Even in both of those winters there were fairly long stretches of mild weather. Much of January 2010 was mild after the first week until we saw the pattern change in the last few days and we had a major storm as soon as cold returned. Even as good as February 2014 was KCLT still ended 1 degree above average for the month. In my memory, I don’t think any winters had true wall to wall cold in the southeast in my memory… I do hear people talk about ‘76-77, but that’s to far back for me to remember, even still if one were to look up the data that winter probably has some mild periods as well… we are in the south after all.
