Severe thunderstorms brought large hail and damaging winds to a few counties in south central Nebraska during the evening of May 8. A cluster of thunderstorms, which included supercells, developed along and just north of the state line between 5-6pm CDT and gradually shifted E through the evening. The strongest activity affected Webster, Nuckolls, and Thayer Counties where large hail and damaging winds were reported. Hail ranged in size from quarter (1.00���) to golf ball size (1.75���), and wind gusts peaked near 70 MPH. The greatest impacts were near Chester in Thayer County where severe wind gusts caused widespread tree damage, power outages, and overturned pivots. Severe thunderstorms pushed east of the area by 9PM CDT, but non-severe thunderstorms continued until almost midnight.
