The arctic blast headed to the Great Lakes will be accompanied by accumulating snow and a threat for icy spots.
A band of rain and snow pressing through the Great Lakes--in a northwest-to-southeast fashion--Sunday night through Monday night will signify the arctic air's arrival.
The arctic blast will be strong enough for the rain to change to a general coating to an inch of snow in many communities.
Cities in line to be lightly whitened by the snow include Chicago, Ill., Grand Rapids, Mich., Cleveland, Ohio, Erie, Pa., and Syracuse and Binghamton, N.Y.
Monday night, a coating to an inch of snow is also expected in Indianapolis, Ind., Columbus, Ohio, Pittsburgh, Pa., and Morgantown, W. Va., as the snow sinks southward across the central Appalachians and to the upper Ohio River.
A few places could even see totals approach two inches, mainly south of Lake Erie and in the higher terrain of the central Appalachians.
While a major snowstorm is not expected, the snow still threatens to cause problems for travelers.
Slick spots could develop on some untreated roads and sidewalks as temperatures plummet below freezing. That is especially true on bridges and overpasses.
Motorists who see snow mainly accumulating on grassy surfaces should not let their guard down in regards to the above danger. The wet road surfaces could still turn icy.
Airline passengers could experience some flight delays.
In the wake of the initial band of rain and snow, places downwind of the Great Lakes will see more snow through Tuesday as the arctic invasion activates the lake-effect snow machine.
In the heaviest lake-effect snow bands, the potential exists for 6 to 12 inches to accumulate across the Upper Peninsula of Michigan and 3 to 6 inches elsewhere downwind of the Great Lakes.
Outside of the Great Lakes and central Appalachians, wet snowflakes are only expected to make an appearance and not accumulate along the I-95 corridor of the Northeast Monday night through Tuesday.
Snowflakes could even been seen in Charlotte, N.C., and Atlanta, Ga., Tuesday night as an inch or two of snow whitens the higher terrain of the southern Appalachians.
