Salt Lake City woke up to clear skies and relatively mild air, with the airport sitting at about 81°F, but the cool start is on borrowed time. Temperatures are set to rocket into the upper 90s this afternoon, with the hottest stretch expected from roughly 1 p.m. to 6 p.m. If you can, shift outdoor workouts, yard work, and errands to the morning or later in the evening, because this early comfort will fade fast as heat builds through the week.
A slight chance of showers and thunderstorms creeps in after noon, although most of the day should stay dry with a high near 97°F. Any storms that do form will be high-based, with more wind than rain, and capable of kicking out strong outflow gusts. According to the National Weather Service, the chance of precipitation sits at about 20%, and outflow winds could gust 40–50 mph.
Afternoon Winds Pick Up
If a storm pops up, outflow winds can show up quickly and with little warning, easily toppling patio umbrellas and tossing around lighter debris. Drivers, cyclists, and anyone recreating near canyon mouths should be ready for sudden gusts and brief visibility drops from blowing dust. Secure loose outdoor items, and give unsecured scaffolding or temporary structures a wide berth during the afternoon and evening commute.
Heat Outlook Through The Weekend
High pressure is expected to strengthen later this week, pushing valley highs into the low 100s across much of the Wasatch Front and 104–110°F in lower-elevation southern Utah by the weekend. Overnight lows will stay on the mild side, which means limited relief after sunset and a higher risk of heat illness for outdoor workers and vulnerable residents. The National Weather Service notes that its HeatRisk product points to "Major" and locally "Extreme" heat risk across parts of the state this weekend.
Where To Cool Off
Salt Lake County is operating public Cool Zones at libraries, senior centers, and community facilities, with extended hours for anyone who needs a break from the heat. Check Salt Lake County for locations and hours; several sites, including the Weigand Center, are open daily. If you or a neighbor does not have air conditioning, consider heading to a Cool Zone or calling 211 for assistance.
Quick Tips
Drink plenty of water, keep heavy exertion to a minimum during peak afternoon heat, and check in on elderly or medically fragile neighbors. Employers with outdoor crews should plan for shade, water, and extra breaks. If you notice dizziness, confusion, or heavy sweating, treat it as a warning sign and seek medical attention right away.
