If you were enjoying the toasty Halloween weekend around San Diego County, the warmth isn't waving goodbye just yet. According to the National Weather Service San Diego office, today's desert to coast visitors can expect the mercury to climb 8-12 degrees above the seasonal norms inland, making for a warmer than usual welcome into November.
The current warmth can be attributed to upper-level ridging and some offshore flow, though gusts won't be ruffling too many feathers, topping at around 25 mph. Now, for those early risers or late-night wanderers, be prepared for patches of fog milling around the coast and far western valleys as the night proceeds into the morning. As for tomorrow, "minor cooling as onshore flow returns," the NWS in San Diego projects. This cooler trend will be nudged along by a trough of low pressure easing its way through the region as the week begins, so it's best to keep that light jacket handy.
The skies won't be entirely quiet, though. A weak cut-off low off the So Cal coast is anticipated to slide over the area come Sunday. It should mostly be making a guest appearance, showing off with scattered high clouds that "perhaps in time for some nice color during the one hour earlier sunset," according to the Area Forecast Discussion by NWS San Diego.
Through much of the week, we're looking at a relatively tranquil weather pattern. Two short waves to the north, previously touted to possibly bring some showers around mid-week, now seem less inclined to interrupt our dry spell. "Best we can possibly do is some marine layer drizzle Thu morning, but even that is looking less likely," the NWS San Diego adds. There's also talk of westerly winds picking up a bit across the high regions and deserts by Wednesday and Thursday, all the while the marine layer decides to delve a little deeper.
In aviation news, for those using the big blue overhead, coastal and western valley airports had to contend with low clouds and some visibility tapering down to just a few miles earlier today. However, air traffic should expect VFR (Visual Flight Rules) conditions to persist in the inland areas. As for the water-wise out there—sailors and beachgoers—the marine scene is thankfully sans any hazards through Wednesday. However, some sustained surf might send a few higher-than-average waves your way along southwest-facing beaches today through Sunday.
