Southern California residents are gearing up for a scorching weekend as temperatures are set to soar above average. The National Weather Service in San Diego issued an Excessive Heat Warning. The heat advisory spans from 10 AM Friday through 8 PM on Saturday, mainly targeting the low desert areas. This warning comes as a high-pressure system currently lies over the Southwest, making itself comfortable right over Arizona and bringing in the unwelcome rise in mercury levels.
According to the detailed forecast by the National Weather Service, coastal regions can expect highs in the upper 70s to low 80s. In comparison, inland valleys may experience a sweltering range from the upper 80s to the upper 90s. Extreme heat will primarily affect the lower deserts, as the mercury there is predicted to reach between 104 and 113 degrees. Accompanying the heat for those who dare to brave the low desert, an Excessive Heat Warning will linger, shifting the landscape into a baking oven of sorts through early next week.
Traveling afield, the high desert won't be spared, expecting highs today between 90 to 95 degrees and then climbing potentially up to 102 degrees on Saturday. Meanwhile, though cooler, the mountains at elevations from 4500 to 7000 feet will also wrestle with highs in the 80s. The Area Forecast Discussion emphasizes a patchy dense fog, mostly occurring at elevations between 800-1200 ft in the mornings, creating challenging conditions for early risers and commuters.
The shallow and seemingly meek marine layer will stand by, offering its modest cooling effects mainly to the coastal areas and western valleys. Mariners, however, can find solace in the fact that hazardous conditions are not projected through Tuesday, according to marine reports.
