Midwest US Faces Severe Thunderstorms Across Sioux Falls and Nebraska

The National Weather Service has expanded a Level 3 (Enhanced) risk area for severe thunderstorms across eastern South Dakota, southwest Minnesota, and northwest Iowa. Primary hazards include large hail up to 2 inches in diameter, damaging straight‑line winds potentially reaching 75 mph, and the possibility of isolated tornadoes after dark. Residents are urged to stay alert, use multiple warning channels, and seek shelter in sturdy buildings if warnings are issued.

In southeast Nebraska, forecasters have issued a slight (Level 2) risk of severe weather for overnight thunderstorms. Expected threats are hail ranging from golf‑ball to tennis‑ball size, wind gusts up to 65 mph, and a brief possibility of a tornado north of Interstate 80. Cooler temperatures are forecast for Thursday, with highs in the low 70s to low 80s across the state, offering relief from recent heat and humidity.
