San Diegans brace for sweltering temperatures as the National Weather Service forecasts a scorching weekend. According to NWS San Diego, today's weather marks the peak of a heat wave, with inland valleys hitting the upper 90s to 103 degrees and the Inland Empire soaring up to 110 degrees, while coastal areas maintain slightly milder mid to upper 70s. The heat is expected to intensify in the deserts, where temperatures could climb to a blistering 115 to 121 degrees.
The high-pressure system plastered over California isn't going anywhere soon. Per the Area Forecast Discussion from the NWS, high temperatures of 5 to 15 degrees above average will continue into next week, and areas below 6000 feet in the mountains are predicted to experience highs in the 90s to near 100 degrees. Health officials urge individuals to stay hydrated and limit outdoor exposure, especially considering the heat risk for inland areas, which remains high to extreme. This warning is crucial for residents and visitors to heed to prevent heat-related illnesses.
As temperatures tilt slightly cooler on Sunday west of the mountains, the excessive heat won't relent for the desert regions. A marine layer will bring some reprieve to coastal areas, where beachgoers can anticipate highs in the pleasant 70s, but those in inland valleys should prepare for another round of 90s and low 100s. Despite the oppressive heat, the marine forecast remains benign, with no hazardous conditions predicted through Tuesday. Beach hazards, however, are in effect due to elevated surf from a long-period south swell, with the National Weather Service advising caution, especially on south and southwest-facing beaches where surf could reach 6 to 7 feet in height.
Into the next week, there's potential for the high pressure to restrengthen, leading to another uptick in temperatures. Although the forecast remains less clear, the outcome could swing depending on the position of the high-pressure system. It could spur potential monsoon storms or further bake the region, according to discussions by meteorological experts. The National Weather Service indicates a slight signal for monsoonal moisture by next Thursday and Friday, an aspect that will be monitored as the weather pattern develops.
