Area Forecast Discussion National Weather Service San Diego CA 816 PM PDT Sat Jul 4 2020

SYNOPSIS. High surf and strong rip currents will affect area beaches this Holiday weekend. High pressure centered over northwest Mexico will continue the warming trend through Sunday, while a shallow marine layer near the coast keeps the weather moderate with areas of night and morning low clouds and fog. After Sunday, the high will weaken as a trough expands along the West Coast. Look for the marine layer to gradually deepen, spreading modest cooling inland, along with more extensive low clouds and fog. High pressure will become reestablished over the Southwest again late next week, resulting in more hot weather inland, and limiting marine clouds and fog to coastal areas.

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

Aside from a few patches of low clouds along the San Diego County Coast, it was clear over Southern California this evening. Robust onshore sfc pressure gradients were sustaining westerly winds of 20- 25 MPH with gusts 30-40 MPH in the wind-prone mtn/desert areas this evening. The 00Z Miramar sounding indicated the marine layer depth was little changed from yesterday at about 1300 FT MSL. The forecast appears to be on track this evening so no updates planned.

From previous discussion .

The warming trend continues Sunday as the upper level high shifts from a position over southern New Mexico to over So Cal, with highs around 5 to 8 degrees above normal. Low deserts are likely to exceed 110 degrees, and a few locations in the Inland Empire may reach 100. The ridge weakens slightly Monday, allowing high temps to lower by a degree or two. The marine layer will become very shallow and less widespread tonight into Sunday morning and again Sunday night into Monday morning, with patchy dense fog possible in the coastal areas.

An upper ridge begins to strengthen over the Southwest late in the week, though there is still discrepancies regarding the position and strength. Ensemble solutions for both the EC and GFS are still insistent on monsoon moisture pushing into southeast CA next weekend, though it's unclear if it will result in any convection. The 12Z GEFS mean has trended more towards the EC/ECE mean, but remains cooler (relatively speaking) though the position of the high is now less favorable for monsoon convection with the ridge almost directly overhead. Either way it is likely to be hot again next weekend, but whether it will be similar to tomorrow or hotter remains a mystery.

AVIATION. 040300Z . Coast/Valleys . Areas of marine stratus with bases 600-900 FT MSL and tops to 1300 FT MSL will develop along the coast after 06Z with areas of 3-5SM BR and local VIS below 3SM in BR/FG spreading inland up to 15SM by 14Z Sunday.

Mountains/Deserts . Mostly clear with unrestricted visibility through tonight.

MARINE. No hazardous marine conditions are expected through Thursday.

BEACHES. Long-period south southwest swell will continue through the weekend along with strong rip and longshore currents. Surf of 4-6 feet with sets to 8 feet are expected along the beaches of Orange and northern San Diego Counties. The surf will combine with high tides of 6.6 feet to produce minor tidal overflow at low-lying coastal locations each evening through Sunday. Locations most likely to have some flooding this evening and Sunday evening include parts of Seal Beach, Sunset Beach and Newport Beach in Orange County, and the north end of Del Mar and the south end of Cardiff in San Diego County.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . High Surf Advisory until noon PDT Monday for Orange County Coastal Areas-San Diego County Coastal Areas.

Coastal Flood Advisory until 2 AM PDT Sunday for Orange County Coastal Areas.

PZ . NONE.

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.
