What does May snow bring?

You know the saying April Showers bring May flowers?  Well I want to know what May snow brings.  Yep, that is right, snow.  We are forecasted to get 1-2 inches overnight.  Yuck.  The good news is that it will be just barley freezing, so it shouldn't stick around long. But what in the heck is up with that?

I guess this is Minnesota.
