Area Forecast Discussion National Weather Service San Diego CA 141pm PST Tuesday Dec 3 2024 Synopsis Cooler conditions are expected through Wednesday with a deeper marine layer. Low clouds are expected to reach into portions of the valleys tonight into Wednesday morning. The marine layer will become shallower for Thursday and Friday. Warmer and drier conditions with weak to locally moderate northeasterly winds are expected for Friday and Saturday. Dry conditions will continue into early next week, with the potential for additional rounds of Santa Ana winds. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties At 1pm visible satellite was showing areas of high clouds across the area with a patch of dense fog off the southern San Diego County coast. As the overall flow starts to trend more onshore this evening low clouds are expected to become more widespread in coverage with areas of fog moving further inland to coastal mesas and higher coastal terrain by Wednesday morning. Low clouds are expected to reach the western valleys, maybe locally to the edges of the Inland Empire. The marine layer will start to become shallower Wednesday night into Thursday with the return of weak offshore flow, keeping areas of low clouds and fog mostly confined to coastal areas. Areas of low clouds are expected again Thursday into very early Friday before breezy northeast winds develop. Highs on Wednesday are expected to be a few degrees cooler than today. Even with the slight cooling, temperatures away from the coast will remain above average. Warming is expected for Thursday through Saturday. High pressure will build aloft just off the US West Coast for Friday and Saturday with an area of low pressure aloft over Arizona and northern Mexico. Weak to locally moderate northeast winds are expected, along with warm and dry conditions. High temperatures Friday and Saturday will be 7 to 15 degrees above average. Peak wind gusts will likely be 35 to 45 mph on the coastal slopes of the mountains, mountain foothills, and locally into the eastern valleys. Early next week, an area of low pressure will dig south into northern United States, with a ridge of high pressure near the US West Coast. There is still a lot of uncertainty on where the low will end up. For Monday, about 50 percent of solutions have the low digging into the Great Basin, with 50 percent showing the low's position further east and digging into the Upper Midwest. The uncertainty continues for Tuesday, with about 55 percent of ensemble solutions showing the low digging into the Four Corners region with the other 45 percent showing the low further east over the Midwest. The ultimate placement of this low will determine how strong any Santa Ana winds that develop would be. The overall pattern will also have an impact on temperatures for early next week. If the ridge axis is centered more over the US West Coast, the forecast will trend warmer with cooler solutions more likely if the low digs south into the Great Basin/Four Corners and the ridge axis stays just offshore. Current forecast follows the NBM for early next week. Dry conditions look likely to prevail into early next week. Marine No hazardous marine weather conditions are expected through Sunday. Skywarn Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions. NOAA San Diego CA Office: Watches - Warnings - Advisories CA...None.
