Salt Lake City is starting today clear, dry, and already around 81°F at the airport, with humidity near 20%. The valley is headed for a high near 101°F, and the heat will arrive alongside patchy smoke and a serious warning for heat-related illness.
Extreme Heat Warning Runs Through Sunday Evening
The National Weather Service has an Extreme Heat Warning in effect for the Salt Lake Valley through 9 p.m. tonight, with temperatures expected to reach about 101°F and little relief overnight, according to NWS Salt Lake City. Residents should drink plenty of fluids, use air conditioning or shaded spaces, and avoid leaving children or pets in parked vehicles.
South winds near 25 mph were being reported at Salt Lake City International Airport early Sunday, although the daytime forecast calls for lighter winds around 5 to 7 mph. Mostly sunny skies will not offer much protection from the heat, with temperatures climbing through the 90s during the afternoon.
Smoke And Dry Winds Add A Fire Risk
Patchy smoke is expected to linger across the valley, potentially leaving skies hazy and reducing visibility in spots. The National Weather Service also says a dry cold front will move through late Sunday into Monday, bringing stronger winds and critical fire-weather conditions across much of Utah, as outlined in its forecast discussion.
That combination means extra caution with anything that could spark a fire, including outdoor equipment, vehicles parked in dry grass and recreational flames. The latest setup adds a new wind-and-fire concern to a summer that has already delivered repeated heat alerts across the region.
Monday Brings A Break Before Heat Rebounds
Monday will be noticeably cooler, with sunny skies and a high near 92°F before temperatures dip to around 67°F Monday night. Tuesday should reach about 93°F, followed by a warmer Wednesday near 97°F.
The heat returns to triple-digit territory Thursday, when the forecast calls for a high near 100°F, followed by about 102°F Friday and 101°F Saturday. The outlook stays mostly sunny and dry, with no meaningful rain expected through the weekend.
Plan Outdoor Time Around The Heat
People working or exercising outside should shift strenuous activity to the early morning or evening, take frequent breaks, and wear lightweight clothing. Anyone showing signs of heat exhaustion should be moved to a cool place immediately, confusion, fainting or hot, dry skin can signal heat stroke and require a 911 call.
