San Diego residents can expect a dip in temperatures along with stronger winds through the end of this week, according to recent reports from the National Weather Service San Diego. NWS San Diego indicates a slow cooling trend that will bring temperatures below the seasonal average, with a notable increase in winds over the Mountains and Deserts until Thursday.
Indeed, the wind gusts in those areas are forecasted to reach 30 to 40 mph speeds, with even stronger gusts up to 60 mph in the northern Coachella Valley below the San Gorgonio Pass, primarily occurring today. As a large low-pressure system moves into the western states, this will not only cause stronger onshore flow but also deepen the marine layer to around 3000 feet, as stated by the Area Forecast Discussion from NWS San Diego.
Regarding temperature, Wednesday and Thursday's highs in the mountains, inland valleys, and high desert are predicted to be 10 to 15 degrees below average. Coastal areas will see lower 70s, while the Inland Empire can expect mid-70s to lower 80s, and the lower deserts might experience lower to mid-90s. Furthermore, coastal low clouds are expected to cover most of the coast and valleys during the early hours of Wednesday and Thursday.
Looking ahead to the weekend, a slight warm-up is on the horizon with temperatures nudging slightly below average near the coast to 5 to 10 degrees below average for the mountains and inland valleys. "There will be warming for Friday and Saturday with high temperatures ranging from a few degrees below average near the coat to 5 to 10 degrees below average for the mountains and inland valleys," reports the NWS San Diego. Saturday's highs could range from the lower 70s near the coast to the 80s for the Inland Empire and mid to upper 90s for the lower deserts. By Sunday and Monday, this warming may plateau, followed by further increases by mid-next week.
Maritime conditions will remain uneventful, except for northwest wind gusts of over 20 knots near San Clemente Island during the afternoons and evenings through Wednesday night. Skywarn, the volunteer program of weather spotters, has not been activated, but individuals are encouraged to report significant weather conditions as the week progresses.
