DENVER – Forecasters with the National Weather Service said Thursday that Coloradans should expect smoke from North American wildfires to persist in varying degrees through the early fall.
While some of the haze lifted briefly Wednesday afternoon and Thursday morning, the NWS says Colorado will see wildfire smoke return Thursday afternoon.
A NWS meteorologist in Boulder said that winds are bringing the smoke from fires burning across the West, Pacific Northwest, and western Canada into Colorado. Satellite imagery shows how the smoke is traveling to the area.
Where's all the smoke coming from? The Primary source of smoke over the NW USA is originating from over 100 active wildfires in wrn Canada. Dozens of wildfires in N CA, OR & WA are also contributing.

The Colorado Department of Public Health and Environment said the smoke could worsen late Monday into next Tuesday and that “unusually sensitive people” should consider staying inside.
Scientists and researchers from Colorado State University have been leading the WE-CAN smoke sampling team. The group is based in Boise, Idaho and has been flying through western wildfire smoke this summer to study how the smoke's composition and how it impacts air quality.
