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.

“Smoky conditions of varying densities are expected to persist through early fall,” the NWS Boulder said Thursday.

According to an HRRR model published by the NWS Pueblo Thursday, northwestern and northeastern Colorado will see the worst smoky conditions Thursday night into Friday morning.

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.
