Tornado in Boone County, Iowa

This tornado continued into Boone County from Polk County. This tornado was observed via a TDS on the WSR-88D radar and it remained in rural cropland for the duration of its path in Boone county before lifting. No damage was observed to any damage indicators via the ground survey, hence the EFU rating.

Showers and thunderstorms developed along a cold front in the early morning hours, with quarter sized hail and a few stronger winds gusts reported in central Iowa around sunrise. This pushed east of the area by mid morning and temperatures warmed. This allowed for deep mixing and non-thunderstorm associated wind gusts of 50 to over 60 mph occurred across the area through the afternoon. In the evening a secondary front passed across the state, with daytime heating allowing for more robust convection to develop. The bowing, linear storm system primarily produced a swath of wind gusts and damage, however a few smaller hail reports were made.
