Sioux Falls, S.D. – Spotters in northwest Iowa have reported funnel clouds Sunday evening as scattered showers continue to track across the region. While these funnels are typically weak and short-lived, residents across southeastern South Dakota, northwest Iowa, and southwest Minnesota are being urged to stay alert until nightfall.
According to the National Weather Service in Sioux Falls and Des Moines, atmospheric conditions remain favorable for brief funnel cloud development through 8 p.m. Sunday. These funnels usually extend only a few hundred feet from the cloud base and rarely touch down, but residents are advised to move indoors if they feel threatened.
Reports of funnels have already surfaced in Lyon, Osceola, and Dickinson counties in Iowa, with additional activity possible across Plymouth, Woodbury, and Cherokee counties, including Sioux City and Storm Lake. Communities such as Huron, Mitchell, and Sioux Falls in South Dakota, along with Worthington, Minnesota, remain within the watch area as evening showers persist.
While no damage is expected, forecasters recommend seeking shelter if a funnel cloud appears overhead. The National Weather Service reminds residents to report sightings, and warns that a tornado advisory could be issued if conditions intensify.
