Air Quality Forecast and Weather Discussion
Friday, surface high pressure will briefly develop over northern California, with calm to light northwesterly winds limiting dispersion. Furthermore, cool temperatures in the evening hours will generate an inversion, trapping pollutants near the ground. However, low pollutant carryover from the previous day will yield low-Moderate particle levels. Saturday, a low pressure system will approach northern California, producing rain showers and enhancing mixing. However, light winds will hinder dispersion, keeping particle levels low-Moderate. Sunday, as the surface low remains over the region, strengthening southerly to southwesterly winds will disperse pollutants, leading to Good particle levels.
