Tornado in Madison County, Nebraska

The office received photo evidence and eyewitness reports of a funnel cloud with a short-lived ground circulation and dust cloud. A brief tornado was determined to have occurred at this location. There were no damage indicators impacted, so the rating of this tornado is EF-U.

On the morning of the 15th, upper air analysis showed a shortwave trough centered over the High Plains. At the surface, a warm front draped across the Plains slowly lifted north throughout the day, eventually stalling out across eastern Nebraska and down into northwestern Missouri. That afternoon, two areas of thunderstorm development was noted, one in northeast Kansas and another in northeast Nebraska. The thunderstorms in northeast Kansas quickly grew upscale into an MCS bringing strong winds and a brief spin-up tornado to southeast Nebraska and southwest Iowa. The thunderstorms in northeast Nebraska were tied to a lingering MCV, with the storm mode initially remaining as clustered supercells. This brought large hail and several tornadoes across northeast Nebraska before finally growing upscale into a second MCS and tracking east into west-central Iowa.
