High ozone levels, wildfire smoke from out of state will continue to impact air quality in Colorado this week
High ozone levels and wildfire smoke are causing smoky and hazy skies over Colorado, expected to last until at least Wednesday, with potential continuation into Thursday. The haze is primarily due to smoke drifting from wildfires in Canada and the Pacific Northwest, affecting air quality, especially in higher elevations of north-central Colorado. The NWS has issued health advisories for sensitive groups and anticipates rain later in the week.
