As Southern Californians gear up for the weekend, the National Weather Service in San Diego predicts a slight temperature surge for the region. Following their recent forecast, Friday's temps will linger around the average mark, with a subtle hike as Saturday rolls in. The real kicker comes on Sunday, where the Inland Empire and desert communities face a "Moderate HeatRisk," particularly areas like San Bernardino, which has a 60% chance of experiencing highs exceeding 100°F. Overnight lows might provide some solace, dipping to the mid-60s and around 80°F for the lower deserts, respectively, as per the National Weather Service.
While coastal areas can expect highs in the lower 70s on Sunday, those inland are preparing to endure "temperatures around 5 degrees above average near the coast to 10 degrees above average farther inland," as per the National Weather Service. On the other hand, with the marine layer stubbornly hovering near 2000 feet, lower inland valleys won't see night and morning coastal low clouds spreading as far, allowing the sun to assert its presence with greater intensity.
Looking forward to the early part of next week, the weather narrative changes as a low-pressure system moves through California on Monday, enhancing onshore flow and initiating a cooldown. This will carry over into Tuesday, where temperatures across the region will hover around 5 degrees above average, creating more bearable conditions than the scorching weekend forecast. Residents can anticipate a slight warming on Wednesday, followed by cooler temperatures come Thursday.
Aviation interests take note, according to the National Weather Service's Area Forecast Discussion, coastal and valley regions will grapple with low clouds and restricted visibility during the early hours, though "otherwise...SCT high clouds and unrestricted vis today and tonight." Mariners are also clear, with no hazardous conditions anticipated through to Tuesday.
