The Deep South is immersed in a cold flow of air, and the chill will persist through Monday morning. Not until Tuesday will a milder southwesterly wind allow temperatures to rebound to normal.
Though it's quite chilly with sub-freezing temperatures due across the interior of the northern third of Florida Sunday night, it's not nearly as cold as it could be this time of year. Here are some of record lows for the first week of March: Tallahassee 20, Jacksonville 23, Gainesville 22, Tampa 29, Orlando 25 and Fort Myers 33. None of these records will be touched Sunday night.
The rest of the Southeast will have low temperatures in the 20s Sunday night but that's not terribly unusual for this time of year.
The daylight hours won't be much kinder to the locals. Throughout the Southeast highs in the 40s and 50s will be common place Sunday and one will have to be south of Tampa to have highs in the 60s. But even 60s, which are quite pleasant in the mid-Atlantic in early March, are well below normal in the Sunshine State.
Turning the page to next week Tuesday will be noticeably warmer especially from Georgia southward. To the north however, it will remain on the cool side early in the week and another shot of cold will hit the the Carolina region Wednesday. That next surge of cold air will be accompanied by snow late Tuesday night and Wednesday morning. Eastern Tennessee and western North Carolina could get a few inches then and up to a foot of snow will fall on the Smokey Mountains.
The system bringing the snow is the one that will cause widespread travel delays and cancellations in the Midwest Tuesday and the central Appalachians and mid-Atlantic Wednesday. This storm is not likely to turn up the coast which means New England probably won't get this one. More about this big storm can be found in this news story.
