Today, surface high pressure west of the region will produce calm to light and variable winds throughout the day, limiting dispersion and allowing pollutants to accumulate in the Imperial Valley. Furthermore, an evening temperature inversion will trap pollutants near the ground. Therefore, despite low pollutant carryover from the prior day, AQI levels will be mid-Moderate. Tomorrow, a strong morning temperature inversion will confine pollutants at the surface. Additionally, light southerly to southeasterly winds through the morning and afternoon will transport regional pollutants into the Imperial Valley. Although winds will shift to westerly by the evening, aiding dispersion, AQI levels will be high-Moderate.
