Scattered severe thunderstorms capable of large hail and wind gusts will remain possible mainly across the Dakotas into Minnesota. ...Northern Plains/Upper Midwest... Severe thunderstorms including some supercells will continue to focus this evening across the Dakotas, primarily across south-central/eastern North Dakota as well as north-central/eastern South Dakota, while also expanding into parts of Minnesota tonight. Bouts of large hail will remain possible along with severe-caliber wind gusts.

A few strong/locally severe storms could still occur this evening, but overall storm intensifies are expected to continue to wane with the loss of daytime heating. ..Guyer.. 07/20/2026 $$
