SALT LAKE CITY (ABC4) – Happy Monday, Utah! Monsoonal moisture is lingering in the Beehive State today which means more thunderstorms, but not like what we saw over the weekend.

The bottom line? More severe weather and flash flooding on deck today. A brief break from wet weather is around the corner.

The monsoonal flow won’t be as prominent today as high pressure is starting to slide back westward toward us, cutting off the moist air flow. Most of the activity will be focused on the higher terrain, but isolated thunderstorms will still rumble across valleys around the I-15 corridor and the Great Salt Lake Desert in the late afternoon and evening hours. Apart from the isolated thunderstorms, it’ll be a mix of sun and clouds.

Temperatures will warm by a couple of degrees from yesterday which puts us right around average for this time of year. Daytime highs will be in the mid-80s to low 90s for most with upper 70s to low 80s in higher elevations. Salt Lake City and St. George won’t be too far apart temperature-wise with highs of 94 degrees and 98 degrees, respectively.

While the monsoon moisture is tapering off, there is still plenty of energy left in the atmosphere for severe thunderstorms and flash flooding. The Storm Prediction Center has most of northern and central Utah in a “marginal risk” which means some isolated thunderstorms could become severe. The biggest threat will be damaging winds, but we could see large hail in some of these cells as well.

Flash flooding will also be a threat to kick off the workweek for many of the outdoor recreation areas in the south. All of the national and state parks are in the “Possible” flash flood category, except for Grand Staircase/Escalante which is in the “Probable” zone.

If you plan on being in these areas, reschedule if possible. If not, make sure you stay weather-aware because flash floods can occur in places like slot canyons, dry washes, burn scars, and near streams with no warning – even if it isn’t raining where you are.

High pressure takes over tomorrow which will bring mostly sunny to clear skies for most of the state, but some mountainous regions could still have a shower or two roll through. The relief doesn’t last long, wet weather potential starts to slightly uptick on Wednesday when some may see a brief afternoon storm, but Thursday and Friday are when we expect the most thunderstorms.
