Area Forecast Discussion National Weather Service San Diego CA 850 AM PDT Thu Jul 2 2020

SYNOPSIS. High pressure to the southeast will bring a warming trend into Sunday with Sunday high temperatures around 5 to 8 degrees above average. This will be followed by a slow cooling trend for Monday through Wednesday with Wednesday high temperatures a few to around 5 degrees below average. The marine layer will become shallower with night and morning coastal low clouds and fog not spreading much farther inland than coastal areas for Sunday and Monday mornings. The low clouds will spread back into portions of the valleys by the middle of next week.

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

This morning looks an awfully lot like yesterday morning with a deep marine layer in place and low clouds blanketing the coastal basin. Clouds have even snuck through the Cajon Pass and are nearly spilling into the high desert. Visible satellite shows clouds have begun to clear along the foothills. The marine layer depth is virtually unchanged from yesterday and the inversion just as strong, so expect slow clearing once again, with coastal areas remaining mostly cloudy through the day. Elsewhere remains clear.

An upper level high currently over northern Mexico will slowly expand northwest towards Southern California into the weekend, bringing gradual warming and highs returning to near normal by Saturday. The marine layer will finally become more shallow, with less inland extent of coastal low clouds each night. There is a chance that the beaches could be mostly cloudy through the day on the Fourth of July, especially in San Diego County.

The center of the high shifts west and over So Cal for Sunday and Monday, bringing greater warming with highs 5 to 8 degrees above normal. Highs in the Inland Empire and high desert will be in the mid to upper 90s, with highs in excess of 110 in the low deserts these days. The marine layer will be shallow enough for patchy dense fog over the coastal mesas and higher coastal terrain on Sunday, and at the beaches Sunday night into Monday, though clouds may be fairly patchy by then.

Slow cooling takes place Tuesday through Thursday with highs near seasonal averages. More expansive and stronger high pressure may develop late next week over the central and southern Rockies into the southwestern states. This would bring a warming trend late next week into next weekend. Monsoon moisture will remain well to the southeast through Friday. The majority of EC ensemble members show moisture beginning to overspread So Cal by Saturday and remains elevated through much of the following week. The 00Z GFS ensemble is on the drier side and holds off until closer to the middle of that week, though there is much spread in the solutions. Interestingly, the 06Z deterministic GFS is more in line with the EC ensembles in terms of moisture. Confidence is lacking at this point, but at least some signs are pointing to the first monsoon push by mid July.

AVIATION. 020900Z . Coast/Valleys . Low clouds with bases 1500-2000 ft MSL will continue to fill into the inland valleys this morning. Reduced visibility of 3-5 miles will occur in the inland valleys where clouds and terrain intersect. Scatter out expected in the valleys 15- 17Z and along the coast from 19-21Z. Some patchy low clouds could linger along the beaches through the afternoon. Low clouds will move back in after 03Z, with lower bases and less inland extent.

Mountains/Deserts . Mostly clear with unrestricted vis through today.

AVIATION. 021530Z . Coast/Valleys . Low clouds with bases 1500-2000 ft MSL and tops to 2800 ft MSL cover most of the region west of the mtns. Reduced visibility of 1-3 miles will occur where clouds and terrain intersect. Clearing expected inland 15-17Z and along the coast from 19-21Z. Some low clouds will likely linger along the beaches through the afternoon. Low clouds will again increase in coverage and spread inland after 03Z friday, with lower bases and tops not reaching as far inland.

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

MARINE. No hazardous marine conditions are expected through Wednesday.

BEACHES. Long-period southwest swell will continue 3-6 ft surf through today, with the highest surf in Orange County. A larger southwest swell with a 16-18 sec period will begin to build in Friday and generate even higher surf over the Fourth of July holiday weekend along with strong rip and longshore currents. Highest surf again will be in Orange County where some 8 foot sets will be likely.

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

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