SALT LAKE CITY (ABC4) – We continue to roll on the atmospheric river remnants after this wet weather pummeled southern California.
After a brief break for some Tuesday morning, shower activity will be increasing in coverage across the state through the day with showers moving from north to south.
By Tuesday evening, just about everyone in Utah will have a good chance of finding some wet weather. Given our southerly flow, temperatures will once again trend above average with daytime highs ranging in the 40s and 50s for most outside of the high terrain.
Showers will come in the form of valley rain and mountain snow and given these unseasonably warm temperatures, snow levels could climb to or even briefly above 7,000 feet Tuesday afternoon.
Outside of any wet weather, skies will be partly sunny to mostly cloudy and it will be breezy to gusty across the state as well.
The statewide wet weather potential will remain high through Wednesday, but winds will begin to switch more westerly, then northwesterly. Cooler air will begin to filter in allowing snow levels to drop down below 6,000 feet to the benches by Wednesday.
Another storm looks set to move in from the northwest to round out the workweek and with the cooler air continuing to filter in, there’s a chance we could see valley rain and snow on Thursday while straight snow showers are possible in valleys by Friday.
Temperatures may even drop enough on Friday to see snowflakes mix in with rain in lower Washington County, albeit briefly! Moisture will try to linger into the weekend, but the overall trend looks to be drying out by late Saturday on what will be a chilly weekend with temperatures running slightly below average before we go on a steady warm up next week.
The chance for some upper 30s will feel a bit chilly with this latest stretch of above average 40s and even 50s in Salt Lake and the surrounding area.
Given our moisture potential, the National Weather Service already has alerts posted for the mountains for our next wave of moisture. Most of our alerts are currently in effect and in large part will continue through 5 a.m. Thursday except for the easternmost mountains which will continue through noon on Thursday.
There’s a winter weather advisory for the Wasatch Mountains north of I-80 while the Wasatch Mountains south of I-80, the Uinta’s, the central mountains, the Wasatch Plateau/Book Cliffs, the Tavaputs, the La Sal & Abajos, and the southern mountains are all included in Winter Storm Warnings.
When it comes to accumulations through Wednesday night, or the duration of the alerts, the Wasatch Mountains north of I-80 will likely see between 5-10 inches. The Wasatch Mountains south of I-80 will have potential to see 10-20 inches with 2 feet being possible for places like the Upper Cottonwoods.
The central mountains and western Uintas could receive 8-14 inches while the southern mountains could see 15-30 inches. Valleys will mainly see rain while benches could see either rain or a few inches of snow. Mountain valleys will likely land between 2-5 inches with up to 8 inches for typically colder mountain valleys given the high snow levels to start.
