Blast of arctic air invades Upper Midwest and Northeast next week, bringing early winter preview for millions

The colder temperatures will reach parts of the Southeast with projected low temperatures in the 30s on Monday for places like Atlanta and as far south as Jackson, Mississippi.

An early winter preview is forecast for the Upper Midwest, the Ohio Valley and the Northeast next week, as a strong dip in the polar jet stream is expected to plunge temperatures anywhere from 10-20 degrees below average for more than 200 million Americans.

The colder conditions will also create the potential for light to moderate snow across that region beginning Sunday, the first of the season for many.

Weather pattern has potential to bring first snow of season

While air temperatures will plummet, water temperatures across the Great Lakes will remain warm, creating the potential for lake-effect snow for places like Grand Rapids, Michigan, Cleveland and Buffalo, New York.

Snow could also fall across interior parts of Maine, as well as, New Hampshire and Vermont.

The FOX Forecast Center said specific rain and snowfall totals from computer forecast models will come into better focus over the next few days.
