Area Forecast Discussion National Weather Service San Diego CA 114 PM PDT Sun Jul 5 2020

SYNOPSIS. High pressure to the south will continue the warming trend today and Monday. Cooler Tuesday through Thursday as a trough of low pressure to the north strengthens the onshore flow and weakens the high. Patchy night and morning low clouds and fog near the coast will become more widespread and spread a little farther inland during the middle of the week. For late in the week through next weekend, high pressure to the east will strengthen and expand across southern California bringing a warming trend.

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

A few tiny patches of low clouds are over the coastal waters this afternoon, otherwise skies are clear. Another hot day is in store for the inland areas, with highs generally around 5 degrees above normal. As of 1 PM, temperatures were running around 2 to 5 degrees higher than yesterday, and up to 10 in some of the San Diego County valleys. Not much change for Monday as an upper level ridge of high pressure remains over the southwest US, weakening slightly for minor cooling. Marine layer clouds and fog will remain patchy, with local dense fog possible over the higher coastal terrain tonight should any clouds make it inland.

Cooler weather is on the way for Tuesday through Thursday as an upper level trough passes by to the north, weakening the ridge further. Increasing onshore flow will generate slightly stronger southwest to west winds in the mountains and deserts each afternoon, though winds will remain well below advisory strength. High temps Wed and Thu will be a few decrees below normal. The marine layer will gradually deepen and low clouds should become more organized/widespread, reaching the far western valleys by midweek. There could be a few pockets of dense fog over the coastal mesas or far western valleys Tuesday morning.

For Friday through next weekend, an upper level high centered over New Mexico will strengthen and expand westward across southern California. There are some differences in the placement of the high pressure which would affect just how much warming occurs and whether small intrusions of monsoon moisture might occur. The ECMWF and its ensemble mean are farther west and south with the high with a more west to east orientation. This would be a hotter and drier solution for Southern California. It does indicate some increase in precipitable water over So Cal, however it is mostly above 600 mb, so would just result in some increasing clouds but no shower/thunderstorms. The deterministic GFS remains the weakest/further east for less intense heating and more moisture, but it remains the outlier with its ensemble mean lying somewhere in between. Trended more towards EC/CMC solutions with highs around 115 possible in the low deserts by Sunday.

AVIATION. 051935Z . Coastal Areas . Mostly clear with unrestricted vis this afternoon except for a few patches at the beaches of northern Orange County. Low clouds and fog will return to coastal areas after 06Z Monday, likely with more coverage than last night. Bases will likely be around 600 ft MSL with tops to 1100 ft MSL. Patchy fog with local vis 1-3 miles could develop along elevated coastal terrain after 09Z Mon. Expect clearing by 17Z Monday.

Inland . Mostly clear with unrestricted visibility through tonight.

MARINE. Patchy fog late tonight into Monday morning could result in localized visibility of 1 nautical mile or less at times. Otherwise, no hazardous marine conditions are expected through Friday.

BEACHES. Long-period south southwest swell will continue through tonight along with strong rip and longshore currents. Surf of 5-7 feet with sets to 8 feet are expected along the beaches of Orange and northern San Diego Counties today. Surf will begin to slowly subside tonight dropping to 3 to 5 feet most areas by Monday afternoon. The surf will combine with high tides of 6.4 feet to produce another round of minor tidal overflow at low-lying coastal locations this evening. Locations which could be affected 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.

PZ . NONE.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
