Air Quality Forecast

June 25 – June 29: Low-pressure over the PNW will slowly migrate eastward through the Basin and Range and affect conditions for the Central Coast as we enter the weekend. The low will effectively cool things down and direct winds in an onshore pattern as gusts reach 30-50 mph in the Salinas Valley and other wind prone areas. As the low leaves on Sunday expect high-pressure to build again, bringing back a warming trend and seasonal temperatures next week. Temperatures will range from the low-50s to the high-70s at the coast and high-40s to low-90s inland. Cooler-seasonal temperatures will keep ozone production down; therefore, ozone AQIs will remain GOOD.  Decent wind speeds could bring PM10 AQIs to MODERATE however, moist conditions from extensive marine stratus should be able to limit this.  As low pressure remains, expect PM2.5 (smoke) AQIs to remain GOOD.  Building high-pressure next week will reduce ventilation and we could see MODERATE PM2.5 AQIs.
