Another day of near triple-digit temperatures was forecast for northern Utah on Friday, while southern Utahns looked for the mercury to surge above 100 degrees.
Those predictions, which mirrored forecasts for both regions on Thursday, did carry a slim hope for some relief from the heat: isolated thunderstorms and rain showers expected to roll over the state late Friday night.
Nonetheless, with continued hot and extremely dry weather expected, the National Weather Service had the northwestern quarter of the state — from the Utah-Idaho border south through the Wasatch Front and into the western deserts — under a Reg Flag Warning for wildfires through at least 9 p.m. Thursday.
Smoke and pollution-trapping heat also provided a mix bag for air quality. Salt Lake, Davis and Weber counties were rated at “Yellow,” or compromised; the rest of the state’s Utah Division of Air Quality monitoring stations for ozone and particulate pollution levels earned “Green,” or healthy breathability grades.
The Intermountain Allergy & Asthma website listed chenopods at “high” and mold at “moderate” on its pollen index.
Salt Lake City’s high temperature Friday was to be 100 degrees, the same as on Thursday; Ogden looked for 98 and 97 degrees, respectively; Provo 98 and 97; Logan 96 and 95; Wendover 97 and 96; Duchesne 89 and 87; Cedar City 90s; St. George 101 and 102; and Moab 98 and 97 degrees.
