Air Quality Forecast

January 15 – January 19: Thursday will see the warmest temperatures for the forecast period as a region of high pressure migrates through the area. As the high passes, expect a cooling trend that will last through the weekend and at least into mid-week next week. The cooling trend will be the result of a low-pressure system from the north migrating to the region, bringing a chance of precipitation sometime next week. Temperatures will range from the mid-40s to the low-70s at the coast and high-30s to the low-70s inland. Ozone levels should remain below State standards; therefore, ozone AQIs will remain GOOD. Recent moisture and low wind speeds will keep PM10 (dust) AQIs in the Salinas Valley at GOOD as well. As high pressure remains, stable atmospheric conditions will maintain the weak ventilation we’ve been experiencing and bring PM2.5 (smoke) AQIs into the MODERATE-UNHEALTHY FOR SENSITIVE GROUPS range. This is especially true for the San Lorenzo Valley where woodsmoke can exacerbate air quality.
