Utah’s air quality is going to get worse — but there’s relief in sight

Expect a change in the weather early next week.

(Trent Nelson | The Salt Lake Tribune) Poor air quality obscures the Oquirrh Mountains and downtown Salt Lake City, as seen from the University of Utah on Friday, Dec. 3, 2021. Air quality is expected to decline again over the next few days.

Utahns can expect clear skies through the weekend — and a decline in air quality. But a change is expected early next week.

There’s no precipitation in the forecast through Sunday, according to the National Weather Service. In Salt Lake City highs of about 40 Friday-Sunday, with overnight lows in the upper teens and low 20s.

The bad news is that inversions will build in northern Utah valleys and air quality will worsen. Yellow/moderate conditions are expected, and by Saturday or Sunday some areas could experience orange/unhealthy for sensitive groups conditions, according to the Utah Division of Air Quality.

The good news is that a winter storm is expected to break up the inversion next week. There’s a chance of snow in Salt Lake City on Monday, mostly after 11 a.m., continuing into Monday night and Tuesday. And a cold front will drop temperatures from a high of about 43 on Monday to 35 on Tuesday (about 16 overnight Tuesday) and 31 on Wednesday.

It’ll be even colder farther north. Logan will see highs in the low to mid-30s through Monday, with overnight lows of 6 on Thursday, 9 on Friday, 11 on Saturday, and 15 on Sunday and Monday. And then it’s going to get colder — highs in the mid-20s on Tuesday and Wednesday, and an overnight low of 7 on Tuesday.

Mostly sunny skies are in the forecast for southern Utah through the middle of next week, with temperatures rising from the mid-50s to the upper 50s through the beginning of the work week. However, after a high of 58 on Monday, the cold front will drop St. George to a high of 49 on Tuesday and 45 on Wednesday. Overnight lows will be in the upper 20s and low 30s.
