Widespread rain in the valley and snow in the mountains with rumbles of thunder on Friday


SALT LAKE CITY (ABC 4) – Happy Friday, Utah! A strong storm will move in and across Utah today bringing rain to the valley and snow to the mountains. Wet weather humidity becomes more prevalent throughout the day, and this afternoon precipitation can be heavy at times and there will be the potential for thunderstorms throughout the state.

Storms will develop in the afternoon and evening, and these thunderstorms not only bring thunder and lightning, but they also bring the potential for gusty winds, the risk of hail, and brief heavier rains. If you’re planning on being outside today, be sure to be aware of the weather!

While the valleys will face rain, snow across all of our mountains is likely, and our northern mountains will likely see the highest totals. A winter weather advisory has been issued for our northern Utah mountains that will run from 6 a.m. Friday through noon Saturday. Periods of heavy snow will be possible in the advisory where 8 to 16″ of snow can be expected.

Meanwhile, locally higher quantities will be possible, such as in the Cottonwoods. Snow combined with gusty winds will make winter travel tricky on mountain roads. Our southern mountains will also be included in a winter weather advisory that will run from Friday 9 a.m. to Saturday 1 a.m. Snow totals of 5 to 10 inches are likely in the southern mountains and, as in the northern mountains, isolated higher amounts will be possible.

It will also be another windy day across the state where we have several wind advisories in effect. A wind advisory from the San Rafael Swell to south-central Utah will run from 9 a.m. this morning to 6 p.m. tonight, where winds can be up to 50 mph. This could lead to dangerous crosswinds, blowing dust and possible power outages. The advisory for the Western Uinta Basin runs from tonight until tomorrow morning.

This storm system ushers in much cooler temperatures with daytime highs dropping about 20 degrees from Thursday. Below average temperatures are expected to persist for several days, including the weekend. Scattered showers remain likely Saturday, but instead of being statewide like Friday, wet weather will favor the northern two-thirds of the state Saturday.

Most of this storm will be valley rain and mountain snow, but with cooler air in place early Saturday and late Saturday we may see snow levels falling on the banks along the Wasatch front, especially if we can get a lake effect going early Saturday. Any accumulation of more than a few inches will likely be limited to elevations at or above 6500 feet. Don’t be surprised if you catch a winter mix of rain and snow in some valleys.

By the end of the weekend our weather will calm down as another pattern shift appears to be looming as a ridge of high pressure sets in leading to dry conditions and warming temperatures at the start of the next week.

At the end of the line ? It will be an active and cooler day across the state with soggy conditions in the mountains and valleys, so keep an eye out for the weather!
