Developing thunderstorms and showers will usher in Utah's midweek, cooling the region after a long spell of near triple-digit and hotter weather.

But after Wednesday's and Thursday's Wasatch Front highs dip into the mid- to upper-70s — and upper-80s in southern Utah — the state ramps up for another hot weekend.

Take heart, though. Like this week's brief wet spell, summer heat, too, will eventually pass. William Faulkner once wrote of such times when, "The air was hot, vivid and breathless — a final fierce concentration of the doomed and dying summer."

But first, the treasure of relief. The National Weather Service forecast called for the storm clouds to begin building late Tuesday, then giving way to thunderclaps and precipitation — heavy in some locales — through Wednesday night.

Along with the break from the summer's heat will come atmospheric stirring that should clear out the smoke from wildfires in California, Oregon and Washington state.

Looking ahead to Wednesday and Thursday, the Utah Division of Air Quality rates all areas of the state as "green," or healthy, ending a spell of compromised, unhealthy air quality that had plagued Utah's valleys for the past week.

But you can't have everything. The Intermountain Allergy & Asthma website rated chenopods "very high," sagebrush, ragweed and grass as "high," and mold as "moderate" on its pollen index as of Tuesday.
