Saturday is looking like a hot day with forecasted high temperatures in the 90s. Southeast winds will be strong with potential max wind gusts nearing 50 mph for northwest South Dakota. Sunday will be another hot day with potential highs in the 90s and the wind won’t be as strong.
Scattered severe storms capable of large to very large hail, severe wind gusts, and perhaps a tornado or two are possible across the northern Plains. Initial storm development is expected by mid afternoon along the western fringe of the instability across southeast Montana and northwest Wyoming. As a cold front moves into South Dakota, thunderstorms will move through as well. Stay weather aware Sunday and be prepared for passing strong storms.
