| Episode Narrative | Severe thunderstorms tracked across much of eastern Iowa and northwest Illinois in the early afternoon hours of May 23rd, 2020. Storms quickly intensified in an extremely favorable environment, which was the result of a warm front lifting north across the Midwest. Seven tornadoes were confirmed from this event across Iowa and Illinois. |
| Event Narrative | A tornado caused outbuilding, grain bin, and tree damage at a farmstead in northeast Johnson County. The tornado then followed an intermittent northeast path for 7 miles, and crossed into Cedar County just south of the Cedar River. The tornado downed power poles east of Sutliff. The damage in Johnson County was rated as EF-0, with maximum winds around 85 mph. The tornado rating in Cedar County was EF-1, with maximum winds around 110 mph. Johnson and Cedar County Emergency Management provided assistance in completing the survey. |
