A frigid airmass is bringing "sharply colder" weather across the eastern two-thirds of the country, with maximum and minimum temperatures between 20 to 30 degrees below average expected to break many records across the Southeast through Monday night, Nov. 10, the National Weather Service said.

The weather service said freeze watches and warnings are in effect from the Lower Mississippi Valley to the Virginia Tidewater through Tuesday morning, with winter weather advisories in effect across multiple states, including portions of Ohio, Wisconsin, Virginia, Tennessee, Illinois, Indiana, and New York, among others.

According to AccuWeather's latest forecast, a "significant round of snow" is likely from the shores of Lake Superior to Lake Ontario, affecting areas such as Chicago, Cleveland, Buffalo, and Pittsburgh, among others.

"This storm pattern will introduce some of the coldest air seen for early November, and that is the reason for the robust snow amounts expected in the Great Lakes and the far southern extent of the flurries into the southern Appalachians," said AccuWeather Senior Meteorologist Chad Merrill on the site's morning forecast for Monday, Nov. 10.
