Forecast discussion for January 30 to February 4: No significant pattern change expected through the weekend as the unseasonably mild and dry conditions continue. Although a contorted upper level ridge briefly attempts to nose in from the Pacific, it quickly flattens out by Sunday allowing the recent spring-like progressive pattern to continue. Inconsequential increases in stability and PM2.5 levels may occur during this transition but not enough to support development of meaningful air stagnation. For most areas, AQIs for all pollutants are expected to remain in the GOOD air quality category. In the San Lorenzo Valley Smoke Sensitive Area (SLV SSA), mild overnight temperatures and light breezes should help to keep PM2.5 AQIs in the GOOD to MODERATE air quality category, with the higher values occurring where residential wood smoke is present. At this time, a Spare the Air Declaration for the SLV SSA is not being considered.
