Monsoonal moisture lingers, potential for gusty winds and hail in some parts

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 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 for most. 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. Areas around St. George will likely climb to around triple-digits Monday afternoon.

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 some small hail in some of these cells.

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 arrives Tuesday, 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 return on Wednesday when some may see a brief afternoon storm, but Thursday and Friday are when we expect the most thunderstorms.

A deep upper low that has been hanging out off the west coast, could make a track inland by this upcoming weekend! This could lead to drier weather arriving but even more, much cooler weather could surge into the region, leading to temps dropping significantly for the weekend. Stay tuned!
