A third wave of snow this week is expected to hit Thursday night and impact the Friday morning commute.

The National Weather Service said most of the state will see cold temperatures and precipitation from Thursday evening to Friday afternoon, though accumulations will be lighter than they were earlier in the week.

Mountains and valleys from the Wasatch Front to St. George and Kanab will see snow, according to the NWS, and travelers along Interstate 15, Interstate 70 and U.S. Highway 89 as far south as Kanab will likely face slick roads with reduced visibility. More details about where and when the snow will hit can be found on the Utah Department of Transportation‘s website.

A hazardous weather outlook issued by the NWS says that snow will reach higher altitude areas Thursday afternoon, central and southern Utah valleys in the evening and northern Utah valleys later in the night.

That snowfall is expected to taper off Friday afternoon.

There will be another chance for snow Saturday evening and then again early next week, the NWS said.

Highs in the Salt Lake and Tooele valleys will reach the mid-30s Thursday with mostly cloudy skies and winds blowing at about 10 to 20 mph in the afternoon. There is a 50 percent chance of snow overnight, as temperatures dip down to the mid-20s. On Friday, snow is likely in the morning with expected accumulation of about an inch. Highs will reach about 30 degrees.

In southern Utah’s St. George area, skies Thursday will be partly cloudy with highs in the upper 40s and winds blowing from 10 to 20 mph. Rain and snow is likely in the evening, with that likelihood increasing after midnight as lows drop to about 30 degrees. However, the area is not expected to see snow accumulation. On Friday, there will be a chance of snow in the morning and a rain-snow mix in the afternoon. Highs will reach the mid-40s.

The Utah Avalanche Center warned of considerable avalanche danger Thursday in areas near Logan, Ogden, Salt Lake, Provo, Skyline and Moab. Moderate danger exists near the Uintas and Abajo.

Air quality is good throughout the state, according to the Utah Division of Air Quality.
