The National Weather Service San Diego is forecasting a marginally warmer scenario for San Diego and the surrounding region this week, with gusty winds settling down by this afternoon. According to the NWS San Diego, mountainous areas and passes experienced the strongest winds, with some local spillover into the valleys earlier today. The high temperatures, still on the cooler side, are expected to creep up slightly from yesterday's mild chill.
Tomorrow promises a continued gentle rise in temperatures, with coastal and inland areas feeling a touch more heat, as stated on the NWS site. Weak northerly winds, which have characterized the Santa Ana conditions earlier, are to become easterly and diminish as the week progresses. The warming trend is largely attributed to a weaker offshore flow, which is expected to contribute to drier landscapes and clear skies through at least mid-week. Despite the tranquil weather that's settling in, a wind advisory was in place until 1 PM today for certain areas, including San Bernardino and Riverside Counties, cautioning against gusts reaching Wind Advisory criteria.
Looking ahead into the week, the region will experience a slow but steady warming, with inland areas expected to reach the 70s by Tuesday. According to an Area Forecast Discussion by the National Weather Service San Diego, "the weak offshore winds will also help to keep any development of the marine layer mostly confined over coastal waters," although some of this may creep onshore later in the afternoon.
As the week rolls into Thursday and Friday, however, there is an air of uncertainty as a potential low-pressure system looms on the horizon. This could either cool down the recently warmed temps with a return of onshore flow, or be thwarted by persistent high pressure and offshore flow, which would maintain the warmer, drier weather. Nevertheless, no hazardous marine conditions are anticipated through Thursday. As we edge towards the weekend, the marine layer remains indecisive, swayed with winds transitioning back to onshore flow by the end of the week, subtly nurturing the marine layer's presence in coastal late evenings and early mornings.
