Detroit, Michigan – Hazy skies and rising humidity will grip Southeast Michigan early this week, with wildfire smoke reducing air quality and storms looming by midweek. Temperatures will push toward 90°F in Detroit, Ann Arbor, and Flint through Wednesday, making outdoor plans risky—especially for those with respiratory conditions.
According to the National Weather Service in Detroit/Pontiac, a pocket of high pressure is locking in dry, warm air for the first half of the week, but Canadian wildfire smoke will trigger ongoing Air Quality Alerts through at least Wednesday. Daytime highs Monday and Tuesday will range from 85° to 90°, with overnight lows in the upper 60s.
Storm chances ramp up sharply by Wednesday afternoon—especially along I-94 and US-23 corridors—bringing a 60% to 70% risk of heavy rain, lightning, and strong wind gusts into Thursday. Cities including Detroit, Ann Arbor, and Pontiac should prepare for localized flooding and brief power outages. The National Weather Service recommends avoiding outdoor work during peak smoke and thunderstorm hours, keeping windows closed, and charging devices ahead of possible outages.
A noticeable cooldown arrives Friday, as a cold front sweeps in, dropping highs to the upper 70s. Lingering showers may affect the morning commute before drier, cleaner air moves in for the weekend. Additional alerts are possible if storms intensify or air quality worsens.
