A glancing blow from the polar vortex will direct cold air southward and could raise the chance of snow in the central and eastern United States toward the middle of January.
The pattern of cold air coming and going will be a theme through January.
According to AccuWeather Chief Meteorologist Elliot Abrams, “Arctic air will leave quickly, after giving the Great Lakes and Northeast a cold shock this week.”
Temperatures will rebound to above-average levels in much of the Midwest and Northeast during the latter part of this week and this coming weekend.
High temperatures will return to the 30s in Minneapolis, the 40s in Chicago, the 50s in Washington, D.C., and the 60s in Atlanta for multiple days. The warmup will be of short duration. (Read more from “Polar Vortex to Usher Widespread Cold, Snow Chances Into US During Mid-January” HERE)
