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.
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.
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.
