After a few very warm days, a powerful cold front will swing into Utah during the day on Thursday. The front will bring high winds to areas of the state along with much colder temperatures and valley snowfall for the Wasatch Front, Northern Utah and portions of Central Utah.
Many locations statewide could see a 20 to 25 degree drop of daytime high temperatures by Thursday afternoon including St. George.
Rain will likely begin across Eastern Nevada and Northern Utah around midnight Wednesday as strong southerly winds keep temperatures warm, even in the higher elevations. Temperatures will drop rapidly with the passage of the cold front around the noon hour with any rain changing quickly to snow all the way to the valley floor. With temperatures much warmer this time of year, snow won’t stick to area roadways except over higher mountain passes. Some valley locations could pick up an inch or two with higher amounts on the benches and significant snowfall in the mountains.
Lake effect snow is possible Thursday night into Friday morning for the East benches of Salt Lake County and Cottonwood Canyons under a northwest flow. Winds look to shift to a more north northwest flow during the early morning hours Friday down the west side of the Salt Lake Valley which could lead to additional accumulations on grassy surfaces.
Cold temperatures and snow showers will linger into Friday across Northern Utah with clearing skies by the afternoon. We will take a break over the weekend as temperatures warm back up and winds increase ahead of more snow on Monday.
