The National Weather Service in San Diego has provided the latest weather outlook for the region, and it's looking like it will be a mild few days ahead for San Diegans. NWS San Diego forecasts that the coastal areas can expect temperatures between 71 to 77 degrees on Wednesday, with Thursday and Friday similarly cool. Moving inland, temperatures rise slightly with western valleys and Orange County hitting the 76 to 81 range on Wednesday and going as high as 89 in the inland valleys. It gets hotter in the deserts, with high deserts expecting up to 94 degrees and the low deserts climbing to 101 to 104 degrees today.
Within the week's broader context, temperatures stay below average until the weekend. According to a discussion by National Weather Service San Diego, "high temperatures for today will warm a few degrees for most areas to around 5 degrees for the valleys with high temperatures ranging from a few degrees below average to as much as 10 to 15 degrees below average for the mountains above 6000 feet." As we head towards Sunday, temperatures are expected to rise to around average, promising a warmer turn as the next week rolls in.
The marine layer, currently about 3000 feet deep, contributes to this cooling trend. It is bringing night and morning coastal low clouds, which have been extending into the valleys. However, the marine layer is anticipated to become "a little shallower for Thursday and Friday with night and morning coastal low clouds not spreading as far into the valleys late each night," as the NWS San Diego area forecast discussion details. Those living on or traveling through the desert slopes and into the deserts can expect regular afternoon and evening sea breezes, with some gusts potentially reaching up to 45 mph below the San Gorgonio Pass.
In aviation news, conditions remain generally favorable, although low clouds impact visibility, primarily where they intersect with higher terrain. The low clouds should retreat somewhat inland by mid-morning and from the coasts by late morning. "Coast/Valleys...Low clouds have continued to spread inland over the last several hours and now largely cover the entire coastal basin at this hour," according to the latest aviation report from NWS San Diego.
