Area Forecast Discussion National Weather Service San Diego CA 853 PM PDT Wed Aug 4 2021

SYNOPSIS. The heat wave will continue inland through Thursday. This will be followed by a gradual cooling trend that will spread inland with desert high temperatures returning to near average this weekend. Night and morning coastal low clouds and fog may extend locally into the western valleys for the weekend into early next week.

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

Update:

It was a hot one (understatement) inland and especially across the deserts. Record highs were broken with the hottest readings occurring across the Coachella Valley. Palm Springs and Thermal both topped out at 122F degrees today, breaking the record highs for the date with Thermal even breaking the all time hottest temperature recorded in August (previously 121 on Aug. 5, 1997).

Even the mountains were hot with most mountain locales into the 90s - 96 at Julian, 94 at Mt. Laguna and a record high of 97 at Palomar Mountain.

All of the records are headlined on our webpage weather.gov/sandiego and @NWSSanDiego on Twitter

The strong upper ridge responsible for this heat wave, now centered near Las Vegas will be gradually displaced into southern AZ/NM Fri-Sat while weakening as an upper trough passes by to the north. This will result in gradual "cooling", but not before another scorcher inland on Thursday. It will remain hot inland even into the weekend, but closer to normal levels. Areas closer to the coast will continue to be moderated, thanks to the ocean breezes, e.g. Oceanside Harbor's high today only 71 degrees.

No changes were made to the forecast. See previous discussion below for more forecast details.

Previous Discussion (Issued at 126 PM PDT Wed Aug 4 2021):

Temperatures at 1 pm in the deserts were running several degrees ahead of yesterday's pace at this time. It was 120 at Thermal, looking like that 120-degree barrier will be shattered. If it makes it to 122, that would set a daily record for August (126 is the all-time daily record). 1 pm temps west of the mountains were generally a couple degrees lower than they were yesterday. Low clouds have not fully or only briefly cleared at some beaches today with a strong marine inversion. We may get the same clearing results Thursday as the inversion will remain strong. The marine layer seems to have lifted a few hundred feet, and a similar coastal cloud coverage is expected tonight into early Thursday, with much of the OC remaining in the clear. The high pressure aloft producing our inland heat wave has migrated to center itself over the Las Vegas area today. Then it gets somewhat squashed Thursday by a low pressure trough going through the northwest states. All areas will begin to dial back the heat Thursday as the high pressure relaxes slightly, more noticeable west of the mountains. The weakening high over our region Thursday and Friday and a forming coastal eddy will help the marine layer rebound allowing coasts and valleys to cool sooner than deserts, getting close to normal by Friday. Guidance is pretty certain about gulf surges of surface moisture each morning in the low desert. These would help dampen max temps there, down 3-5 degrees Thursday. The more muggy feeling will be little comfort. Max temps there will gradually approach normal by Saturday. No changes to the heat warnings in deserts and heat advisories in inland valleys, all valid through Thursday. SoCal settles into a pattern with a weak trough off the northwest coast and a weak ridge through the Southwest. That seems to maintain monsoon moisture to our southeast for the most part. Although some increase is noted next week, it's not enough to forecast any chance of precip yet. The marine layer presence will continue, but on the weaker side, typical of August. Overall, look for seasonal August weather without much of a monsoon component next week.

AVIATION. 050330Z . Coast . Low clouds 800-1200 ft MSL currently hugging the SD County coastline will begin to move ashore over the next couple of hours. Vis restrictions of 2-4 SM possible near higher coastal terrain after 10Z as cigs lower 400-700 ft MSL area wide. High confidence in BKN-OVC conditions for KSAN/KCRQ tonight with a bit less confidence for OC as clouds will be patchier near KSNA. SCT conditions expected 15-17Z with mostly clear conditions for late morning into the afternoon on Thursday.

Valleys/Mountains/Deserts . Mostly clear with unrestricted vis through tonight and Thursday.

MARINE. Breezy northwest winds with gusts around 20 kts are possible in the outer waters near San Clemente Island Thursday afternoon and evening. Otherwise, no hazardous marine conditions are expected through Monday.

BEACHES. A south swell of 2-3 ft at 14-16 seconds will continue to generate surf of 3-6 ft and a high rip current risk to the south facing beaches of Orange County and far northern San Diego County through Thursday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Heat Advisory until 8 PM PDT Thursday for Riverside County Mountains-San Bernardino County Mountains-San Bernardino and Riverside County Valleys-The Inland Empire-San Diego County Mountains-San Diego County Valleys.

Excessive Heat Warning until 8 PM PDT Thursday for Apple and Lucerne Valleys-Coachella Valley-San Diego County Deserts- San Gorgonio Pass Near Banning.
