Big changes are on the way for Minnesota’s weather patterns in the next week.

If you like variety, you’ll enjoy the latest 7-day forecast. Over the next week, we’ll see sunny days near 70 degrees, showers, and our first shot of real summerlike heat and humidity next week.

Showery Wednesday

We begin with some light rain Wednesday as a warm front triggers scattered showers. NOAA’s NAM 3 km resolution model paints the shower zones moving across Minnesota from west to east Wednesday.
