Smoke returns to the Front Range

 A hazy, smoky sky over the Front Range region Tuesday morning. The vast majority of this smoke originated out-of-state in Utah and Arizona.  Fortunately for folks in Denver, Boulder, Ft. Collins, Greeley, and elsewhere along the Front Range, fine particulates are at moderate levels and shouldn't increase much more from where they currently are.  In fact, as the atmosphere heats up we should see smoke levels decrease late Tuesday morning and continuing through Tuesday afternoon.  In the meantime, you may want take it a little easier than usual Tuesday morning until the air quality improves.

  1. I appreciate the front range update and outlook. Thank you. As someone with lung disease it helps me plan my outside activities. It seems we have been seeing some moderate levels of fine particulates come and go recently in Denver and I was wondering if they were a result or the wildfire smoke.

    1. Thank you for the kind words. It's been a bit of a mixed bag here on the Front Range this summer. At times, the elevated fine particulates have come from wildfires. However at other times, it has been from locally produced pollution (auto traffic, industry, etc.). It is continually changing.
