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.
I would love to hear your thoughts.
