The Storm Prediction Center has issued a Severe Thunderstorm Watch until 11pm for the following counties, Fremont, Harrison, Mills, Monona, Montgomery, Page, Pottawattamie and Shelby. Thunderstorms are developing in eastern Nebraska and will move into the state this evening. Like the watch issued just a few minutes earlier, large hail and damaging straight line winds will be the main threats with an isolated tornado also possible.
