Due to wildfires burning in the Western United States across several states and also in Canada throughout a few Provinces, thick smoke clouds from such fires have moved into Colorado and as far east as Illinois and Ohio. The smoke has created unique atmospheric conditions throughout the state of Colorado, especially along the I-25 urban corridor from Colorado Springs to Fort Collins.
