Outlook
Monsoon moisture is on the move today with pop-up t-storms in central and southern Utah likely. Along the Wasatch Front we'll see a dry first half of the day with increasing clouds into the afternoon and evening with some t-storm chances. Isolated afternoon/evening t-storms are possible Saturday and Sunday both with cooler temps in the mid-90s. High pressure will eventually move out of monsoon position by middle of next week, so a gradual drying trend is expected by that time frame. - Matt Johnson, KSL Weather 8.21.26
