Sunset On A Storm

It stormed last night in Minnesota.  My house only got a small amount of rain but you could tell something was going on somewhere because suddenly there was a very eerie yellow/orange cast outside and the clouds looked like this:

The sun was setting on some very disturbing clouds.

Turns out after some research today, that these are mammatus clouds.  They come as a tornadic storm is ending and there were deadly tornados just south of us.
