Area Forecast Discussion National Weather Service San Diego CA 756 AM PST Thu Jan 23 2020

SYNOPSIS. High pressure over the West Coast will continue to build in through Saturday, bringing dry weather and a warming trend. A coastal eddy could bring low clouds and cooler temperatures to the coast on Saturday. A weak low pressure system will bring cooling Sunday and Monday. High pressure will build back in on Tuesday, bringing dry weather and a warming trend for next week.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

At 8 AM, weak offshore flow at the surface and aloft has kept marine layer clouds and fog far offshore. Some mountain and foothill locations are reporting breezy north winds with gusts of 25 to 35 mph. Winds will diminish later this morning.

High pressure near the West Coast will continue to build into southern California today through Saturday, resulting in dry weather and warmer temperatures. Daytime highs will run a couple of degrees warmer than normal along the coast, while in the valleys and mountains, highs will be 5 to 10 degrees above normal. Warmer weather will continue through Saturday, with little day to day temperature variation.

High resolution models are showing a coastal eddy developing Friday night and continuing through the weekend. This could bring cooling near the coast Saturday and the return of low clouds at times.

On Sunday, a weak Pacific trough will move inland and bring cooling to much of the region through Monday. Deterministic models and their ensemble solutions continue to trend weaker with this system, so precipitation chances are decreasing. Little if any precipitation is expected, but if any sprinkles do fall, it will be during the day on Sunday. Nevertheless, stronger onshore flow can be expected with gusts of 25 to 35 mph in the mountains and deserts on Sunday.

High pressure over the eastern Pacific will build into the region on Tuesday and strengthen throughout the week. This will result in dry weather, a warming trend, and a shallower marine layer through the end of next week.

AVIATION. 231545Z . Mostly clear skies and unrestricted VIS will prevail today and tonight. Very small chance in coastal sites seeing any low clouds tonight, however low clouds could develop along the immediate coast overnight.

MARINE. No hazardous marine conditions are expected through Monday.

BEACHES. Swell and elevated surf will gradually diminish today. A new long-period swell will arrive Saturday and continue through Sunday, bringing surf of 4-6 feet with higher sets possible, especially in southern San Diego County and northern Orange County. Strong rip currents are expected through the period.

SKYWARN. Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
