Snow will be possible as far south as Atlanta on Tuesday.
A blast of Arctic air is heading for the eastern and southern USA. Temperatures on Tuesday and Wednesday will be more typical of January than November, thanks to a powerful cold front now heading for the East Coast.
The cold air was already barreling into the northern Plains, upper Midwest and Great Lakes states Monday. As of midday, the temperature was a nippy 14 degrees in Bismarck, N.D., and 3 inches of snow had fallen in parts of southeastern Minnesota.
In fact, snow was flying Monday all around the upper Midwest and Great Lakes. Cities such as Chicago, Syracuse, Indianapolis and Pittsburgh could all see a coating to an inch of snow by late Monday. Snow will be heavier along Lake Erie from Cleveland to Buffalo.
The season's first snowflakes are possible in the Northeast, Mid-Atlantic, middle Mississippi Valley, lower Ohio Valley and Tennessee Valley Monday night or Tuesday as the front passes by, said Weather Channel meteorologist Kevin Roth, who added that most of it won't stick to the ground.
A few flakes are possible as far south as Atlanta on Tuesday night.
High temperatures on Tuesday from Washington, D.C., northward to Philadelphia, New York City and Boston will fail to get out of the 40s, while nighttime temperatures will drop below freezing, AccuWeather predicted.
Overall, by midweek, temperatures are forecast to be from 15 to 20 degrees below average all the way from the Plains to the East Coast and northern Florida, according to Roth.
A few daily record lows are possible in parts of the Northeast and Southeast on Wednesday night and Thursday morning, Weather Channel meteorologist Chris Dolce said.
Temperatures Wednesday night will dip into the mid-30s as far south as Florida, reports the National Weather Service. Freezing temperatures are likely all across the Deep South on Wednesday night.
Luckily, AccuWeather meteorologist Anthony Sagliani reported that this winter chill will not be sticking around for very long. Temperatures will be warming back toward more seasonable levels by the weekend.
