Dec 7 to Dec 12 The slightly wet weather from Tuesday morning is expected to be followed by more light rain Wednesday afternoon and into Thursday. Weather will be cool for a couple of days into the weekend followed by a low pressure system that is expected to move into the area and potential widespread rain early next week. AQI for PM10 and ozone are expected to be GOOD. AQI for PM2.5 is expected to be GOOD but may become MODERATE in the San Lorenzo Valley with the cooling trend. These unstable conditions for the next five days are expected to reduce the effects of potential inversion layers and reduce smoke buildup.
