Snow expected from Midwest to Northeast, then bitter cold
CHICAGO, IL - A winter weather system expected to dump more than a foot of snow in some places has begun its trek east, with a separate blast of arctic air on its heels.
The National Weather Service says the fast-moving clipper system that's already brought snow to parts of the upper Plains and Midwest is expected to leave as much as 5 to 7 inches in the Chicago area early Tuesday. Heavier snow bands and lake-effect snow could increase precipitation totals as the system heads east.
It's expected to weaken as it nears the East Coast, but mid-Atlantic states could get a couple of inches Tuesday.
After the snow, a high-pressure system over Canada will move southeast, bringing even colder temperatures Wednesday to the eastern two-thirds of the U.S.
