Outlook
The air quality has improved slightly as valley inversions weaken with colder air in the mountains. However, high pressure is still in charge and that's going to mean dry weather and decreasing air quality again. Expect moderate to unhealthy aq for the next several days. A cool down midweek could help with the bad air, but conditions remain dry. The weather pattern looks to shift late next week to help bring a slight chance of mountain snow. - Kristen Van Dyke, KSL Weather 1.17.26
