Light snow will dust the valleys and line the mountain benches Wednesday night, possibly sticking around long enough to affect some travel Thursday morning.

Most likely, only roads in higher elevations and mountain passes will be affected, the National Weather Service said.

Snow is expected to accumulate from a “trace” to 2 inches in valleys, 1 to 3 inches on mountain benches, 6 to 10 inches in the northern mountains and 8 to 14 inches in the central mountains, the NWS said.

The entire state was issued a hazardous weather outlook Wednesday as precipitation was expected to increase in the afternoon for the western two-thirds of the state and continue through the night. Along with the snow, a cold front will move in, according to the NWS. Snow is expected to continue into Thursday afternoon, especially along the Interstate 15 corridor.

Lower temperatures and additional snowfall are expected early next week as well, the NWS said.

The eastern third of the state can expect some fog early in the day Wednesday and light precipitation in higher elevations. Snowfall will increase in the mountains Wednesday night, and winter storm warnings and advisories will be in effect from Wednesday evening to Friday morning.

“The next chance for any significant precipitations looks to be Monday morning,” the NWS said.
