As summer's afterglow gasps toward the fiery onset of autumnal color, Utah's midweek forecast is one for warm days and goosebump nights.

The Wasatch Front dawned clear and sunny Tuesday, heading toward temperatures in the upper-70s — the same highs predicted for Wednesday. Overnight lows will be in the low- to mid-50s.

The Irish poet W.B. Yeats knew about such days, suggesting we "pluck till time and times are done, the silver apples of the moon, the golden apples of the sun."

However, while the sunshine harvest was in place Tuesday and Wednesday, the waning crescent moon could disappear entirely behind storm clouds by late Wednesday night in the Salt Lake and Tooele valleys.

Rain showers were expected beginning early Thursday morning, culminating in windy afternoon thunderstorms.

Southern Utah's forecast called for partly cloudy skies and highs in the upper-80s Tuesday giving way to showers and thunderstorms Wednesday and Thursday, with temperatures retreating a few degrees. Overnight lows will be in the upper-50s.

Folks at the Utah Division of Air Quality smile at such weather. All that atmospheric stirring means fresh air, and that was reflected in the "green," or healthy grades awarded to all the state's monitoring stations through Wednesday.

However, stormy weather offers a mixed bag for allergy sufferers. The Intermountain Allergy & Asthma website reported Tuesday that sagebrush was "very high" and mold "high" on its pollen index.
