National Weather Service Storm Prediction Center outlooks on September 14 placed a slight risk of severe thunderstorms, including tornadoes, across eastern Nebraska into western and central Iowa, with a Tornado Watch covering that corridor through midnight. Favorable parameters included moderate instability, strong low-level shear from a 40-50 kt jet, and supercell potential, though lingering inhibition created some uncertainty about surface-based storms. Omaha, Lincoln, Des Moines, and Sioux City sat within the highest-probability tornado contours. An isolated EF-0 tornado occurred earlier in Virginia, outside the main risk area. Updated model runs and real-time radar data from SPC and local NWS offices determined final city-level impacts for market resolution.
