Cold temperatures in the Midwest and Northeast will sneak as far southward as northern Georgia to start the week.
On Sunday night, chilling temperatures from the Midwest will dip into Tennessee, North Carolina and even northern Georgia.
The threat for a freeze, and even frost, will shift eastward for Monday night into the Northeast and mid-Atlantic.
More southern cities that will be affected include Washington, D.C.; Baltimore, Maryland; Richmond, Virginia; and Charlotte, North Carolina just to name a few.
Temperatures will plummet into the lower 40s south of the Mason-Dixon Line, bringing temperatures that will feel more like the beginning of April, rather than May.
As a result, precautions should be taken to protect warm-season plants that have already been planted.
