| Area Forecast Discussion National Weather Service San Diego CA 925pm PDT Wednesday Mar 29 2023 Synopsis A large area of low pressure will continue to move southward along the coast of California through Thursday, leading to cold temperatures, gusty winds and periods of rain and mountain snow. Friday into the weekend will feature warmer and drier weather with less wind. Another trough will deepen across the western part the country by Monday. This will lead to cooler and windy conditions for the region for early next week, along with chances for rain again next Monday. For Extreme Southwestern California Including Orange... San Diego...Western Riverside and Southwestern San Bernardino Counties This evening...The extensive band of mostly light rain/snow with some embedded showers has moved to the east. A few showers have developed in the colder air behind the frontal band and ahead of a second organized band containing more convective elements. The parent low is currently off the coast of Monterey and continues to move southeast. The upper level closed low will move inland just to our north and will continue to bring showers this evening. It will bring a band of organized convective elements which will move into Orange County just around midnight then traverse the region from northwest to southeast overnight. The band of convective cells will move to the east by about 9 am Thursday. In addition to the showers, there will be a chance for thunderstorms which will continue with less coverage into Thursday afternoon. As the colder air moves in overnight, snow levels will fall to 4500-5000 ft and wintry conditions will impact the mountains above 5000 ft. Thursday will be a relatively cold day with daytime high temperatures 10 to 15 degrees below seasonal averages. We can expect some warming on Friday under a transient high pressure ridge between the low moving off to the east and another (weaker) low/trough moving in from the west. For Saturday through Early Next Week In spite of the passage of an upper low/trough on Saturday, we can expect fair weather this weekend. Most areas will be only a few degrees below average with mostly sunny conditions. Confidence is growing that we could get another low/trough with breezy conditions and a chance for precipitation next Monday as model guidance begins to converge on a solution. Early April may feature a continued troughing pattern with cooler than normal weather. Marine A storm will bring rain bands and gusty winds through Thursday. West winds around 20 kt with gusts 25 kt late tonight through Thursday, along with combined seas to 9 ft and steep waves. Isolated thunderstorms are also possible late tonight and Thursday morning, and these could produce waterspouts. Beaches There is a slight chance of thunderstorms tonight and Thursday at the beaches with cloud-to-ground lightning possible. Thunderstorms will be isolated if they occur.
