As June turns to July, it is — not surprisingly — hot in Utah. And it’s going to stay that way. But, according to the National Weather Service, Independence Day won’t be unbearable. At least not in northern Utah.
And there’s a moderate chance of flash flooding in central and southern Utah on Wednesday and Thursday.
The forecast calls for highs in the low 90s on Wednesday, Thursday and Friday; the mid-90s on Saturday and Sunday; and 92 on the Fourth of July, one degree above normal.
There’s a slight chance of rain Thursday night, but other than that, there’s no precipitation in the forecast. The sun is expected to shine brightly on Fourth of July parades on Monday.
Also not surprisingly, it’s going to be hotter in southern Utah. St. George will see highs of 101-102 Wednesday through Sunday. It’ll cool off a bit on the Fourth of July, but only a bit — a high of 98 is expected.
Other than a slight chance of rain on Wednesday afternoon, there’s no precipitation in the forecast for St. George.
However, thunderstorms could develop across central and southern Utah, mainly east of Interstate 15, on Wednesday and Thursday afternoon and evening — and the storms could bring heavy rain. According to the National Weather Service, there’s a moderate chance of flash flooding, with the greatest danger in slot canyons, normally dry washes and near recent burn scars.
The forecast for Wednesday is that flash floods are possible in Arches, Bryce Canyon, Canyonlands, Natural Bridges and Grand Gulch, and probable in Capitol Reef, Glen Canyon, Grand Staircase-Escalante, San Rafael Swell and Zion.
The air quality will improve along the Wasatch Front on Wednesday. According to the Utah Division of Air Quality, Salt Lake, Utah, Davis, Weber/Box Elder, Cache, Carbon, Duchesne, Iron, Tooele, Uintah and Washington counties will be yellow/moderate on both Wednesday and Thursday.
