Summary: A broken band or two of strong-to-severe thunderstorms will move from eastern Nebraska into western Iowa and northwest Missouri later today, with additional storms forming in the wake of these across south-central Nebraska. Other storms should form/strengthen northward from northeast Nebraska into southeast South Dakota and southwest Minnesota. Some of the activity, especially in Nebraska and western Iowa, will be capable of large hail, damaging winds, and possibly a tornado or two through early tonight.
Remember, a Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes.
