The heat wave hitting Southern California this week is one for the record books. Temperatures topped 100 in the valleys and 120 in the low desert. Death Valley hit 127 — seven degrees shy of the hottest temperature ever recorded on the planet. The National Weather Service said temperatures in some low desert locations were “among the highest ever recorded.” The temperature hit 124 degrees on Tuesday in Ocotillo Wells — the highest reading ever recorded in San Diego County, according to the National Weather Service. Forecasters said the reading was two degrees above the previous high of 122, which was recorded in Borrego Springs on June 20, 2016.
