Area Forecast Discussion . Corrected National Weather Service San Diego CA 317 AM PDT Thu Jul 9 2020

SYNOPSIS. Seasonal weather will prevail again today, with morning low clouds into the western valleys. Friday will begin a sharp warm-up inland as high pressure expands over the Southwest, limiting the lox cloud coverage inland each night. For the weekend expect fair and hot weather inland, while the sea breeze keeps the weather moderate, with areas of low clouds at times along the Coast. Cooler next week as the high weakens and a weak trough develops over the State.

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

Low clouds were gradually filling into the western valleys overnight and were widespread offshore. Moderate, onshore sfc pressure gradients were holding, supporting westerly wind gusts in excess of 35 MPH through and below the passes.

Today is shaping up to be another mild July day overall for SoCal with maximum temperatures about average. The low clouds should burn off by late morning with fair skies expected for the afternoon and evening.

A strong high pressure center will begin to build over NM today and peak on Saturday around 600 DM at 500 mb. The center is far enough east so that SoCal will continue to experience onshore flow and a cooling sea breeze for coastal areas. Away from the coast though, it will become increasingly hot as the high builds, prompting an Excessive Heat Warning for the deserts. The inland valleys will be hot as well and may require the issuance of a heat product as well for the Sat/Sun period.

The high will deflate early next week, with slow cooling beginning on Monday. Maximum temperatures on Sat/Sun will be 5-10F above average, but should be back to near average by Tuesday. The high will remain subdued until late next week when it is forecast to rebuild over the Mississippi Valley. With another ridge forecast over the far EastPac, that leaves weak troughing along the West Coast. This is confirmed by a consensus of both GFS/ECMWF Ensemble members which show the warmest weather will come this weekend, followed by cooler conditions next week and into the following week. They also suggest that after some mid-level moisture arrives this weekend, a dry SW flow will hold any Monsoonal activity at bay through at least mid month.

AVIATION. 090900Z . Coast/Valleys . BKN-OVC skies with cloud cases 800-1,300 ft MSL and tops to 2,000 ft MSL will persist up to 20-25 miles inland from the coast through 16Z this morning, with CIGS gradually clearing toward the coast through 18Z. Elevated terrain at cloud level will be obscured during this period with vis 2-5 SM. Several hours of mostly clear skies should occur at the coast during the afternoon, with low clouds returning between 02-06Z Fri and spreading a similar distance inland. Bases Thursday night will likely be similar in height (perhaps a couple hundred feet lower).

Mountains/Deserts . Mostly clear skies with unrestricted visibility through Thursday afternoon. Gradual increase in mid to high-level clouds late Thursday, above 10,000 ft MSL.

MARINE. Patchy fog with visibility below 1 mile will be possible Friday night and Saturday night. Otherwise, no hazardous marine conditions are expected through Monday.

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 10 AM Saturday to 8 PM PDT Monday 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. 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.
