 Smoke is lingering on the Front Range this morning. Particulate matter concentrations are Moderate in Denver, Fort Collins, and Greeley. Fires continue to burn in Idaho, Utah, and Wyoming, and smoke could move into Colorado starting Wednesday afternoon.

A cold front is expected to move into Colorado on Wednesday evening, and smoke could arrive alongside it. According to the HRRR-smoke model, smoke may arrive beginning Wednesday afternoon. Counties along the Wyoming border could see smoke by late afternoon, and smoke will continue to push south Wednesday evening, and overnight into Thursday. Northern Colorado could wake up to noticeable haze and smoke on Thursday morning. Smoke may persist throughout the day on Thursday.

It's unclear exactly how much smoke will arrive, but what is clear is that northern Colorado is likely to experience the highest concentrations. Craig, Steamboat Springs, Walden, Fort Collins, Greeley, and Denver could all be impacted. If you are in these areas, you might consider limiting exercise, staying indoors, and keeping your windows shut to minimize your exposure to smoke.

We will update the blog on Thursday as conditions develop.
