After a period of thunderstorms tonight, an additional, brief round of showers and thunderstorms is expected to develop over central Iowa by late morning into midday and then quickly race north and east into eastern Iowa during the afternoon. The storms won’t last long at any particular place due to their very fast movement, but the stronger storms may still produce large hail, damaging winds, and a few tornadoes.
