Confusing Weather

The weather, as my subject says, is confusing the hell out of me. High yesterday was in the mid 40's. About normal for this time of year in GA. However Saturday the high was 40, and snow was predicted (but did not materialize), and it's currently 66. The TV says it's supposed to fall to 55 later today and then drop to 29 tonight. Huh? That's a pretty big change - like a 40 degree change! Tomorrow things are supposed to be normal again - high around 45. I kind of hope it stays normal. Switching between wearing t-shirts and sweatshirts is getting annoying.
