One More Frosty Morning Across Mid-South, East

April 23, 2021
UPDATED By WeatherBug Meteorologists
One more morning of unseasonable cold temperatures is on tap across the Eastern U.S. With the growing season underway, this Spring freeze could be bad news.

A cold and dry airmass is locked in place across the central and eastern U.S. This will force temperatures to run 10 to 15 degrees colder than normal from Texas into the Northeast, including the Southeast. 

Morning lows today will be in the upper 20s across the northern and western high Plains and extreme northern New England. The lower Midwest, Ohio and Tennessee valleys, southern Appalachians, western Carolinas, interior Mid-Atlantic and the rest of the Northeast will have lows in the low 30s, with rural locations, especially lower elevation valleys, seeing temperatures drop into the 20s. The coastal Southeast, South, central Gulf Coast, northern Florida will have a chilly night and morning with lows in the 40s and lower 50s.

Freeze Warnings and Frost Advisories stretch from western and central Ohio and the upper Tennessee Valley eastward to the southern Mid-Atlantic Coast.

With the growing season started in many parts of the U.S., these cold temperatures could damage sensitive plants. If you can, plants should be brought inside. Otherwise, cover them with plastic to minimize damage. Warmer weather arrives this weekend with only the far northern tier of the U.S. seeing low temperatures dropping below freezing.

Record lows from this cold snap have already been set. Oklahoma City dropped to 29 degrees Wednesday morning, breaking an old record of 34 degrees set in 1966. Dallas also dropped to 37 degrees, falling below the 39 degree record set over 100 years ago in 1918.
