I have a question to pose for those who have seen it all. I'll start by stating that I was flying today at 2500' with clouds about 1000 or 1500 above me. I was moving along fine, and I see something just to the left of my path, and it is difficult to describe, and the pictures didn't turn out....It was a cloud to ground area of something. I can best describe it as looking like a small localized rain shower, except it was brown.... It was over a farm field that appeared it might be dusty. This was also occuring in a "less populated" area. I have about 300 hours flying now in Minnesota, and this one caught my eye quick. I deviated and stayed about 15 miles from this spot. This was definitely something I hadn't seen before.
What could cause this?
Small twister, updraft, or some small local phenomenon.

This was one day after the tornadoes they are talking about, the day was fairly stable, and the cold front had already moved in. I could see an updraft causing this but I doubt downdraft, because it was very fixed in shape, like a rainstorm has edges...

No, this wasn't a shadow, I have seen plenty of those. This was different, and really caught my eye. I am now told that that my rear passenger has a picture, I'm not sure of the quality, but I will post it ASAP.

As a meteorologist, I'd be curious to see what pictures you have because I'm not entirely certain what you might be talking about, however my guesses would be dust devil or land spout as Rampart said. Dust devils are very common out west here in drier areas where low level stability can be very low due to a super adiabatic layer near the surface about some dark colored farm lands but the deeper layer wouldn't support any such development.
