The Pinpoint Weather Team said heat will not be the only issue in the state this week, there will also be smoke from wildfires in other states.
Meteorologist Chris Tomer said the smoke started moving into the state on Monday and could persist until Thursday.
The Rocky Mountain Area Coordination Center said the smoke is from wildfires burning in Idaho and Montana.
If you are unusually sensitive to smoke, the Colorado Department of Public Health and Environment said to consider reducing prolonged or heavy exertion in areas where smoke is apparent.
