| Episode Narrative | Widespread wind and tornado damage occurred in central Iowa as a result of a low pressure system that raced across the state. Originally, the low pressure center developed in eastern/southeastern Colorado late Tuesday/early Wednesday and proceeded to quickly move east-northeast across Kansas before taking a more northeasterly turn as it approached southwest Iowa. Throughout the event, MUCAPE values were generally in the neighborhood of 500 J/kg. Shear values were supportive with 0-1km values and 0-6km values around 35kts and 85-90kts respectively. SRH values were also very supportive with 0-1km and 0-3km values around 350 m2/s2 and 500 m2/s2 respectively. With the speed of the system and the ample support, resulting storms were fast moving, in excess of 40mph, and of the low topped supercell variety before transitioning into a linear system as the event progressed. |
| Event Narrative | This tornado crossed three counties in southern Iowa. This is segment three in Union county. This long track tornado damaged a number of farmsteads along its 22 mile long path. The tornado was at its strongest in NW Ringgold County where EF-1 damage was found. The beginning and end sections of the track were narrow and intermittent. The narrow tornado also clipped the town of Clearfield to the NW early in its life. |
