Highs range from 111 to 114 over the next seven days. Overnight lows remain in the upper 80s this week and this upcoming weekend.
The chance of a stray storm rises to 10% this weekend and 20% early next week as the pattern flips to a monsoon-favorable set-up. Increased humidity next week will keep highs closer to 105. The precipitation outlook for August 11-17 reflects the above-average rain chances.
Sun protection is advised between 9 a.m. and 5 p.m.; a hat, light-colored clothing, and sunscreen are important when you’re outside. The UV index is strong enough between 10 a.m. and 4 p.m. that a sunburn can happen in just 15 to 30 minutes. From noon to 2 p.m. a sunburn is possible in just 10 minutes!
Forecast pollen levels are “low” this week, with ragweed and chenopods listed as 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.
The air quality forecast is “moderate” today and tomorrow on account of ozone.
