Thunderstorms remain possible in southwest Utah while all areas see baking heat

SALT LAKE CITY (ABC4) — Happy Monday, Utah! If you liked yesterday’s weather, you’re in luck because today’s forecast is pretty much the same.

High pressure to the southwest brings high heat and monsoonal thunderstorms to the Beehive State. Expect daytime highs to be about 5 degrees warmer than usual for this time of year.

Up along the Wasatch Front, temperatures will be flirting with the triple digits, ranging from the upper 90s to the low 100s. As you head south, it cools down a bit thanks to increasing cloud cover, with highs in the low 90s. However, places like St. George will stay hot, with temperatures around 106 degrees.

Southern Utah will see thunderstorms today, with some potential for flash flooding. Most of the moisture will hit south-central and southwest Utah, especially in higher terrain. Heavy rains in these high areas can cause flash floods in lower spots like slot canyons, dry washes, and creeks.

Flash flooding is a possibility in some of our outdoor recreation areas in southern Utah. Areas like Lake Powell, Bryce Canyon, Grand Staircase-Escalante, and the San Rafael Swell all have a “possible” risk for flash flooding. This concern for flash flooding will continue into tomorrow.

Northern Utah is likely to stay dry, apart from a brief afternoon shower along the Nevada/Utah border. Expect clear skies, although they might be a bit hazy due to smoke from wildfires in the northwest.

This smoke, combined with elevated ozone levels from the heat, will make air quality in the Wasatch Front “Unhealthy for Sensitive Groups,” with moderate air quality elsewhere.

High pressure is sticking around for the next few days, meaning we’ll see temperatures slowly rise. More cities will likely hit triple digits tomorrow and into midweek. Meanwhile, in southern Utah, monsoonal moisture and thunderstorms will keep temperatures more consistent.
