Salt Lake City gets one more run of blue-sky summer weather before the holiday weekend flips the script: Thursday starts clear around 61 degrees and climbs toward 87, while gusty south winds and very dry air build through the afternoon. The bigger change arrives Sunday, when showers and thunderstorms enter the forecast and linger into Labor Day.
Sunny Thursday Brings Dry, Gusty Air
Thursday stays sunny, with temperatures rising into the low 80s during the afternoon and south winds reaching 6 to 15 mph. The National Weather Service says humidity could fall into the teens later in the day, although no watches or warnings are listed for Salt Lake City in the current forecast.
The dry, windy setup matters more outside the city, where parts of western Utah could see locally critical fire-weather conditions. Gusts will remain a concern through the end of the workweek, so anyone heading into foothills or open space should be cautious with campfires, sparks, and loose outdoor items.
Friday And Saturday Stay Hot
Friday and Saturday look hot and mostly sunny, with highs near 87 both days. Friday brings south winds of 12 to 18 mph and gusts up to 32 mph, while Friday night could see gusts as high as 35 mph; Saturday should be somewhat calmer but still breezy.
Storm Chances Rise For Sunday And Labor Day
Sunday is the pivot, with a high near 82 and a 44% chance of showers and thunderstorms during the day. The chance rises to 51% Sunday night, followed by a cooler Labor Day with a high near 77 and a 50% chance of additional showers and thunderstorms.
The NWS Salt Lake City office says increasing moisture over the holiday weekend could produce locally heavy rain and flash flooding, particularly across central and southern Utah. That makes Sunday and Monday the days to keep outdoor plans flexible, especially near waterways, steep terrain, and areas prone to sudden runoff.
Quieter Weather Returns Tuesday
Tuesday rebounds to 79 degrees with mostly sunny skies and only a slight chance of showers and thunderstorms after noon. Wednesday reaches about 81 with another small afternoon storm chance, keeping the pattern warmer and drier than the holiday weekend but not entirely quiet.
