San Diegans is seeking a reprieve from the recent scorcher and will find a modest consolation this weekend. Forecasts by the National Weather Service San Diego confirm that a slight cooling trend is expected, with temperatures poised to drop 3-7 degrees below the high marks set on Friday. Inland areas have been sweltering with highs 10-20 degrees above normal, but the weekend should bring temps down to a still toasty but slightly more manageable 5-10 degrees above the average.
The coastal regions, while not as intensely heated, were blanketed by dense morning fog that caused visibility issues. According to the same source, this trend will continue into Saturday, with the marine layer potentially causing dense fog on the coastal mesas. Visibility concerns prompted the issuance of a Dense Fog Advisory for San Diego and Orange County coastal areas through 9 AM PDT this morning, with unhampered views not expected to return until later in the afternoon.
Looking forward, the NWS San Diego's Area Forecast Discussion details that an upper-level trough will split and move inland across multiple regions, heralding a gradual cooling effect that will extend into next week. "The split flow pattern remains somewhat messy through the week, though no matter the outcome the weather looks to remain relatively benign," the discussion explains, suggesting the weather could be unpredictable but not alarming.
Breezy conditions are anticipated to accompany the cooldown, particularly in the mountains and deserts, with gusts below 35 mph in the afternoons. The marine layer, currently very shallow, is expected to deepen and might bring light precipitation to some areas late in the week. However, chances of this moisture materializing remain below 10%, and San Diegans should expect to see an ongoing cooling trend with those characteristically breezy onshore winds.
