Area Forecast Discussion National Weather Service San Diego CA 300 AM PDT Sun Jun 13 2021

SYNOPSIS. High pressure will strengthen and expand over the Desert Southwest through the middle of next week. This will bring a long duration heat wave to much of the region, with temperatures peaking Tuesday through Friday. A sea breeze and shallow marine layer will keep temperatures moderated in the coastal areas, along with some patchy night and morning low clouds and fog at times. The ridge over the Southwest will keep it hot well inland into next weekend, with cooling expected across the entire region early next week.

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

Marine stratus has become widespread over the outer coastal waters and was developing over coastal through 3 AM PDT. The sfc pressure gradients have increased slightly onshore from last night and will support better low cloud coverage over coastal areas this morning and over the next few days At 2 AM PDT. strongest westerly winds are found near the San Gorgonio Pass at 30-35 MPH.

After some morning clouds/fog over coastal and western valley areas, fair skies are expected to prevail away from the immediate coast each afternoon for the next several days. The marine layer will shrink into Tuesday, providing a better chance for fog along coastal areas. An influx of higher clouds is likely by Tuesday as moisture aloft is drawn north and westward.

Low pressure centered off the PacNW Coast will release it's hold over CA over the next few days as a strong high builds over the Southwest. Little has changed with this advertised scenario, building confidence that this feature will peak over the Four corners area at 600 DM midweek. A SW-NE oriented ridge axis around this high will pass SoCal from south to north late Tuesday, opening the door to easterly flow aloft Wed-Fri. This will spread mid-high level moisture over the region with more high clouds and higher humidity at higher elevations, but current indications are that there instability will be insufficient for any monsoon-type convection.

The main concern will be the heat, which will reach excessive levels inland beyond the reach of a shallow marine layer along the coast. Temperatures will climb above average today, and continue to climb through midweek when temperatures will be some 10-20F above average, except along the immediate coast and beach areas. With the northward passage of the ridge aloft, increasing onshore flow, and a possible coastal eddy may push cooling inland along the coastal plain as early as Wednesday, when forecast temperatures begin to decrease there. Not so much farther inland though. Excessive Heat Warnings are in effect for the deserts, and Heat Watches farther west across the mountains and into the valleys much of the week. A secondary threat is wildfire (See FIRE WEATHER discussion below).

For what it's worth, there is better agreement between the 00Z runs of the GFS/ECMWF models with respect to the deamplification of the strong high over the Southwest later in the week. The center does drift over SoCal as it weakens over the coming weekend, maintaining heat over the deserts as strong, moderating onshore flow prevails west of the mountains. This is echoed by the 00Z ensembles of both models, which show clear cooling trends after Saturday, peaking toward the middle of next week. These ensembles similarly show pronounced cooling at Ontario and John Wayne on Wednesday. The trick will be how far inland this will get. It isn't as evident at San Bernardino. For now, expect the hottest day to be Tuesday, closer to the coast, with a possible increase in temperatures again later in the week if the eddy fades.

AVIATION. 130900Z . Coast . CIGS will become more prevalent along the coast through 11Z Sun, persisting until 15-17Z before clearing. Bases will range between 900-1300 ft MSL, with tops to 1500 ft MSL. Only elevated coastal terrain near cloud level will see vis restrictions. Patchy stratus may redevelop after 14/02Z, mainly along the San Diego County coast, however confidence in impacts to the terminals is low. Coverage may be rather intermittent, and overall low cloud coverage Sunday night should be considerably less, struggling to extend into Orange County. Expect bases Sunday night to be between 600-1,000 ft MSL.

Valleys/Mountains/Deserts . Mostly CLR skies with unrestricted vis through Sunday night.

MARINE. Northwest winds gusting to near 20 knots will develop over the outer coastal waters each afternoon and evening through Tuesday. No hazardous marine conditions are expected later in the week.

FIRE WEATHER. Increasing temperatures and minimum daytime RH values of 10-20% (far inland valleys/mountains/deserts) will result in elevated fire weather conditions in the afternoons and evenings. The main concerns are with the inland push of the sea breeze in the afternoons and evenings, especially through and below the desert passes . and the coming extreme heat (temperatures 15-20 degrees above average), resulting in very high mixing heights, creating the potential for large, plume-dominated fires over the far inland valleys and mountains.

These elevated fire weather threats while not critical, will be greatest Tuesday through at least Friday. Gradual cooling and increasing humidity will help to ease conditions over the weekend and into next week.

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 Monday to 9 PM PDT Friday for Apple and Lucerne Valleys-Coachella Valley-San Diego County Deserts-San Gorgonio Pass Near Banning.

Excessive Heat Watch from Tuesday morning through Friday evening for Riverside County Mountains-San Bernardino County Mountains-San Diego County Mountains-San Diego County Valleys.

Excessive Heat Watch from Monday morning through Friday evening for San Bernardino and Riverside County Valleys-The Inland Empire.

Excessive Heat Watch from Tuesday morning through Thursday evening for Orange County Inland Areas-Santa Ana Mountains and Foothills.

PZ . NONE.
