February 19-24, 2019 A high pressure trough will produce dry conditions with clear and sunny skies Monday through Wednesday. The next low pressure system will dip down into CA from Canada on Wednesday night bringing a chance of light showers for Thursday and Friday. Overall air quality is expected to be GOOD due to the rain events however, with the recent cooler nights PM 2.5 will continue to build up during the dry days this week. Wintertime thermal inversion will keep the smoke produced by wood burning heating devices close to the ground causing AQI in the basins, ravines and low lying areas, to increase especially the San Lorenzo Valley. Between storms, SLV and Santa Cruz AQI may increase into the MODERATE of PM 2.5. Ozone and PM10 levels are expected to remain in the GOOD range during this period.
