Time to unpack the sweaters, Utah. Autumn's frosty nights have debuted and its daytime highs, for so many weeks above the norm for the season, finally are cooling, too.
Indeed, the National Weather Service issued a Freeze Watch for portions of northeastern Utah's Uinta Basin Tuesday night through early Wednesday morning. As overnight temperatures dip into the 20s, any garden crops left unharvested will succumb to the cold, forecasters warn.
Along the Wasatch Front, lows Wednesday will slide into the upper-30s while daytime highs will be in the upper-50s to low-60s, about the same as forecast for Tuesday. Wednesday night also will bring rain showers that will continue into Thursday, when high temperatures are to retreat further, to the low- to mid-50s.
Southern Utahns, too, will feel some of fall's nip. While Wednesday's highs will be in the low- to mid-70s for Utah's Dixie, overnight lows will tumble into the 40s and low-50s. Wednesday night also will bring rain to the redrocks, a trend extending into Thursday.
Statewide, air quality will be in the "green," or healthy zone through the midweek, according to the Utah Division of Air Quality.
The Intermountain Allergy and Asthma website listed only mold at "moderate" on its pollen index as of Tuesday.
