Forecast Discussion: Forecast discussion for December 17 to 22: Generally unsettled conditions continue through the work week as a conveyor belt of short-lived troughs and ridges move through the area. A pattern change to dry and stable conditions is then expected to set-in Saturday as a long-lived high pressure ridge builds in from the SW. This feature is expected to persist through Christmas. Overnight temperatures are expected to remain well above freezing as the offshore waters of the Pacific remain unusually mild, creating a moderating effect on temperatures. Air quality is expected to remain in the GOOD category over most of the region. However, in the San Lorenzo Valley overnight air stagnation can be expected to develop as the atmosphere stabilizes. Consequently, PM2.5 AQIs can be expected to crepe upward to the MODERATE to upper MODERATE categories with occasional excursions into the UNHEALTHY FOR SENSITIVE GROUPS category due to wood smoke from residential heating. The increase may be partially mitigated by the lack of exceptionally cold nighttime temperatures.
