AccuWeather meteorologist Brandon Buckingham explained that on sunny days—particularly during stretches of calm, clear weather—sunlight can break down smoke and haze in the atmosphere, causing it to sink towards the surface and increasing the likelihood of ozone action days or air quality alerts.
An air quality advisory is in effect until 12 a.m., Saturday, June 7, as Michigan continues to see effects of Canadian wildfire smoke.
