There are about half a dozen recording stations within 15 miles of me that show up on weatherunderground. The variance in temperatures reported is significant, 5 degrees is not uncommon. Micro-weather or something I suppose.
The larger picture is that you slept through a night that (except for wind and humidity ) is about as cold as you're likely to see on the AT in March, and were comfortable.
I'm a bit envious, forecast for night-time lows around here are in the upper 20's for the next week and a half.
