A gradual drying trend is on the meteorological menu for northern Utah heading into the weekend, along with temperatures once more rising well into the 90s.

The forecast for the Salt Lake and Tooele valleys calls for highs in the mid-90s both Friday and Saturday, after Thursdays isolated and weakening thunderstorms and showers ushered in  temperatures in the upper-80s.

However, triple-digit highs will rule southern Utah’s redrocks and high desert regions on Friday, mirroring Thursday’s hot, sunny forecast. Saturday, with the return of some storm clouds, will dip about 5-7 degrees into the low- to mid-90s.

Ozone and particulate pollution stubbornly maintain compromised air quality heading into the weekend. The Utah Division of Air Quality reported that only the rural counties of Carbon, Duchesne and Uintah merited “green,” or healthy grades on Thursday“ and they will join the rest of the state in the “yellow,” or moderate range for pollution on Friday.

Mold and chenopods were once again “high” on the Intermountain Allergy & Asthma websites pollen index, but other allergens ranked either low” or did not register as of Thursday.
