What happened
The episode as NWS DMX wrote it up.
A large area of thunderstorms lifted north across Iowa during the day on the 24th. The storms were north of a warm frontal boundary in an area of strong warm air advection. The atmosphere was tropical in the sense that the sounding was nearly saturated through the column. One storm became quite strong, but remained below severe levels for several hours as it tracked from west central into north central Iowa. The storm became severe as it moved across Franklin County. In Franklin County, a microburst took place in the Hansell area. Winds were estimated near 100 MPH with considerable damage in the area. Power poles were blown down, several hog containment buildings were destroyed, and one machine shed was destroyed. Sheet metal was blown downwind 3 to 4 miles.
