OMAHA, Neb. (AP) — Forecasters are warning that strong thunderstorms and possibly tornadoes could develop in eastern Nebraska and Iowa this afternoon. The National Weather Service says there is a moderate risk of severe weather in the area through tonight. A tornado warning was issued at midday for south-central Iowa and there were reports of strong winds and quarter-size hail near Osceola.

The weather service says parts of central and northern Kansas, southeastern Nebraska and most of Iowa are likely to see strong thunderstorms, large hail, strong winds and tornadoes.

Yesterday, heavy storms and at least one tornado hit northwestern Missouri, damaging homes and power lines. No injuries were reported. The National Weather Service said a confirmed tornado hit the Ray County town of Orrick last evening.
