This is an important message from our team at Michigan Storm Chasers. Just the facts. Our air quality begins to dip across the majority of the state as we head into the mid-afternoon hours today, July 15th, 2026. By sunset tonight, nearly the entire state will see 150+ μg/m³ AQI concentration, which translates to very unhealthy on the air quality index. Overnight, those winds out of the northwest do not stop, bumping parts of our area into the hazardous to everyone category at 250.5-500 μg/m³ AQI concentration if recent short-term model trends are correct.
Dangerous air quality levels like these are rare, so please take your respiratory health very seriously. Smoke concerns mixed with the already excessive heat concerns both today and tomorrow will also be a factor for higher mortality rates amongst all age/health groups, per research collected by the National Library of Medicine (NLM). All data shown is for fine particulate matter (PM2.5).
Follow along for updates. Outdoor activities beyond this evening should monitor the AQI very closely.
