Area Forecast Discussion National Weather Service San Diego CA 844 PM PDT Fri Jul 3 2020

SYNOPSIS. High pressure building over the Southwest will bring warmer weather this Holiday weekend. This will be followed by gradual cooling next week as another trough develops along the West Coast. A shallow marine layer this weekend means any low clouds and fog that form at night, will be mainly along the coastal strip. As the marine layer deepens next week, low clouds and modest cooling will work farther inland.

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

After a clear early evening, satellite imagery shows a narrow strip of low clouds developing along the San Diego County Coast. the 00Z Miramar sounding had a 5.5C inversion based near 1400 Ft MSL. This indicates the marine layer has settled another 500 FT. The layer was still quite dry though with a PW of 0.37 inch. Moderate onshore sfc pressure gradients prevailed this evening, and westerly winds of 15- 25 MPH with higher gusts, persisted in wind-prone mtn/desert areas.

The forecast looks on track for additional warming and a shallow stratus/fog layer later tonight. No forecast updates planned.

From previous discussion .

Warmer weather is on the way for the weekend as an upper high currently centered over southeast New Mexico shifts west- southwest towards northern Baja, flattening and weakening slightly as a trough passes through the Pac NW. Highs will return to around normal for the Fourth of July, then becoming a few degrees above normal on Sunday. The ridge weakens further on Monday for a degree or two of cooling. The marine layer will become even more shallow with the potential for patchy dense fog on the coastal mesas tonight into Saturday and near the coast Sunday and Monday mornings.

A trough quickly passes by to the north Tue and Wed for continued cooling, albeit minor, and some deepening of the marine layer. Slow warming for Thursday with greater warming Friday as a stronger ridge of high pressure develops over the Southwest. Highs Friday should be similar to this Sunday, with even hotter conditions possible into next weekend.

GFS ensembles have come more in line with the EC ensembles regarding onset of monsoon moisture by Sunday July 12, though the location and strength of the upper high is vastly different. The deterministic EC is on the stronger high/hotter edge of the ensemble solutions, though the 12Z deterministic run has a slightly weaker high center than the 00Z run did. The position of the high in the EC solutions could suppress convection over So Cal, while the high in the GFS is in a slightly more favorable location for convection. Will have to continue to see if we will end up with monsoon activity or oppressive heat beyond next Friday.

AVIATION. 032005Z . Coast/Valleys . Areas of clouds with bases 500-800 FT MSL will develop overnight and spread locally inland, with areas of 1- 3SM in BR and locally below 1SM in FG. Clear with unrestricted vis by 16Z Saturday.

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 generate high surf over the Holiday weekend, along with strong rip and longshore currents. Highest surf will be in Orange County where some 8 foot sets will be likely. 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 include: the north end of Del Mar and the south end of Cardiff in San Diego County, and parts of Seal Beach, Sunset Beach and Newport Beach in Orange 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 from 6 PM this evening to noon PDT Monday for Orange County Coastal Areas.

Beach Hazards Statement from 6 PM PDT this evening through Monday morning for San Diego 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.
