(Des Moines, lA) -- Canadian wildfire smoke is back in Iowa.
It's making the blue sky milky white and creating a faint haze on the horizon.
The U.S. EPA reports that the northwest half of Iowa is getting a heavier plume of smoke. It starts at the northwest edge of the Moines metro. It extends diagonally across the state, lowering breathable air quality from Council Bluffs through Sioux City, Ames, Mason City, and Decorah.
The southeast diagonal half of Iowa is better off, with the wildfire smoke staying higher in the atmosphere. Air quality remains good in Cedar Rapids, Iowa City, Dubuque, and the Quad Cities.
