Air Quality Forecast

December 19 - December 23: Regional high-pressure has kept stable conditions persistent over the central coast as of late.  Mild temperatures and pleasant weather are expected through Thursday.  Beginning late Friday, a series of low-pressure systems from the north will impact the region bringing moisture which should last through early/mid next week. Preliminary cumulative rain totals are expected to be 1.5” for the whole event, however this may change depending on how far south the front swings. Coastal temperatures will range from the high-40’s to low-60’s, and inland temperatures from the low-40’s to low-70’s. AQIs will be generally GOOD, with some MODERATE AQIs in our Smoke Sensitive Areas (SLV and Carmel Valley) during the early morning. Cool temperatures will keep afternoon ozone levels below State standards and thus air quality for ozone will be GOOD. Moist conditions will keep AQIs for PM10 (dust) GOOD as well.
