August 31, 2026

Minnesota is starting the new week with warm temperatures across much of the state, with the best chance for stormy weather staying in southern Minnesota. Northern and central parts of the state should see a quieter stretch through midweek, while the south deals with a greater chance for thunderstorms before conditions settle down later in the week. Based on forecast details for Duluth, St. Cloud, and Rochester, the overall pattern points to warm air holding across all three regions through Wednesday, with the south staying the most unsettled.

Northern Minnesota

Northern Minnesota looks to stay warm Monday and Tuesday, with highs both days near 84 degrees and overnight lows around 58. Monday brings a partly sunny sky, followed by very warm conditions Tuesday. By Wednesday, the north cools off a bit, but sunshine is expected to dominate with highs in the mid-70s.

Central Minnesota

Central Minnesota is also in for a warm and fairly quiet three-day stretch. Monday will be partly sunny with a high around 85 and a low near 56. Tuesday stays warm with sunny spells and a high again near 85. Wednesday cools slightly, but mostly sunny skies are expected to continue with highs near 81.

Southern Minnesota

Southern Minnesota will be the part of the state to watch for changing weather. Monday brings the chance for morning thunderstorms, with some storms capable of heavy rain and strong wind gusts. Highs should reach around 90. Tuesday stays very warm, with another chance for afternoon thunderstorms and a high near 89. By Wednesday, the storm threat backs off some, but it will remain warm and humid with highs in the upper 80s.
