Air Quality Forecast and Weather Discussion
Monday and Tuesday, smoke from the Camp Fire will continue to impact the Sacramento region. In addition, calm to light winds will limit mixing and dispersion, and overnight temperature inversions will trap pollutants near the ground. These conditions will lead to Unhealthy particle levels on both days. Wednesday, as a cold front moves into northern California, moderate south-southeasterly winds will develop in the afternoon, aiding smoke dispersion. However, these winds will also bring smoke from the San Joaquin Valley into the Sacramento region. As a result, particle levels will be Unhealthy for Sensitive Groups.
