While wildfire activity remains pleasantly quiet in Colorado and fine particulate levels continue to be in the Good to Moderate range, our neighbors to the north and west are still contending with areas of thick smoke from fires in Wyoming and Idaho. The heaviest smoke remains in the areas close to the fires, blanketing central Idaho and northwestern Wyoming.

With an atmospheric ridging pattern over the mountain west, upper-level winds will likely carry much of the heaviest smoke to the north and east of Colorado, however light to moderate concentrations of smoke from the fires closer to us may filter into northern and eastern portions of the state over the next several days.

No significant public health concerns due to smoke are anticipated at this time, with this pattern likely to stay in place through the coming weekend. Overall, we expect hazy skies and light to moderate concentrations of fine particulates, primarily in northern and eastern areas of Colorado.
