Arctic Air In Upper Midwest To Move East As Week Wears On

MINNEAPOLIS (CBSNewYork/AP) -- The upper Midwest is in the deep freeze, with the arctic air expected to shift eastward as the week wears on.

Climate Prediction Center forecaster Stephen Baxter says the cold will affect parts of the northern and eastern U.S. late this week and into the weekend, with much-below-normal temperatures expected in the Great Lakes, Mid-Atlantic and Northeast regions.

In the Tri-State area, highs Thursday and Friday will hang in the 20s with overnight lows dropping into the single digits and teens with wind chills below zero at times in some spots.

Forecasters say wind chills this cold can cause frostbite to exposed skin in as little as 30 minutes.

Up to half a foot of snow also could fall from the Upper Mississippi Valley to the Northeast Friday and Saturday.
