After weeks of above-normal temperatures, it’s going to be a bit cooler than usual this week across much of Utah. And it’s going to rain, according to the National Weather Service — after one more day of heat and smoke on Monday, that is.
Temperatures in the low 90s are expected on Monday in Salt Lake City, and patchy smoke from fires in other states will continue.
Good morning! We're keeping a close eye on the remnants of Tropical Storm Kay off the California coast. Moisture from the system will move into S UT today before the remnants move across UT tonight through Tuesday, bringing the potential for heavy rain across the state. #utwx pic.twitter.com/ID9sDeBRWv

According to the National Weather Service, the remnants of Tropical Storm Kay will move into southern Utah on Monday and then move north throughout the state on Monday night and Tuesday, with the “potential for heavy rain across the state” through Thursday. Many areas will see a total of between a half an inch and an inch of precipitation.
In Salt Lake City, there’s a 30% chance of rain Monday night, rising to 80% on Tuesday; 70-80% on Wednesday; and 70% on Thursday before clearing on Friday.
The forecast high temperatures are 81 on Tuesday; 77 on Wednesday; 75 on Thursday; and 77 on Friday. Normal temperatures for this week in the Salt Lake area are 81-82.
The rain is expected to improve air quality. According to the Utah Department of Environmental Quality, conditions will be orange/unhealthy for sensitive sensitive groups on Monday in Salt Lake, Cache, Davis, Tooele, Utah and Weber/Box Elder counties, improving to yellow/moderate in all those counties on Tuesday. The forecast calls for it to remain yellow in Salt Lake, Davis and Utah counties on Wednesday, when it will improve to green/good in the other counties.
Scattered showers and thunderstorms are also expected in southern Utah. In St. George, there’s a 40-60% chance of rain on Monday; a 70% chance on Tuesday; and a 40-50% chance on Wednesday before sunny skies return on Thursday and Friday.
And temperatures, which are normally 93-94 at this time of year, will be somewhat cooler than that — 90 on Monday; 84 on Tuesday; 86 on Wednesday; 88 on Thursday; and 91 on Friday.
The arrival of the rain will mean a significant increase in the probability of flash flooding in Utah’s national parks, monuments and recreation areas. According to the National Weather Service, on Monday flash floods are probable in Grand Staircase-Escalante and Zion; possible in Bryce Canyon, Capitol Reef, Glen Canyon, Natural Bridges, and Grand Gulch, and not expected in Arches and Canyonlands.
On Tuesday, flash floods are probable in all 10 areas.
The threat of flooding will continue through Thursday, and the greatest danger will be slot canyons, normally dry washes and areas with recent burn scar
