Southern California is bracing for another weekend of potentially dangerous temperatures. According to the National Weather Service San Diego, excessive Heat Warnings are in effect through Monday evening for several regions, including the Low Deserts, Inland Empire, San Diego Valleys, and the Santa Ana Mountains. Meanwhile, Heat Advisories are issued for the mountainous areas of San Diego, Riverside, and San Bernardino Counties.
Temperatures in coastal zones are climbing and are expected to consistently hover above average over the weekend. Forecasters predict that the coast and valleys will particularly feel the heat, with conditions rapidly becoming a few degrees warmer than those recorded on Thursday. Inland regions face temperatures around 12 to 18 degrees above average. However, This warming trend is projected to start cooling down next week, with Friday's high temperatures dipping slightly below average for coastal areas and remaining about 5 degrees above average for inland locales.
The weekend forecast indicates high temperatures near the coast will remain in the 70s, while inland valleys could experience sweltering highs between the upper 90s and 105 degrees. Detailed estimates by NWS San Diego also mention that the mountains and deserts will not see much change from the heat experienced on Thursday, maintaining elevated temperatures that pose health risks for residents and visitors alike.
The marine layer has deepened slightly compared to the previous 24 hours, resulting in better visibility along the coast. Over the weekend, this layer is set to become shallower with less inland spread, bringing only patchy night and morning coastal low clouds. Forecasters anticipate slight cooling to begin on Monday, with a more pronounced drop in temperatures throughout the region by the end of next week.
No hazardous marine conditions are expected through Tuesday, offering at least some reprieve for those seeking solace at sea from the inland heat. As the region faces these elevated temperatures, the Area Forecast Discussion issued by NWS San Diego encourages residents to stay informed and take necessary precautions to mitigate heat-related health risks.
