Utah Weather Forecast

Outlook

Wildfire smoke will continue to vary in thickness at least through Thursday with highs in the mid to upper 90s along the Wasatch Front. Triple digits and near-record temperatures return to Friday and Saturday with forecast highs near 102 in SLC. St. George and most of southern Utah will be near 110 by the end of the week, which will also be near record territory. The reason for the climb in temperatures is due a high pressure system strengthening over the Four Corners region. Long range models are hinting at the return of a monsoon pattern as this high shifts slightly east through the week and early next week, driving moisture back into Utah from the south. As of now, isolated, mainly dry and gusty thunderstorms are possible in southwest Utah as early as Thursday, continuing daily through the weekend. If more moisture can move into the state Sunday or earlier next week, then storms will have a better chance at producing rainfall and potentially flash flooding. - Devan Masciulli, KSL Weather 8.4.26
