Utah's weekend forecast, in smoldering nutshell: hot and then hotter.

A few months from now, à la "chestnuts roasting on an open fire," a similar metaphor will evoke warm, fuzzy holiday feelings. But this is mid-August, and Jack Frost is nowhere to be seen — especially with temperatures soaring into the upper-90s along the Wasatch Front and well over 100 degrees in southern Utah in the coming days.

Gone will be the thunderstorms and cloud cover that gave northern Utahns some respite from the heat this past week. Instead, clear and sunny skies will prevail. In the Salt Lake and Tooele valleys, highs on Saturday will be in the low-90s — same as Friday's forecast — and the mercury will throb into the upper-90s by Sunday.

In Utah's Dixie the redrocks and high deserts will shimmer with even more severe, cloudless heat. The St. George area, forecast at 101 degrees Friday, will endure 103 on Saturday and 105 degrees on Sunday, the National Weather Services says.

Unless you are in Cache or Washington counties this weekend — they will be "green," or healthy, according to the Utah Division of Air Quality — particulate pollution levels will be in the "yellow," or moderate category.

The Intermountain Allergy & Asthma website reported that mold was at "high" and chenopods "moderate" levels as of Friday, but other allergens were either low, or did not show at all on the site's pollen index.
