Saturday, March 28 and Sunday, March 29: Calm morning winds will allow pollutants to accumulate in Portola each day. In addition, overnight temperature inversions will confine pollutants near the surface. However, moderate west-southwesterly winds will develop each afternoon, dispersing pollutants and leading to low-Moderate AQI levels on Saturday and high-Good AQI levels on Sunday. Monday, a passing weak cold front will gradually increase atmospheric mixing. Furthermore, strengthening southwesterly winds and scattered showers will disperse pollutants, allowing AQI levels to improve to Good. Tuesday, cooling temperatures aloft and occasional precipitation will enhance atmospheric mixing. In addition, moderate southwesterly winds will disperse pollutants during the afternoon and evening. As a result, AQI levels will be Good. Wednesday and Thursday, as a cold front approaches and moves through the Portola region, rain showers and gusty southwesterly to westerly winds will keep pollutants well dispersed, yielding Good AQI levels on both days.
