Utah forecast: Cooler temperatures to give way to hotter Friday

First Published      Last Updated May 29 2014 07:21 am

Northern Utah can expect a return of warmer temperatures on Friday in the wake of Thursday's cooler weather.

The National Weather Service credited a shallow cold front's stall across the state's mid-section Thursday for isolated thunderstorms and a 10-degree dip into the upper-70s along the Wasatch Front. On Friday, the mercury was to rise again into the upper-80s, cooled somewhat by afternoon breezes in the 10-20 mph range.

Southern Utah remained toasty under partly cloudy skies buffeted by winds of 15-25 mph as temperatures rose into mid-90s both Thursday and Friday.

Indeed, it was so hot and dry in the southwestern corner of the state that a "Red Flag" wildfire warning was in place for that region through 10 p.m. Thursday.

Southeastern Utah's Grand County was experiencing the heat in a different way: a Flood Advisory. Snowmelt was swelling the Colorado River and its tributaries, prompting the NWS to issue the alert, effective through 6 p.m. Thursday.

The Utah Division of Air Quality predicted "green," or healthy breathing conditions statewide on Friday, an improvement in particular for Weber, Washington and Duchesne counties from Thursday's "yellow," or compromised air quality ratings.

The Intermountain Allergy & Asthma website's pollen index was "very high" for grass and oak, "high" for maple and "moderate" for sycamore, mulberry and mold.
