Well, now I'm angry at spring.
Last night, Grand Forks reported a low temperature of -14. Not only was this a record low for the date, but it was a full 13 degrees off from the forecast low of -1. Needless to say, someone overlooked something. I'm not going to go off on it anymore, because even I don't know what happened, but seriously. -10s in the second half of March?
Edit: Radiational cooling sucks.
