It was -22F here this morning. But one of the nice things about frigid air -- it's DRY. That means two things. One, damp sticks to you, dry doesn't (entrainment doesn't work as well). Second, there isn't enough capacity in the air to form clouds, so it's SUNNY. Which makes it feel warmer (radiation) and lifts your spirits. I'd rather have 10 degrees, sunny, and dry than 29 degrees, damp, and cloudy.
