Friday: Wind advisory throughout much of the state, red flag warning until 9 p.m.

Utahns can expect to see high winds throughout much of the state on Friday afternoon. A wind advisory remains in effect until midnight. Wind gusts of 20 to 30 miles per hour are expected, with the potential for speeds up to 50 miles per hour.

Areas of concern include Utah County to Cedar City, with the highest wind speeds west of Interstate 15 in that area.

Winds of up to 50 miles per hour are expected at the Great Salt Lake and Utah Lake on Friday afternoon and evening, which will mean higher waves and difficult boating conditions, according to NWS Salt Lake City.

Red flag warning: Fire danger remains in the southern and eastern valleys of Utah, with higher danger in areas where humidity levels fall below 15% and wind speeds are highest. A "red flag warning" is issued by the National Weather Service in conjunction with state and federal land management agencies to alert people to an ongoing or expected critical fire weather pattern, according to NWS Salt Lake City.

A red flag warning asks citizens to take action and be particularly careful with any open flames, especially in the outdoors, and to be aware of fire danger from other sources.

Saturday to Sunday morning: Winds decrease as the cold front moves out of Utah

Lighter winds are expected Saturday, except for the Price and Castle Dale area where downslope winds will gust Saturday afternoon and evening. Colder air settles into northern Utah Friday evening, bringing rain to the valleys and lowering snow levels in the mountains Friday night through Saturday morning. A few lingering mountain showers are possible on Sunday. 2News forecasters predict up to 4 inches of snow will fall in and around Alta.

Expect wintry conditions if you are traveling north through Utah or into Wyoming on Saturday and Sunday.

Camping forecast: Temperatures and conditions in the northern mountains:

Expect snow and wind in the northern mountains on Friday night, with estimated low of 27 degrees.

Snow showers are likely Saturday, with temperatures in the mid-30s. Saturday night, expect partly cloudy conditions with overnight lows in the 20s.

Partly cloudy skies return Sunday, with highs in the mid-40s.

Sunday afternoon: Temperatures warm, expect "beautiful" weather into Monday

If you're planning a Memorial Day barbecue, Monday is the day to do it, as high pressure begins to build across the state. Temperatures are expected to warm considerably on Monday and throughout the next week.

To prevent outdoor fires, the Utah Department of Public Safety cautions that fire pits, personal fireplaces, torches, and grills should be at least 10 feet from your home or anything that can burn.
