Most rain can ruin a clean car, but the rain Wichita received over the weekend did more than dull a shine, it coated most everything with drops of dirt.

Pictures sent to us by viewers like Tim, show his car and the top of his trash bin covered in the dusty drops.

What causes dirty rain? For starters, blame the Kansas wind. The winds the night before the rain were 40 to 50 miles per hour.

The dirt gets thrown into the atmosphere and when rain begins to form, it throws the dust back down along with the rainfall.

For a raindrop to form, it has to form around something like a grain of sand or a particle of dirt. That's what happened. We had it form around a particle of dust, it went down to the ground. It hit cars and houses, and turned into dirty rain.

Thanks to meterologist Blake Smith for the explanation to this good question.
