Inversion.
It happens every winter, and a lot of you dread it for good reason! As cold air stays trapped in the valleys by a layer of warmer air above it, pollution builds until a change in the weather helps ventilate it out. Unfortunately, this time around that doesn't look like it's going to happen anytime soon.
A storm dropping through the plains late this week won't make a direct hit on Utah, but will bring slight cooling that might weaken the inversion. It doesn't look like it'll be strong enough to break it up.
As high pressure builds again next week, inversions will continue with decreasing air quality & visibility. Patchy overnight & morning fog will also become likely. Fingers are crossed that a storm late next week will break up the inversions and bring some much-needed snow.
