If you noticed a brownish grime on your car yesterday in Minnesota, there's a good chance it didn't come from here. Wait, what?

I noticed the windshield of my SUV was coated with a brown grime when I left our parking lot in downtown Rochester yesterday and again when I left early this morning. It was the kind of dust you might see on your car if you drive down a dirt or gravel road in the summer-- the kind of dust that then turns to mud when we get rain, like we did yesterday.

But here's the thing: I knew I hadn't driven on any dirt roads lately. I didn't think too much more about it, I just hit the wipers and cleared it off. Until I saw this post on KTTC meteorologist Mat Benz's Twitter page, that is.

He noted that same kind of muddy grime on his car yesterday too. But he figured out what it might be from-- and it ain't even from here in Minnesota. Matt said that grime might have started all the way down in the desert southwest and then caught a lift in the atmosphere, finally ending up on your car here in the Land of 10,000 Lakes!

"It might be dirt that was picked up with our latest storm system when it was over New Mexico & Texas!" Matt's Tweet said. It's similar to when there are wildfires burning out west somewhere and the smoke is picked up by the jet stream and carried east so we can sometimes smell it here.

So if your car needs ANOTHER car wash today, you can blame it on New Mexico. Or Texas. Because that's not native Minnesota grime you're seeing!
