Friday, October 4 and Saturday, October 5: A pair of weak upper-level disturbances will aid atmospheric mixing over the northern Sierras. In addition, light to moderate westerly winds will disperse pollutants each afternoon and bring clean air into the region, leading to Good AQI levels on both days. Sunday and Monday, southwesterly daytime winds will weaken, reducing dispersion. However, warm temperatures will continue to aid low-level mixing in Portola, resulting in Good AQI levels on both days. Tuesday and Wednesday, calm winds and mostly clear skies will allow temperature inversions to develop each morning and evening, confining pollutants near the surface. Therefore, despite warm temperatures aiding low-level mixing each afternoon, AQI levels will increase to high-Good on both days.
