Drastic Temperature Change For Midwest, East

A new sweep of cold air will race across the Midwest Sunday and will reach the East and South later on Monday.

While the invading cold air will not be as frigid as last week, it will shave temperatures by 20 to 30 degrees Fahrenheit off weekend highs in the 60s and 70s in the Midwest and East.

The colder air will follow a dose of rain, damaging winds and severe weather across the Midwest this weekend and the Appalachians and Northeast Sunday night into Monday.

The core of the Arctic air will stay north over the Canada border over the Plains and generally north of the Great Lakes and the St. Lawrence Valley farther east. However, it will get cold enough for a round of lake-effect snow.

The combination of wind, chilly air and other factors will make for RealFeel® temperatures 10 to 20 degrees lower than the actual temperature from the Upper Midwest and Northeast, southward along the Atlantic coast to part of the Deep South.

Temperatures are likely to dip to near freezing along the I-40 corridor from Tennessee to North Carolina Tuesday and Wednesday night.

Farther north, nighttime temperatures will be near freezing around Boston, New York City, Philadelphia and Washington, D.C., Tuesday night and Wednesday night.

The new blast of cold air may be more abbreviated than the last one and will generally only last a day or two in most areas, before temperatures rebound again.
