Forecast Discussion
A cooler, drier air mass will settle over Michigan following Thursday’s clouds. Friday will feel refreshing, with highs near 80°F and no wildfire smoke in the region—setting the stage for excellent air quality to begin the weekend.
Saturday brings a chance of thunderstorms and potential severe weather. Morning showers could reduce afternoon storm intensity by limiting instability. However, if the morning stays dry, the likelihood of stronger afternoon storms increases. Regardless, Saturday is likely to be wet.
Sunday will see a return to sunny skies and comfortable temperatures in the low 80s, accompanied by light north-northeast winds. Air quality is expected to remain mostly Good for both ozone and fine particulates.
Looking ahead, summer weather returns midweek, with temperatures possibly reaching the low 90s and continuing into the following weekend.
Extended Outlook
Air quality is not expected to be an issue as the upcoming work week begins.
