Wildfire smoke causes air quality concerns across North America.

Denver will have isolated storm chances over the weekend with highs in the 70s, while the wildfire smoke from Canada will continue to bring poor air quality to parts of Colorado. An air quality warning is in place through 4 p.m. Saturday, but conditions should improve Saturday evening. Temperatures will hit the low 70s on Saturday with scattered showers and storms in the afternoon, but Denver only has a 20% chance for storms. Storm chances will increase to 40% in Denver next week with temperatures staying in the warm 70s through next Friday.
