Heavy Rain in a Short Amount of Time in Ames, Iowa

Iowa Radar Estimated Rainfall

A couple outflow boundaries this afternoon collided with one another along the highway 30 corridor late this afternoon. This allowed for rapid thunderstorm development, which eventually lead to flooding rain. In a matter of 10 minutes, the Ames airport reported 1.07″ of rain. Almost 40 minutes later, at 5:37PM CDT, the Ames airport was up to 2.89″ of rain, and it was still raining.

Since the rain has stopped, rainfall reports of over 3 inches are coming in. At 6:01PM CDT, the Ames airport recorded 3.42″ of rainfall. A short time later, at 6:13PM CDT, Ames emergency manger reported a foot of water over Airport road, just on the south side of Ames.

On the Iowa State University Campus, a large tree split due to the high winds that accompanied this complex of storms.
