Air Quality Forecast

December 26 – December 29: Following the severe holiday weather over the last 48-hours, the Central Coast will experience one final round of precipitation as the work week ends.  As the weekend progresses and next week begins, high pressure building over the Pacific will move to the region bringing clear skies and a switch to northly winds, indicating a drop in temperatures.  Stable conditions should last until the end of next week where we see the potential for additional moisture. Temperatures will range from the low-40s to the low-60s at the coast and high-30s to the low-60s inland. Ozone levels should remain below State standards, therefore ozone AQIs will remain GOOD.  Moist conditions will keep PM10 (dust) AQIs in the Salinas Valley at GOOD as well. As high pressure builds and begins influencing conditions on the Central Coast, colder conditions will promote woodstove usage in the SLV which, in conjunction with a reduction in ventilation, could bring PM2.5 (smoke) AQIs into the MODERATE-UNHEALTHY FOR SENSITIVE GROUPS range.
