Minneapolis is starting Tuesday near 66 degrees with clear skies, but the calm opening could give way to scattered showers through the morning. The high should reach about 79 degrees before skies brighten around midday, with only a small chance of a shower or thunderstorm late in the day, according to the National Weather Service.

Morning Showers Fade By Midday

Rain chances are highest during the morning commute, with showers possible through roughly 4 p.m. Most of the activity should be light, although an isolated rumble of thunder cannot be ruled out.

Winds will shift toward the northwest at around 5 mph as the front moves through. Rainfall should generally stay light, with forecast amounts between a tenth and a quarter of an inch where showers pass.

Clear Skies Set Up A Sunny Wednesday

Tuesday night brings one more chance for showers or thunderstorms before 7 p.m., followed by mostly clear skies and a cooler low near 59 degrees. Wednesday looks like the week's easiest outdoor day so far, with sunshine, light west winds and a high near 80.

Thursday Brings The Next Storm Chance

Temperatures climb to about 84 degrees Thursday, with a slight chance of afternoon showers and thunderstorms. The National Weather Service discussion also says a few stronger storms are possible Thursday into Friday, while the current forecast puts rain chances at 20% Thursday afternoon and 40% Thursday night.

Friday could begin with a few showers before turning mostly sunny and warm, with another high near 84 degrees. No watches, warnings or advisories are posted for the forecast area.

Mostly Sunny Weekend Ahead

Quiet weather returns for the weekend, with sunny skies and highs near 80 degrees Saturday and mostly sunny conditions Sunday. A slight chance of rain returns Sunday night and early Monday, but Monday should turn mostly sunny with a high near 82.
