San Diegans can expect a mix of weather conditions in the coming days, with fluctuating temperatures and winds stirring up across the region. According to the National Weather Service San Diego, coastal and valley areas are seeing temperatures at or below normal today, while the high deserts are experiencing above-normal warmth.
Heading into Monday, weather patterns are set to shift, bringing more significant changes. "Weak northerly flow will bring warming for the coast and valleys and cooling inland," the National Weather Service notes. However, it's not just temperatures that are changing; winds are expected to "turn offshore and breezy for Monday," potentially impacting travel and outdoor activities, especially in mountain and desert regions, where peak gusts have been increasing in the afternoon.
The Area Forecast Discussion from the National Weather Service indicates that the cooling trend is a result of an upper-level trough digging southeast, deepening the marine layer, and even causing low clouds to reach inland valleys of San Diego County, while Orange County sees sparser coverage. This could lead to localized dense fog in areas where the clouds linger. Throughout today, expect brisk west winds in the mountains and deserts, peaking in the afternoon with gusts between 35-45 mph in wind-prone locales.
Monday brings a new dynamic, with weak to locally moderate Santa Ana winds developing, tapering off by Tuesday—this, as high pressure builds over the Great Basin. "Winds peak during the morning and early afternoon with gusts 30-45 mph below the passes, canyons, and foothills," bringing with it minor warming west of the mountains and cooling in other areas due to the influx of colder northern air, the weather discussion explains. Midweek predictions suggest fluctuating chances for light precipitation with only a "15-30% chance of showers Wednesday afternoon through Thursday morning" as current models indicate a decreasing likelihood of a more substantial weather system taking hold over Southern California, per the National Weather Service.
Mariners along the coast can breathe easy for now, as no hazardous marine conditions are forecasted through Friday. And for those sky watchers, or rather Skywarn spotters, the activation network is not currently in demand; however, significant weather conditions should still be reported if observed. As always, outdoor enthusiasts and commuters should stay tuned to the latest updates to ensure that the variable weather patterns don't catch them unprepared.
