Salt Lake City is starting Wednesday under mostly cloudy skies and temperatures around 75°F, but the bigger story is waiting for the afternoon: another round of showers and thunderstorms could move across the valley. Highs should reach near 89°F, with storm chances rising after midday and lingering into early evening.

Storm Chances Build Wednesday Afternoon

The forecast calls for generally light winds that may shift during the day, along with about a 40% chance of showers and thunderstorms. Any storm that forms could bring a quick downpour, lightning, and sudden, erratic wind — enough to complicate an outdoor plan or briefly slow the commute, even if most of the city stays dry.

Thursday Brings The Wettest Stretch

The forecast takes a sharper turn Thursday, when showers and thunderstorms are expected for much of the day. The high should fall to about 82°F, rain chances climb to 90%, and new rainfall of roughly a tenth to a quarter inch is possible; storms remain likely Thursday night, with a low near 59°F.

The broader Utah forecast carries a marginal excessive-rainfall risk through Friday, with flash-flood potential becoming more widespread Thursday and Friday, according to the National Weather Service. No watches or warnings are currently posted for Utah, but drivers should be ready for slick roads, reduced visibility, and lightning if stronger cells move through.

Sun Returns For The Weekend

Friday stays unsettled, with a 50% chance of rain showers and thunderstorms and a high near 82°F. Conditions then dry out: Saturday should be mostly sunny near 85°F, Sunday mostly sunny near 88°F, and Monday partly sunny near 91°F.
