Beginning Saturday, a cold front advancing on western Utah will maintain strong southerly winds across much of Utah. Numerous wind advisories and high wind warnings are in effect through Saturday evening. Isolated showers and thunderstorms ahead of the cold front will increase rapidly in both areal coverage and intensity as the front sweep east across the state. The strongest showers and thunderstorms will develop across west-central Utah Saturday morning, then move into northern Utah in the afternoon. Lowering snow levels will quickly turn rain to snow at the higher elevations this afternoon and through the overnight hours.

Cold and unsettled conditions will exist across the outlook area through Sunday. Accumulating snow will continue across the higher elevations through Sunday night. Significant snow accumulations on the higher valleys is not expected, though a dusting of snow is possible.

Cold and unsettled weather with showery precipitation will continue across the outlook Monday. High pressure aloft will return beginning Tuesday. The high pressure will produce a warming trend with dry conditions through the end of the week.

High Wind Warning

Affected area includes southwest Utah.


South to southeasterly winds are expected to become strong early Saturday morning and continue through the day with gusts in excess of 60 miles per hour. Winds will diminish late in the day and then drop off around 10 p.m. Saturday.


Strong cross winds will create hazardous driving conditions for high-profile vehicles across west to east oriented routes throughout the day. Reduced visibility is possible in blowing dust. Light weight loose items may become airborne and wind sensitive operations will be affected.

Precautionary/ preparedness actions

A high wind warning means a hazardous high wind event is expected or is occurring. Sustained wind speeds of at least 40 miles per hour or gusts of 58 miles per hour or more can lead to property damage. Vehicles, especially high-profile vehicles, can be difficult to control at times in high winds. Motorists should take extra caution, especially while crossing bridges, overpasses and unsheltered areas.
