Jan 17 to Jan 22 The clear warm sunny weather we have enjoyed will end on Sunday. High winds expected Monday and Tuesday, which heralds a big change in the local weather conditions. Wednesday to Friday looks will bring cooler temperatures as the air flow shifts to a northwesterly direction, and some passing low pressure systems may bring in some rain over the weekend, possibly starting on Friday. AQI for both Ozone and PM10 are expected to be GOOD. The AQI for PM2.5 is expected to be GOOD in most areas except for the San Lorenzo Valley area where it is expected to be GOOD to MODERATE.
