As we settle into the tail end of August, Southern California locals can expect the weather pattern to hum along predictably, with coastal low clouds and gradual inland seepage marking the days ahead, National Weather Service San Diego reports. Today's highs are not far from yesterday's, with San Diego and Orange County coastal areas hovering in the lower to mid-70s, while inland valleys are looking to warm up to the lower 90s. The deserts are set to bake from 105 to 110 degrees.
Tomorrow promises a slight uptick in warmth, nudging inland valley temperatures into the mid-90s while deserts push the mercury up between 106 and 112 degrees. As moody as ever, the marine layer is fussing with depth and reach, stretching inland over valleys this morning and then sheepishly retracting next week, becoming patchier and clinging close to coastal skirts, according to the Area Forecast Discussion. This Friday, a whisper of monsoonal moisture flirts with the possibility of showers or thunderstorms for the Riverside and San Bernardino Mountains, though chances dangle low at less than 15 percent.
In the longer view, the forecast suggests a slow yet steady climb in temperatures into next week, particularly for the coast and valleys where an increase of 10 to 15 degrees may manifest. This bodes a potential swelter sufficient to trigger heat advisories or excessive heat warnings for some inland stretches by mid-week. The mountains and deserts stare down a lesser jump, expecting no more than a 5-degree rise from today through Thursday of the following week.
Marine traffic and outdoor aficionados can sigh relief as the National Weather Service San Diego forecast dispenses confidence in the continued absence of hazardous marine conditions through Monday. For those aloft in the skies today, aircraft operations can anticipate unrestricted visibility and mostly clear conditions above the mountains and deserts. On the maritime front, the marine layer's early morning dance with coastal low clouds will reprise itself after nightfall, moving in and out, an ever-changing panorama for the seafarer and land-dweller alike.
