December is picking up right where November left off with cold air set to dominate the midwestern and northeastern United States this week, paving the way for more snow.

People from Minneapolis to Chicago, Detroit, Cleveland, Pittsburgh, Washington, D.C., and New York City got an early taste of winter with temperatures averaging 3-6 degrees Fahrenheit below normal during November.

With the exception of Minneapolis, above-normal snowfall was also recorded in each of these cities last month.

In the wake of the weekend storm, progressively colder air has begun and will continue to settle into the Northeast..

Temperatures plummeted on Monday throughout the eastern Great Lakes and northern New England, and they are expected to fall even further on Tuesday. High temperatures are forecast to be in the 20s F across upstate New York and New England and the 30s over the rest of the interior.

Tuesday’s will end up being 20 to 30 degrees lower than Sunday’s peak temperatures across the interior Northeast.

“Some snow showers are expected from the Great Lakes into the Northeast with this cold front from Thursday to Friday,” AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.

Snow could come close to St. Louis and may coat Chicago, Indianapolis and Detroit on Thursday, before reaching Pittsburgh and Syracuse, New York, late in the day or at night.

Locally heavier snow squalls are possible along this corridor.

Frigid air will settle in behind the front, with highs likely being held in the teens in Minneapolis and 20s in Chicago to end the week.

While the air will not be quite as cold when it reaches the Northeast, highs several degrees below normal will remain common at late week.

AccuWeather meteorologists are monitoring a storm that may tap into this cold air, spreading a swath of snow and a wintry mix from the central and southern Plains to part of the Eastern Seaboard late this week and into the weekend.
