ST. GEORGE — The National Weather Service in Salt Lake City has issued a hazardous weather warning for portions of central Utah, northern Utah, Southern Utah and southwest Wyoming, with the southern part of the state largely being impacted with winds and a cold front Wednesday and Thursday, and some minor snow around Cedar City Thursday through Saturday.

Affected areas

Cache Valley, northern Wasatch Front, Salt Lake and Tooele valleys, southern Wasatch Front, Great Salt Lake Desert and mountains, Wasatch Mountain valleys, Wasatch Mountains near Interstate-80 North, Wasatch Mountains south of I-80, western Uinta Mountains, Wasatch Plateau-Book Cliffs, Western Uinta Basin-Castle Country, San Rafael Swell, Sanpete-Sevier valleys, west-central Utah, southwest Utah, Utah’s Dixie and Zion National Park, south-central Utah, Glen Canyon Recreation Area-Lake Powell, central mountains, southern mountains and southwest Wyoming.

Day one — Wednesday

Showers expected primarily in areas along and north of Interstate 80. Gusty southerly winds are expected to impact mainly the southern portions of the outlook area ahead of a cold front Wednesday.

Days two through seven — Thursday through Tuesday

Winds are expected to increase Thursday across southeast Utah. Even stronger north winds are forecast for portions of western Utah Friday into Saturday behind the cold front. Valley rain and mountain snow will become more widespread across the north on Thursday with the cold front. Rain could mix with or change over to snow at times in the valleys as it spreads across more of the outlook area Thursday night and Friday.

Little in the way of travel impacts are expected in the valleys, although some minor accumulation will be possible at times. Colder valleys, including southwest Wyoming, the Wasatch crest and near Cedar City may have impacts at times late Thursday night into Saturday.

The northern and central mountains will see moderate snowfall with the cold frontal passage Thursday into the evening hours. Snow will likely become heavier from the southern mountains building northward late Thursday night into Saturday morning. This is the period when travel impacts will be most probable along all mountain routes.
