Salt Lake City rolled into Monday, July 20, under clear skies and a warm 79°F at daybreak, and that is about as cool as it is going to feel for a while. Afternoon highs are expected to push near 100°F, with overnight lows only dipping into the mid-70s. With just light winds on tap, the valley air will feel heavy and still as the heat builds. Scattered, hit-or-miss storms could pop up late in the day, but they are not expected to bring broad, lasting relief.
Heat Advisory In Effect
A Heat Advisory is in place from noon Monday, July 20, through midnight Monday night (12:00 a.m. MDT Tuesday, July 21) for the Salt Lake Valley and surrounding lowlands. The National Weather Service is warning about hazardous afternoon temperatures above 100°F paired with warm nights that never really cool down, a combination that raises the risk of heat-related illness. Officials are urging residents to dial back strenuous outdoor activity during the peak-heat hours.
Afternoon Storms And Short-Term Relief
Monsoonal moisture will keep the daily thunderstorm machine running through midweek. Storms are most likely to bubble up over higher terrain, then drift off into valley neighborhoods. For Monday night, there is only a slight chance for showers and thunderstorms in the valley. Coverage is expected to increase on Tuesday and Wednesday, when afternoon highs should come down a few degrees. Any storms that do fire could bring brief heavy downpours and gusty outflow winds that offer quick relief, then leave the heat to creep back in.
Where To Cool Off
Salt Lake County has opened Cool Zones and extended hours at several recreation centers for anyone who needs a dependable blast of air conditioning. The Weigand Center at 437 W 200 S is listed as open daily from 7 a.m. to 7 p.m., and the SLC Sports Complex at 645 S Guardsman Way is another option for staying cool. If you rely on air conditioning or cooling centers to stay safe, plan trips earlier in the morning or later in the evening to avoid the most punishing hours of the day.
Heat Safety Reminders
City officials and health experts are sticking with the basics for a reason. Drink plenty of water, steer clear of hard physical activity during the hottest part of the afternoon, and wear lightweight, light-colored clothing. Never leave children or pets in parked cars, even for a short stop. Check on older adults and neighbors who might struggle with the heat, and get immediate medical help for signs of heat stroke, such as confusion, fainting, or a lack of sweating.
Quick Look Ahead
Temperatures are expected to stay in the 90s with daily chances for afternoon thunderstorms through Wednesday, followed by a gradual drying trend later in the week. For the latest advisories, storm updates, and cooling-center details, keep an eye on the National Weather Service and Salt Lake County.
