Sounds like MN and SD had some pretty bad storms last night, and you must have been seeing some of it. Hopefully you weren't anywhere near where the most severe damage was. They said there's a small town in SD that was basically leveled but it's still undetermined just waht caused the damage. Don't know how it can't be determined, but I suppose there's all sorts of terms out there now - micro burst, tonado, etc. and they just want to get it right. Either way this poor town is going to have to completely rebuild. They didn't mention any casualties, so hopefully everyone is ok.....
