Today, a morning temperature inversion will confine pollutants near the surface. In addition, light and variable winds will hinder dispersion, while sunny skies and high temperatures near 102F promote ozone development. As a result, AQI levels will be low-Moderate. Tomorrow, a weak trough of low pressure aloft will support atmospheric mixing. However, light southerly to easterly winds will limit dispersion and gradually transport regional pollutants into the Imperial Valley, while continued sunny and hot conditions aid ozone formation. Furthermore, isolated mountain thunderstorms could produce brief blowing dust during the late afternoon and evening. These conditions will result in another day of low-Moderate AQI levels.
