Area Forecast Discussion National Weather Service San Diego CA 257 AM PDT Tue May 26 2020

SYNOPSIS. High pressure aloft will continue well above average high temperatures for inland areas through Thursday with Wednesday and Thursday the hottest days for the deserts. The marine layer and weak onshore flow will keep coastal areas cooler with areas of night and morning low clouds and fog. For late Friday into Saturday, a low pressure system will move into California and strengthen the onshore flow. This will spread cooling inland with high temperatures returning to around average for the weekend. The marine layer will deepen with night and morning coastal low clouds and fog covering more of the valleys. A weak trough of low pressure will linger near the California Coast for early next week maintaining seasonal temperatures.

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

SHORT TERM (Today through Thursday). High pressure aloft over southern California will bring the hottest weather of the week for inland areas through Thursday with high temperatures 10 to 15 degrees above average. Wednesday and Thursday are expected to be the hottest days for the deserts. The marine layer will keep coastal areas cooler with high temperatures mostly in the 70s.

The marine layer and a weak coastal eddy during the late nights and mornings will continue the night and morning coastal low clouds and fog extending inland to the far western valleys. The weak coastal eddy should keep the marine layer just deep enough, around 1200 feet deep, for lowest visibilities to be in inland Orange County and the mesas and far western Valleys in San Diego County.

LONG TERM (Friday through Monday). A low pressure system to the southwest will move into northern and central California late Friday into Saturday. This will strengthen the onshore flow across southern California. This will spread cooling inland with high temperatures returning to around average for the weekend. The stronger onshore flow will bring stronger and gusty southwest to west winds in the mountains and deserts. The marine layer will deepen with areas of night and morning coastal low clouds and fog extending inland into portions of the inland valleys.

While there are some differences in the details, the global models and their ensemble members generally keep a weak trough of low pressure along the California coast early next week. High temperatures would remain around average with night and morning coastal low clouds and fog extending inland into the western valleys.

AVIATION. 260915Z . Coast/Western Valleys . Low clouds with bases 700-1000 feet MSL and tops to 1300 feet will continue this morning. Areas of vis 3-5SM likely over higher coastal terrain and in western valleys, locally 1SM or less in FG. Scatter out expected by 16-17Z, but some beaches could remain BKN into the afternoon. Low clouds will begin to move into the coastal areas this evening after 04Z with bases near 500-700 feet MSL and lower vis.

Inland Valleys/Mountains/Deserts . Mostly clear with unrestricted vis today and tonight.

MARINE. No hazardous marine weather is expected through Saturday.

BEACHES. Southerly swell arrives Friday, peaks Saturday and gradually lowers Sunday. This will generate elevated surf of 3 to 5 feet with higher sets, along with a high risk of strong rip and longshore currents through the weekend.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Excessive Heat Warning from noon today to 7 PM PDT Friday for Apple and Lucerne Valleys-Coachella Valley-San Diego County Deserts-San Gorgonio Pass Near Banning.

PZ . NONE.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
