Snow falling from a clear blue sky in Michigan

Take a look at this short video. Can you see the little snowflakes falling? Ordinarily, this wouldn’t be any big deal (especially compared to what’s coming Monday night). However, these snowflakes were falling out of a clear blue sky! That’s right, there was not a single cloud from horizon to horizon. The air was calm (so they weren’t blowing off the roof or trees), and the temperature was 10 degrees (-12 degrees Celsius).
