We'll turn partly-to-mostly cloudy Saturday and Sunday as southwest winds aloft carry in moisture for mid-and-high level clouds as a trough of low pressure approaches the West Coast. Weekend gusts range from 20-25 mph each afternoon.
Lows at night remain in the mid-to-upper 60s in Las Vegas through the weekend.
Las Vegas highs dip to the mid 80s Monday and the mid-to-upper 70s next Tuesday and beyond as low pressure covers the Western states for the first time in a couple weeks.
The UV index is "very high" from noon through 2 p.m., sun protection is advised between 10 a.m. and 5 p.m. A hat, light-colored clothing, and sunscreen are important when you're outside during that time. A sunburn can happen in as few as 15 minutes when the sun is highest in the sky.
Forecast pollen levels are "extreme" this week. Across the valley, mulberry, ash, and juniper are the predominant pollen types. Showering and changing after you've been outdoors, keeping windows closed when it's windy, and vacuuming and dusting more often will help, in addition to taking allergy medication.
The air quality forecast is "moderate" this week due to ozone and particle pollution, which accumulates when we have warm days.
