Discussion for November 25 to 30 – An upper level trough from the Gulf of Alaska remains over our area today giving us cold air and partly cloudy skies. These conditions should continue through the weekend as the trough lingers over the western states. Air quality will continue in the GOOD category of the Air Quality Index in most parts of our air basin as a result of the unstable air from the trough. Overnight temperatures in the San Lorenzo Valley (SLV) will likely dip below freezing causing a build-up of residential wood smoke and elevated PM2.5 concentrations. PM 2.5 is expected to remain MODERATE, but could rise into the UNHEALTHY FOR SENSITIVE GROUPS category at night. The PM 2.5 concentration is not expected to violate the federal air quality standard, however, due to the unstable atmospheric conditions.
