Farther north, Philadelphia could see the coldest Saturday morning since 1976.
“It (will) feel more like the middle of winter rather than early November in some places,” says Accuweather.
By Friday the chill will penetrate into the Deep South. with afternoon highs 10-20 degrees below normal for early November across the Southeast.
“The low temperature could plunge to 26 F (- 3.3 C) in Philadelphia on Saturday morning. It hasn’t been this cold so early in the season there since 1976,” said Jesse Ferrell, AccuWeather meteorologist.
Potential widespread frosts and freezes across the South
Some upper 20s are likely from Arkansas to northern Mississippi and northern Alabama into the Tennessee Valley on Friday night.
An even colder blast could hit early next week, bringing temperatures 10-20 degrees below normal for mid-November across most of the eastern two-thirds of the nation.
“A widespread killing freeze is likely to end the growing season across much of the South early next week,” said AccuWeather Senior Meteorologist Dan Kottlowski.
Below freezing all the way to the central Gulf Coast
A huge swath all the way from the Dakotas to northern Texas, eastward to the Carolina coast and through the Northeast will likely see temperatures drop into the teens and 20s on Tuesday morning.
The temperature where I live, south of Dallas/Fort Worth, is forecast to drop to 23F (-5C) on Tuesday morning.
