Couple the wildfire smoke with 100-degree temperatures, and it made for quite a miserable Monday. The smoke was so bad in the past 24 hours that it registered Denver, Colorado, on the list of one of the worst locations in the world for air quality. Thankfully, at the time of writing this, the air quality has improved across the Front Range of Colorado. However, we are still under an Air Quality Alert from the National Weather Service. Front Range Remains Under Air Quality AlertThe Air Quality Alert was issued at 9 a.m. on Tuesday morning, through 9 a.m. Wednesday.
