As San Diegans anticipate fluctuations in the weather patterns, the National Weather Service San Diego has indicated a vibe of subtle relief with a gradual cooling trend through Sunday. Coastal residents can expect lingering clouds and slightly cooler temperatures, with highs in the upper 60s to mid-70s, while inland Orange County and San Diego County valleys will observe the mid-70s to lower 80s. According to a forecast by the National Weather Service San Diego, the Inland Empire is likely to experience a modest drop in temperature to the upper 70s and upper 80s.
The lower deserts, after searing highs that surpassed 110 degrees on Thursday, will see some margin of respite with temperatures mostly reaching 105 or less by Sunday. Moreover, a chilling down is on the cards for the Inland Empire, where temperatures are poised to sink below seasonal averages by 4 to 8 degrees, settling in the comfortable sweep of the mid-70s to mid-80s on Sunday. The forecast discussion from the National Weather Service suggests "There will be a slow cooling trend through the weekend" and advisories are in place with an Excessive Heat Warning until 9 PM PDT this evening for specific valleys and desert regions.
Despite the cooling, the marine influence remains stable as the marine layer jostles between 2000 and 2500 feet deep. The coastal clutch and inland valleys will be draped in morning mist, with potential drizzle adding a damp touch to the ambiance. Orange County witnessed a measurable 0.01 inch of precipitation overnight, wrapping the region in cool moisture.
Gusty southwest to west winds will pepper the late afternoons to evenings for the mountains and deserts. The northern Coachella Valley can buckle up for gusts hitting up to around 50 mph, for those venturing through the iconic San Gorgonio Pass. The marine conditions, however, appear benign with no hazardous conditions projected through Tuesday. As for sky enthusiasts, Skywarn activation is not anticipated but local weather spotters continue to play a key part, lending an eye to significant climatic shifts.
