Record highs will fall as an intense March warm-up kicks in later this week. Right now, we're forecasting a record-setting 86° Thursday, 90° Saturday, 91° Sunday, 93° Monday, 95° Tuesday (St. Patrick's Day), and beyond. The numbers for the rest of next week may be more than 20° above-average, which is very rare for any time of year.
Spring begins at 7:46 a.m. on Friday, March 20th.
The UV index is "high" from 11 a.m. through noon, meaning a sunburn could happen in 30 minutes for some people, so grab a hat and sunscreen if you're outside from mid-morning to mid-afternoon (9 a.m. to 3 p.m.).
The air quality forecast is "moderate" due to particle pollution, which tends to accumulate when we have light winds, cool nights, and mild days.
The forecast pollen levels have climbed to the "high" category and will remain elevated for the next month as trees continue to bloom across the valley. Ash, juniper, and elm are the predominant pollen types. Showering and changing after you've been outdoors, and keeping windows closed (especially when it's windy) is advised. Dust and dander aggravate allergies, but vacuuming and dusting often will help.
