Thursday, moderate to gusty northwesterly winds will disperse pollutants in the Sacramento region as a surface ridge of high pressure strengthens across far northern California. As a result, particle levels will be high-Good. Friday, a building ridge of high pressure aloft will hinder atmospheric mixing. In addition, morning and evening temperature inversions will confine pollutants near the surface, while calm to light southerly to southeasterly winds will limit dispersion. However, low pollutant carryover will lead to low-Moderate particle levels. Saturday, upper-level high pressure over the state will continue to inhibit vertical mixing. Furthermore, a strong morning temperature inversion will trap pollutants near the ground, and calm morning and evening winds will hinder dispersion. These conditions will yield mid-Moderate particle levels.
