South Dakota – A cold start near 29°F gives way to a fast-changing sky, with clouds thickening and rain edging closer by late day.
The air feels crisp early, but that chill fades quickly as temperatures climb into the low 50s. By mid to late afternoon, scattered showers begin developing, first light and spotty, then expanding into the evening.
According to the National Weather Service, isolated storms are possible today, though severe weather is not expected initially. The bigger concern builds into the weekend, when stronger storms may develop across eastern South Dakota and nearby Iowa and Minnesota.
Drivers along I-29 should watch for shifting conditions. Dry roads can quickly turn slick as showers move in. Keep headlights on and allow extra stopping distance.
Friday trends warmer, with highs pushing near 58°F and more sunshine early. But clouds increase again, and rain chances return late, especially after sunset. Conditions stay manageable, but roads may turn damp again into the evening commute.
Saturday marks a noticeable shift. Showers become likely, with a 70% chance of rain and embedded thunderstorms by afternoon. Winds pick up, and brief downpours could reduce visibility quickly.
By Saturday night into Sunday, storms continue with a 50% chance of thunder. Breezy conditions develop, and highs surge into the low 80s Sunday, giving the region a brief taste of early summer before more rain chances return.
Looking ahead, the pattern stays active into early next week, with additional rounds of showers and storms possible. Some of these could strengthen depending on instability trends.
Plan ahead for weekend travel and outdoor plans. Conditions may change quickly after sunset Saturday.
