High pressure continues to dominate the Southwest. Extreme Heat Warnings (in pink) still remain in place for cities including Phoenix, Tucson, Yuma, and the Coachella Valley. Heat Advisories (in orange) also remain in place through tonight across the California Coast including Los Angeles and San Diego.
Most of the Southwest, which is normally hot, will have many cities running above average and breaking records through tonight.
By tomorrow, we will start to feel the impacts of the trough that is digging into the PNW and the cooler air associated with it. Los Angeles will see temperatures drop down to the mid to low 80s by midweek.
