Weather Conditions:
Wednesday, light to moderate northwesterly winds will effectively disperse pollutants in the Sacramento region, resulting in Good particle levels. Thursday, light to moderate southwesterly winds ahead of an approaching cold front will keep pollutants well dispersed in the Sacramento region, yielding continued Good particle levels. Friday, an upper-level trough of low pressure moving over northern California will enhance atmospheric mixing and produce moderate southerly winds in the Sacramento region, dispersing pollutants. Therefore, particle levels will remain Good.
