Coldest Air of the Season Arriving

Tuesday Highs

Tuesday Morning

With the jet stream blasting straight south out of northern Canada, cold air will continue to flood the eastern two-thirds of the country into Tuesday.

Subzero cold is possible Tuesday morning in both Chicago and Milwaukee.  Typically, this occurs with the assistance of snow cover, both reflecting the sun’s energy during the day, and refrigerating the air mass.  Dating to 1871, only 2% of all days with subzero lows in Milwaukee occurred without snow on the ground.  Tuesday morning may be one of those rare occurrences.

Farther north, temperatures will easily plummet well below zero, with places from Fargo to International Falls and Duluth likely to see minus 20s and even a few towns in the minus 30s!

In fact, the cold air will probably reach its greatest areal extent Tuesday. Cities as far south as Nashville and Richmond may not make it above freezing all day.

Major Great Lakes cities such as Chicago and Detroit will struggle just to hit 10 degrees Tuesday, and lake-effect snows are likely to continue in favored lake-effect snow belts southeast of all five major lakes.

All cities along the I-95 corridor from Boston to D.C. will see highs in the 20s. Single digits and teens for highs are likely from northern New England to western New York and western Pennsylvania.

Not only will it be much colder in New England, but commuters will have to deal with the effects of Winter Storm Jove, especially in the morning.
