Air Quality Forecast

November 20 – November 24: A low-pressure system impacting the region has brought precipitation Thursday morning.  The bulk of the rainfall will be in the morning hours; however, expect diminishing scattered showers as the afternoon progresses.  As the weekend begins, the Central Coast should experience a slight warm up to seasonal temperatures and a drying trend as high-pressure builds behind the cold front.  The drying trend should last at least until the end of next week, so expect a pleasant Thanksgiving. Temperatures will range from the mid-40s to the low-60s at the coast and low-40s to the high-60s inland. Ozone levels should remain below State standards; therefore, ozone AQIs will remain GOOD. Moist conditions this week will keep PM10 (dust) AQIs in the Salinas Valley at GOOD as well. As conditions stabilize, expect a deterioration in ventilation.  This could bring PM2.5 AQI (smoke) levels to MODERATE, especially in the districts Smoke Sensitive Areas (SLV and Carmel Valley).
