The consistent rise in mercury across Southern California’s inland valleys, coastal mountain slopes, and deserts, which some residents have grown accustomed to, is taking a slight downturn over the weekend. According to recent reports from the National Weather Service in San Diego, Friday’s scorching high temperatures, which scorched the lower deserts to a toasty 104 degrees and baked the Apple and Lucerne Valleys in the mid-80s to mid-90s, will give way slightly over the weekend.
