A stalled out surface low across the area lead to a week of conditions favorable for funnel cloud development. In the afternoon and evening hours of June 25, 26, 27, 29, and 30, funnel clouds were reported across Iowa. 0-3 km CAPE values around 100 J/kg and surface vorticity in the vicinity of the surface low made for a good funnel cloud environment for several days, though there was no report of any tornadic activity with any showers.
