Yesterday afternoon brought some very interesting storms to Northcentral Iowa. The featured image is of a landspout near Dayton (Webster County) and the NEXRAD reflectivity during that time. These funnels form during the initial storm updraft stretches atmospheric spin in the vertical. These funnels are brief and not all of them reach the ground. Here is a collection of other funnels from Thursday.
