After a scorching heat wave brought triple-digit temperatures to much of the state, monsoonal moisture is on its way, with the expectation that it will bring a break in the heat, according to the National Weather Service.
The weather pattern change will bring increased monsoonal moisture over the next few days, the weather service says, with increased scattered daytime showers and thunderstorms.
The moisture will likely peak across Utah by Tuesday into Wednesday, bringing an elevated risk of flash floods and locally heavy rainfall, the weather service said. This will also cause temperatures to drop 5 to 10 degrees by Wednesday. Drier air is expected to return next weekend.
On Sunday, flash flooding is “probable” in some slot canyons, dry washes and small streams in Arches, Bryce Canyon, Zion, Canyonlands and Capitol Reef national parks, San Rafael Swell, Glen Canyon National Recreation Area, Grand Staircase-Escalante National Monument, Natural Bridges National Monument and Grand Gulch, the weather service said.
