Forecast Discussion: Smoke from the King Fire burning in El Dorado County will increase particle (PM2.5) levels in the Sacramento region on Thursday. In addition, particle levels are expected to be higher on Friday due to northwesterly winds. Smoke impacts will be greatest in the foothills east of Sacramento during the overnight and morning hours. Thursday, an upper-level trough of low pressure will move over northern California, enhancing mixing and generating moderate onshore winds. These conditions will disperse pollutants. In addition, cloud cover, scattered showers, and cooler temperatures will limit ozone formation, keeping ozone levels Good. Friday, the upper-level trough will continue to enhance vertical mixing in the Sacramento region, and light to moderate northwesterly winds will help to disperse pollutants. However, mostly sunny skies and warmer temperatures will aid ozone formation, resulting in low-Moderate ozone levels. Saturday, winds will shift to southwesterly, bringing cleaner air into the Sacramento valley. However, mostly sunny skies and warm temperatures will continue to enhance ozone production, leading to low-Moderate ozone levels.
