Keep an eye out in the area from York to Utica and up around I-80. There is broad rotation (circled below) starting to increase. Giant hail is also possible along U.S. 81 between York and Stromsburg that are moving east northeast.
I'm seeing some pretty significant rotation north of Dodge. If you live in West Point, Beemer or the surrounding area, please be prepared to take immediate safety precautions if it appears threatening.
A line of thunderstorms with high winds and very large hail (egg size) is rapidly developing and threatening eastern Nebraska.
