Isolated mountain thunderstorms and rain showers not withstanding, northern Utah looked for slightly cooler and drier weather on Friday.
That forecast for the Wasatch Front was nearly identical to the National Weather Service’s menu for Thursday — mostly clear, sunny skies and high temperatures in the mid- to upper-90s.
Southern Utahns anticipated Friday evening thunderstorms after highs sizzling to 106 degrees, up 2 degrees from Thursday’s forecast.
The NWS had a Hazardous Weather Outlook in place through the weekend for the western two-thirds of the state as drier air spread into Utah from the Pacific Northwest. Forecasters warned that isolated heavy rainfall could trigger flash floods and mudslides.
The Utah Division of Air Quality graded Salt Lake, Davis, Weber, Utah, Cache, Box Elder, Duchesne and Washington counties as "moderate" or unhealthy for sensitive groups; Uintah earned a "good" air designation.
The Intermountain Allergy & Asthma website noted that only mold, at "high," and chenopods, at "moderate," showed elevated levels on its pollen index.
Salt Lake City’s high temperature for Friday was expected to hit 98, the same as Thursday; Ogden looked for 95 both days; Provo 97 and 96, respectively; Wendover 91 and 96; Duchesne 90s; Cedar City 90 and 94; St. George 104 and 106; and Moab 98 and 97 degrees.
