AFTERNOON: A 10% chance of an isolated shower, otherwise partly cloudy with 20-30 mph gusts and highs in the low 70s.

Saturday morning remains breezy with 15-25 mph winds at sunrise and temperatures in the 50s. The rest of the day looks nice: enjoy less wind Saturday afternoon with a partly cloudy sky and highs in the upper 60s.
Sunday is partly cloudy and calm with readings near 50 at sunrise (40s away from The Strip) and afternoon numbers in the mid 60s.
There's a better opportunity for rain late Monday afternoon and Monday night through early Tuesday (chance in Las Vegas climbs from 30% to 60%). Highs drop from the mid 60s Monday to the low 60s Tuesday through the rest of the week. Tuesday turns breezy with southwest gusts of 20-25 mph as showers linger.
Tuesday night falls to the 40s in Las Vegas for the first time since April. Wednesday remains cool, in the low 60s, with a break in the moisture before another chance of showers works our way Thursday.
Thick clouds aside, sun protection is still advised between 10 a.m. and 2 p.m.; a hat, light-colored clothing, and sunscreen are important when you're outside. The UV index is high enough that a sunburn can happen in 30-45 minutes.
The air quality forecast has improved from moderate to good today and tomorrow as the forecast winds finally clear out the particle pollution.
Forecast pollen levels are "low" this week. Elm, chenopods, and sagebrush are the predominant pollen types. Showering and changing after you've been outdoors, keeping windows closed when it's windy, and vacuuming and dusting often will help battle symptoms, in addition to taking allergy medication.
