From the National Weather Service:

"Severe storm development is underway from northeast Nebraska into southeast South Dakota, and storms will spread quickly northeastward through the afternoon. The storm environment favors a mix of supercells and clusters/line segments, with all hazards
possible. The potential for strong tornadoes will increase through the afternoon toward southwest Minnesota, especially with any discrete supercells. Otherwise, very large hail (near tennis ball size) and damaging outflow winds up to 75 mph can be expected."
