SALT LAKE CITY – It may be spring, but at least one last dose of winter should arrive in Utah this week.
The National Weather Service released a winter storm watch for the mountains of northern Utah where a storm with the potential to deliver 1-2 feet of snow to start the work week. The storm is also expected to bring snow to the valleys.
“Enjoy (the weekend) because your shovels will most likely be needed,” said KSL meteorologist Kevin Eubank. “It’s kind of a big spring storm.”
A small cold front crossed on Saturday, mostly dropping high temperatures on the Wasatch Front by only 15 to 20 degrees. However, a trough system coming in from the Pacific Northwest on Monday is expected to be colder and add precipitation to the mix, Eubank said.
It is currently forecast to arrive Monday afternoon evening, providing rain in the valley and snow in the mountains for most of the state. But that changes overnight on Tuesday, as the rain turns to snow.
“Tuesday (it’s) all snow, all the way down the I-15 corridor, into eastern Utah,” he said. “Then a small secondary push occurs Tuesday afternoon and evening, and that pushes things along – even the lake effect snow continues into Wednesday morning.”
The winter storm watch comes into effect Monday afternoon and continues through Tuesday evening for the Wasatch and West Uinta mountain ranges. It includes communities like Alta, Brighton, Mantua, as well as places near the Mirror Lake Highway.
The alert says wind gusts of up to 40 mph are possible in addition to the possibility of 1 to 2 feet of snow.
Most valleys in the state are expected to receive snow accumulation. Eubank said 3 to 6 inches of snow is possible for the Wasatch Front Valleys, while the Banks can receive 6 to 10 inches of snow.
Temperatures will also drop again. High temperatures will reach the low 60s on Monday over the Wasatch front; however, they are only expected to peak in the 40s on Tuesday and Wednesday. Lows should fall below freezing.
High temperatures will return to the 50s to end the work week.
In St. George, highs will drop from the 70s to the upper 50s and low 60s on Tuesday and Wednesday before returning to near 70s by the end of the work week.
