Minneapolis is headed from a dry, sunny Saturday into a much hotter start to the workweek, with heat index values expected to run well into the triple digits from Monday through Thursday. Saturday should stay comfortable by comparison, with plenty of sunshine and a high near 84 in the metro.
For people in the metro, that shift is the reason the forecast matters today. The weekend offers only a short break before the kind of heat that can change plans fast, especially after Monday, when the hotter stretch is expected to settle in and linger for several days.
Sunday will turn slightly warmer, and shower and thunderstorm chances are set to return, but that does not blunt what comes next. Forecast First Alerts are already in effect from Monday through Thursday, and that stretch is expected to bring the most oppressive conditions of the week, with the heat index staying in the triple digits across those days.
The early-week setup also carries a second concern. Monday evening storms will be watched for development, and some of them could become severe. That leaves Minneapolis with a weekend that looks mild and dry, then a fast turn toward heat and unsettled weather just as the workweek begins.
So the answer is not whether the weather will change, but how quickly. Saturday gives way to a brief warmup Sunday, then the metro moves into several days of dangerous-feeling heat and a storm watch Monday evening, with the sharpest climb in heat index values arriving after the weekend is over.
