As the weekend rolls in, San Diego's weather seems to be taking a slight turn towards the cooler side. A report from NWS San Diego indicates that high temperatures are set to be near seasonal averages before a gradual cooling trend sets in early next week. Today's warmth will dip into more moderate climes, and if you're wondering about rain, there's just a modest chance for showers and storms over the mountains today - less than 20%.
But we're not expecting just a brief cool-down. The Area Forecast Discussion by the National Weather Service San Diego echoes similar sentiments, pointing out that the monsoonal moisture is slowly retreating. While inland valleys might feel slightly above normal temperatures, coastal areas will experience temperatures near or just below the usual range. The balance makes deciding whether to wear shorts or pants a bit of a morning puzzle.
Starting Monday, an approaching low-pressure system means the mercury will drop a few more degrees. This system trekking from the northwest promises to instigate a noticeable cooling trend, one that's expected to last through the middle of next week. Think 70s and 80s west of the mountains, a pleasant break from the relentless heat. And as for the wind? Anticipate it to pick up a bit in the mountains and deserts, where gusts could reach between 25 and 45 mph.
For now, pilots and coastal commuters should take heed of potential low visibility as marine layer clouds stretch up to 20 miles inland with patches of fog. "Expecting slightly lower bases and less inland extent," the National Weather Service warns, indicating a shift in cloud cover as the weekend progresses. By Sunday afternoon, any lingering chances for showers and thunderstorms will likely dissipate along with the trailing monsoonal moisture.
