Air Quality Forecast and Weather Discussion
Tuesday, sunny skies and temperatures warming to 90F will promote ozone formation. However, a light northwesterly breeze will disperse pollutants and continue transporting clean air into the Sacramento Valley, keeping ozone levels high-Good. Wednesday, a ridge of high pressure aloft will begin to reduce atmospheric mixing. In addition, high temperatures in the triple-digits will enhance ozone formation, leading to Moderate ozone levels. Thursday, northwesterly winds will decrease, allowing pollutants to accumulate over the Sacramento region. Furthermore, triple-digit heat and plentiful sunshine will aid ozone development, leading to high-Moderate ozone levels.
