Jan 27 to Feb 01 A high pressure ridge off the West Coast will continue to maintain clear skies until this weekend when there is a slight chance of rain on Sunday through the California Central Coast area as a small low-pressure system passes through. We may see more rain around the middle of next week. Daily temperatures are ranging from the low-30s at night to mid-50s during the day. AQI for PM2.5, PM10, and Ozone are all expected to remain GOOD during this time, although AQI for PM2.5 may reach MODERATE in the San Lorenzo Valley area.
