Friday Funnel Fest

Posted: 11 Jul 2026 10:27 AM, Views: 163
After numerous funnel clouds were reported over Iowa on Thursday, Friday saw even more funnel clouds reported with even a few reaching the ground as brief tornadoes. This is a favorable time of year for such events as strong instability, low cloud decks, and weak wind shear allow for updrafts to stretch atmospheric spin into tighter vortices. The featured lapse is from the KCRG-TV webcam at the University of Northern Iowa (Cedar Falls/Waterloo) showing a brief funnel cloud during the afternoon hours on Friday. As a reminder, the IEM attempts to curate interesting webcam lapses of weather onto YouTube with the featured lapse found here. And for those of you that like pretty sunsets, this one from Peosta is for you!
