A few strong to severe storms may form over northern South Dakota and drift southward late Monday evening into the early overnight hours. Generally the greatest risks will be from strong gusty winds.
Although details remain uncertain, strong to severe storms are possible again late Tuesday evening into early Wednesday morning. Main threat will be strong winds, but large hail and locally heavy rain are possible as well. Keep an eye on the forecast, and have multiple ways to receive warnings.
Scattered thunderstorms will again be possible during the first half of the week. A few of these storms could be strong to severe. By the end of the week, we'll be watching the heat build. By the weekend widespread highs in the 90s and even 100s will be possible.
