High heat and flash flood concerns remain over the Beehive State

SALT LAKE CITY ( ABC4 ) — Happy Monday, Utah! There will be above-normal temperatures across the state as high pressure remains overhead. However, monsoon moisture moving through the ridge will keep flash flood potential elevated through midweek.

After setting a record of 101° in Salt Lake City Sunday, temperatures remain well above average for today. Daytime highs will run 5-10° above normal for much of the region with upper 90s for the Wasatch Front. A high of 106° is expected for St. George.

Heat alerts have been issued for northern Utah once again through Tuesday evening due to excessive heat for the Wasatch Front. Moisture hangs on for the southern half of the state today with isolated showers and thunderstorms expected.

Flash flood potential remains ‘Possible’ for Bryce Canyon NP, Canyonlands NP, San Rafael Swell, and Zion National Park. ‘Probable’ flash flood potential remains in place today for Capitol Reef NP, Glen Canyon, and Grand Staircase-Escalante. Heavy rains will likely lead to flash flooding in slot canyons, normal dry washes, and near-recent burn scars. Stick to higher ground or be sure to know how to get to higher ground, if recreating in any of these areas today.

Little change to the forecast on Tuesday with above-normal temperatures continuing and the threat of storms in southern Utah.  Flash flooding remains possible in many recreational areas Tuesday afternoon with Bryce Canyon, Zion, San Rafael Swell, Capitol Reef, Lake Powell,  and Grand Staircase all having possible thunderstorms in the mix.

Temperatures should top out along the Wasatch Front in the upper 90s for many locations with Salt Lake City expected to hit 100°. Monsoon moisture will increase on Wednesday as a moist southwest flow will be in place. The added moisture, coupled with an approaching low-pressure system from the northwest, will bring a good chance of isolated thunderstorms to all of Utah on Wednesday.

The trough will pass to the north of the state on Thursday, keeping the threat of thunderstorms in place for the state. Flash flooding will likely remain a concern for the region as ample moisture will be in place. Temperatures will cool off across northern Utah behind the passing through Friday with dry weather settling back in.

The coolest temperatures will be felt across the state on Friday as daytime highs will be near seasonal average for many locations. This equates to mid-80s for the Wasatch Front and low 100s for St. George.

The relief from the high heat up north will be short-lived, however, as high pressure building back in for the weekend will allow temperatures to soar back into the mid to upper 90s along northern Utah. Southern Utah will continue to see triple-digit heat for the next 7 days with no real break in sight. Summer is here!
