A brief tornado formed just south of 500N Road and west of 1000E Road southwest of Cissna Park. This tornado caused damage to the roofs of a farm outbuilding and a large storage building as it moved northeastward, depositing debris downstream to the east/northeast over empty farm fields before dissipating just west of Cissna Park.

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph

When a tornado is known to have occurred but does not cause damage to any qualified damage indicators, or if the only damage is located in an area that is inaccessible to NWS storm survey personnel, then a tornado may be assigned the EF-Unknown (EF-U) rating.
