Mayflies in July
25 Jul 2018 05:35 AMIt is that time of year for the Mayflies along the Mississippi River. The featured RADAR animation is from the La Crosse, Wisconsin site Tuesday evening between 8 and 10 PM. You can see the reflectivity returns light up along the river. The further south you travel away from the RADAR the higher the beam is, so it is likely missing the activity. The tracking of Mayflies via RADAR is well documented and NWS La Crosse even has a webpage dedicated to the topic.
