      Mayfly invasion caught on radar

      Mayflies making a mess across portions of Wisconsin and Minnesota on Sunday night.

      Doppler radar can detect rain, hail, wind speed and direction, and some other unwelcomed flying objects.

      On July 20th near LaCrosse, Wisconsin, the local radar detected mayflies emerging from the Mississippi River.

      For a look at the radar loop from that evening and some amazing and even scary pictures of the mayflies, click here.
