Forecast Discussion: Wednesday, light north-northwesterly winds will disperse pollutants through the morning hours. However, winds will weaken in the afternoon and evening, reducing pollutant dispersion in the Sacramento area. In addition, moisture associated with light rain, fog, and mist will enhance particle production. Because of these conditions, particle levels will be Moderate. Thursday, as a deep low pressure system gradually approaches from the west, light to moderate southeasterly winds will develop, transporting additional pollutants into the Sacramento region. As a result, particle levels will remain Moderate. Friday, southeasterly winds will continue to bring regional pollutants into the Sacramento area through the morning hours. However, winds will strengthen midday, increasing mixing and dispersing pollutants. Therefore, particle levels will be low-Moderate. |
