Air Quality Forecast and Weather Discussion
Wednesday, as a trough passes over northern California, gusty north-northwesterly winds at the surface will effectively disperse pollutants in the Sacramento region, yielding Good particle levels. Thursday and Friday, lighter winds will limit dispersion. Additionally, cold morning temperatures will produce a strong inversion, trapping pollutants near the ground. However, low pollutant carryover from day to day will yield low-Moderate particle levels on both days.
