If the last weekend of August foreshadows summer's end, Utah's hottest season will go out with surge of sunshine, punctuated by thunderclaps and the scattered tears of rain.

Along the Wasatch Front, highs on Saturday will flirt with 90 degrees, up a few ticks on the thermometer from Friday. Afternoon thunderstorms and showers also are possible, ushering in overnight lows in the upper-50s. Sunday will dawn sunny and clear, ambling toward high temperatures in the upper-80s.

"August has passed, and yet summer continues by force to grow days," wrote novelist Jonathan Safran Foer. "They sprout secretly between the chapters of the year, covertly included between its pages."

Not so covert is the forecast for southern Utah, where Friday and Saturday will mix cycles of thunderstorms, showers and winds of 10-20 mph with bursts of sun rays and highs around 90 degrees. Sunday will bring clearer skies and thus hotter temperatures in the mid-90s.

Salt Lake, Utah, Washington and Carbon counties get the equivalent of the Utah Division of Air Quality's "tsk tsk!" with "yellow," or compromised levels of particulate pollution through the weekend, but the remainder of the state gets "green," or healthy grades.

Those assessments may only generate an unamused "Meh," and a sneeze or three from allergy suffers, however. The Intermountain Allergy & Asthma website reported that chenopods and sagebrush were at "very high" levels on its pollen index as of Friday, while mold was "high" and ragweed and grass "moderate."
