Area Forecast Discussion National Weather Service San Diego CA 202 PM PDT Mon Sep 27 2021

SYNOPSIS. A deep marine layer will persist through Wednesday morning with well below average high temperatures in the valleys and below average high temperatures elsewhere. Areas of mainly upper level smoke will spread southward across the area through Tuesday. Weak Santa Ana winds are forecast by Thursday, which will bring warmer and drier conditions with gusty northeast winds near the coastal mountain slopes and below passes and canyons. Much warmer and dry conditions will continue into the weekend as winds lighten.

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

-Forecast Highlights-

* Below normal temps, solid marine layer through Wednesday morning * Weak Santa Ana winds/Elevated fire weather conditions Thursday * Turning much warmer Thursday-Sunday

Marine layer low cloudiness is holding on tight from the coast and across much of the valleys this afternoon. Clearing has occurred over much of the Inland Empire, but the current GOES satellite loop is not encouraging on much, if any, clearing elsewhere where the clouds are socked in. Patchy mist/drizzle continues. Clouds will fill back inland to cover the IE overnight with clouds remaining for the coast. This marine layer will remain in place through Wednesday morning as onshore winds strengthen with an incoming longwave trough from the northwest. A coastal eddy may even develop over the California Bight. This would only provide more vigor to this marine layer. Patchy drizzle will again likely occur tonight into Tuesday and is a possibility all the way through Wednesday morning.

HRRR shows smoke aloft from the southern Sierra wildfires moving across Southern California through Tuesday night. This will lead to hazy skies. Surface smoke won't be high though as most of the smoke is elevated, but there is some small amounts of near surface smoke. So even where it is clear inland, haze will prevail and may even be cloudy for a time.

Clearing will occur Wednesday afternoon behind the trough. Surface high pressure will build into the Great Basin and this will lead to weak Santa Ana winds developing Wednesday night through Thursday afternoon. East to northeast gusts of around 30 mph is expected below the passes and canyons and along the coastal mountain slopes, peaking Thursday morning through afternoon.

Winds will relax Friday through the weekend while getting hotter as upper level ridge builds in from the west. Just how hot it gets is uncertain, case in point at San Diego where the spread is from 79 degrees to 90 degrees on Saturday off the ECMWF ensembles. No matter what, it will be a noticeable change, especially for the coast/valleys. Followed close to NBM in the extended with just a nudge towards the hotter guidance based on precedence.

AVIATION. 272015Z . Coast/Valleys . P6SM OVC015-020 and tops 030 with areas of VIS 3-5SM in -DZ/BR. Patchy VIS AOB 1SM in -DZ/BR/FG developing far inland overnight with higher terrain locally obscured. The risk of bkn-ovc conditions at KSAN this evening is moderate to high so confidence in KSAN low cloud forecast is moderate to high. After 18Z Tuesday P6SM with areas of SCT-LCLLY BKN025, except remaining BKN- OVC020-025 within 5-10 miles of the coast.

Mountains/Deserts . Mostly clear with scattered clouds AOB FL100.

MARINE. Northwest winds will increase Tuesday afternoon over the outer coastal waters, with gusts near 20 knots possible. Otherwise, no hazardous marine weather is expected through Friday.

BEACHES. A long-period south-southwest swell and a modest west-northwest swell will bring elevated surf and a high rip current risk to the beaches into Tuesday. Sets to 6 feet are possible at Orange County beaches, and sets to 5 feet are possible at San Diego beaches. The south swell will gradually diminish Tuesday through Wednesday, though the west-northwest swell will continue the elevated surf and the high rip current risk in San Diego County on Wednesday.

FIRE WEATHER. Weak Santa Ana winds on Thursday will bring warmer and much drier conditions for inland areas with locally gusty northeast winds near the coastal slopes of the mountains and below passes and canyons. Lowest humidity on Thursday will be 10 to 15 percent over the inland valleys and deserts and generally 15-20% over the mountains. East to northeast wind gusts to around 30 mph is favored. The combination of low humidity and gusty winds will bring elevated fire weather conditions the lower coastal slopes of the mountains, the inland valleys, and inland Orange County on Thursday.

It will continue warm and dry into the weekend but with weaker winds. Weak onshore flow may return during the weekend which would bring a greater recovery in humidity for the coast into the valleys.

SKYWARN. Skywarn activation is not needed.
