be snow.
There will be some areas of sleet and freezing rain from parts of Arkansas and the Mississippi Valley into the East through early Tuesday.
The best chance of accumulating ice will be in the southern Appalachians and adjacent Piedmont from western North Carolina to West Virginia and western parts of Virginia early Tuesday.
In some parts of the Shenandoah Valley southward into northwest North Carolina, there could be enough accumulation to make most roads slippery for a time, and could lead to a few power outages, as well.
First Measurable Snow For I-95 Cities?
Boston, New York City, Philadelphia and Washington, D.C. have already seen their first flakes of the season, but none of these cities have reported any measurable snow (0.1 inch or greater) yet this season.
We expect rain to be the most dominant type of precipitation in D.C., Philly and New York City, though we can't completely rule out a few flakes of wet snow either as the precipitation first begins or ends.
The best chance of measurable snow of these cities will be in Boston, where precipitation could change over to wet snow sometime Tuesday night.
