Daily afternoon thunderstorms will remain in the forecast east of the Rocky Mountains and out onto the High Plains. With plenty of heat and moisture, severe thunderstorms will be possible.
Along with ample heat and moisture, strong upper-level winds will continue to overspread the area, both from an upper-low dipping down from Canada and along the periphery of the big heat dome across the central U.S. Friday's SPC risk includes the Dakotas for the threat of wind and hail. An isolated tornado threat is possible too.
More severe storms will be possible across Montana on Saturday. With the repeated rounds of heavy rain, some flooding could be possible.
