Air Quality Forecast

January 29 – February 2: A ridging pattern through Saturday will result in a warming trend for the region.  Beginning on Sunday, low pressure will bring a slight chance of rain, on the order of 10%.  So, if you are expecting some impactful rain event, do not hold your breath. By the end of Monday, the low should evacuate the region, and high-pressure will resume and last more than likely through the end of the work week. Temperatures will range from the mid-40s to the low-70s at the coast and high-30s to the mid-70s inland. Ozone levels should remain below State standards; therefore, ozone AQIs will remain GOOD. Low wind speeds should keep PM10 (dust) AQIs in the Salinas Valley at GOOD as well. As low-pressure enters the region, decent ventilation should help clear out any PM2.5 (smoke). However, as conditions stabilize, AQIs could reach into the MODERATE-UNHEALTHY FOR SENSITIVE GROUPS range. This is especially true for the San Lorenzo Valley where woodsmoke can exacerbate air quality.
