Air Quality Forecast

 

July 25 – July 29: A troughing pattern appears to be developing over the region which should effectively cool things down through the weekend and into early next week by as much as ten degrees.  In the meantime, a HEAT ADVISORY is still in effect for Southern Salinas Valley/Arroyo Seco and Lake San Antonio; Santa Lucia Mountains and Los Padres National Forest; Mountains of San Benito County and Interior Monterey County including Pinnacles National Park, expiring Thursday at 11 PM.  Beginning mid-week next week, high-pressure will resume and we could be in for a slight warmup.  Stay tuned as model confidence increases and updates come in.  Expect temperatures ranging from the mid-50s to low-90s inland, and mid-50s to low-70s at the coast. With relatively cooler temperatures inland, AQIs for Ozone will likely be GOOD. AQIs for PM2.5 (smoke) will vary between GOOD and MODERATE due to smoky conditions state-wide. With calm winds, AQIs for PM10 (dust) will be GOOD.
