Area Forecast Discussion National Weather Service San Diego CA 214 AM PDT Sat Jun 12 2021

SYNOPSIS. High pressure will strengthen and expand over the Desert Southwest through early next week. This will bring a long duration heat wave to much of the region, with the peak of the heat Tuesday through Thursday. A sea breeze and shallow marine layer will keep coastal areas moderated, along with some patchy night and morning low clouds and fog at times. The ridge over the Southwest will slowly weaken late next week, with gradual cooling spreading slowly inland next weekend.

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

.An Excessive Heat Warning remains in effect Monday through Friday for all deserts, with an Excessive Heat Watch for the Inland Empire for the same time period. An Excessive Heat Watch is also in effect Tuesday morning through Thursday evening for inland Orange County, the San Diego Valleys, and all the mountain zones (below 6000 feet).

It was clear across SoCal at 2 AM PDT, with the closest marine clouds off the NW Baja CA Coast. Moderate onshore sfc pressure gradients remained from the coast to the lower deserts, while gradients to the northern deserts had weakened to about neutral. This has maintained the strongest westerly winds to near and below the San Gorgonio Pass where peak gusts of 30-35 MPH were still being reported.

The well-advertised high pressure area is still forecast to build over the Southwest early next week, peaking near the Four Corners areas Tue-Thu. The high will be broad enough to cover SoCal and all of the Southwest with excessively hot days and much warmer nights, except the immediate coast. Circulation around the high will eventually bring some upper-level moisture across SoCal, but at this point, all that is expected are some high clouds.

Onshore flow will be maintained, and that means the coastal areas will be moderated by a sea breeze that is currently supported by widespread coastal sea surface temperatures in the 60s. As a very strong inversion develops and lowers, there will be an increasing chance for patchy low clouds and fog to develop at times along the immediate coast and beach areas.

Looking at the ensemble solutions of the 00Z GFS/ECMWF runs, it isn't clear that the heat will ease much until next weekend or early the following week, especially well inland. Maximum temperature forecast spread increases, supporting the uncertainty. The ECMWF solutions are more bullish with the heat through Saturday before showing much drop in maximum temperatures. Cooling looks more certain as we move through next week and the warm ridge axis weakens and returns to lower latitudes.

AVIATION. 120830Z . Coast/Valleys . Mostly clear skies with unrestricted vis will prevail most of the time through Sat evening, except for patchy BKN clouds along the San Diego County coast 10Z-15Z Sat, with bases 800-1000 ft MSL and tops to 1200 ft MSL and little to no vis restrictions. There is fairly low confidence in stratus reaching KSNA or KCRQ. Low cloud coverage should be slightly more extensive Saturday night, with potential to affect most coastal terminals for a few hours, mainly after 09Z Sun.

Mountains/Deserts . Mostly clear skies with unrestricted vis through Sat night.

MARINE. Northwest winds in the outer waters with a few gusts exceeding 20 knots will continue each afternoon and evening through Monday. Otherwise, no hazardous marine conditions are expected through Wednesday.

FIRE WEATHER. Increasing temperatures and minimum RH values of 10-15% will result in elevated fire weather conditions in the afternoons and evenings. The main concern is as the sea breeze pushes inland with locally gusty winds, especially through and below the desert passes.

Increasing heat and continued gusty onshore flow in the afternoons and evenings will continue elevated fire weather conditions inland late each day through 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.

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-San Diego County Valleys-Santa Ana Mountains and Foothills.

PZ . NONE.
