Wacky Weather

I know this is Michigan, but what gives?? Monday night, I got out of work at midnight, drove home, no coat, was a bit chilly, but not to bad. Wake up and there is a crapload of snow coming down Tuesday morning. Now, it's Wednesday evening, and the temp is 78 degrees outside. It goes from 60's one day, to 30's the next, then almost up to 80's the day after. I'm surprised there weren't any tornados.
