According to the latest updates from the National Weather Service San Diego, San Diego residents can expect a shift in weather patterns this week. Those living near the coast and within the valleys will experience a cooling trend over the next few days as a low-pressure system approaches inland. By Tuesday, coastal areas will see temperatures ranging from 62 to 69 degrees, while inland valleys are predicted to endure a slightly warmer 67 to 74 degrees, as reported by NWS San Diego.
It may comfort some that despite the dip in temperatures, the deserts are expected to maintain their current warmth, with only minor changes. Rising from the western horizon, high pressure aloft paired with the weak offshore flow is anticipated to significantly increase heat, particularly for inland areas, by Friday. This warmer trend is estimated to deliver high temperatures for inland valleys, catapulting as much as 10 to locally 15 degrees above average, "with high temperatures into mid-70s to mid-80s for the valleys," according to the Area Forecast Discussion from the National Weather Service.
Furthermore, night and morning coastal low clouds and fog are expected to roll back into the picture late tonight, signaling a resurgence as early as Tuesday and Wednesday. This fog, which is likely to obscure the clarity of morning drives for commuters until it clears later in the day, will possibly nestle up to the western valleys, as detailed in announcements by the National Weather Service. Regarding air travel, mostly clear skies today and tonight will give way to isolated low clouds and fog after 05Z. However, the impact on coastal airports is uncertain, with 200-500 feet MSL ceilings and visibility ranging from 0 to 5SM, as noted by the National Weather Service San Diego.
San Diego's seaside communities should be especially mindful, as astronomical high tides predicted to crest at around six feet could lead to minor tidal overflow in the lowest coastal locations today and Tuesday. The National Weather Service has issued a Beach Hazards Statement for the area. Boaters and beach-goers will be relieved to hear that no adverse marine conditions are expected through Friday, the details of which are available through the NWS San Diego marine forecast. For those planning their week, the 7-day forecast suggests abundant sunshine, with gradual clearing after morning fog and highs potentially reaching the mid-70s by the weekend, as indicated by the National Weather Service's detailed forecast for San Diego.
