Area Forecast Discussion National Weather Service San Diego CA 339 AM PDT Tue Sep 28 2021

SYNOPSIS. For today, high temperatures will remain below average and well below average in the valleys. The deep marine layer will continue with patchy morning drizzle for the coast and valleys. Stronger onshore flow will bring gusty southwest to west winds to the mountains and deserts during the afternoon and evening. Weak offshore flow on Thursday will bring much warmer conditions. It will be much drier inland with with locally gusty north to northeast winds along and near the coastal slopes of the mountains. Continued warmer with weak winds for Friday through the weekend. Early next week, a weak low pressure system may move inland through California bringing cooling and more coastal low clouds.

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

SHORT TERM (Today through Thursday). A trough of low pressure will move inland through the western states today with stronger onshore flow for southern California. There will be stronger and gusty west winds of the mountains and deserts, strongest during the afternoon and evening with gusts to 40 to 50 mph in the windier locations.

There is also weak coastal eddy. The marine layer is near 3500 to 4000 feet with widespread coastal low clouds extending inland and onto the lower coastal slopes of the mountains. Cloud bases are around 2000 feet MSl with a saturated layer around 1500 to 2000 feet deep. There is once again patchy drizzle from the marine layer with the greatest coverage of light measurable amounts in the San Diego County valleys and the coastal foothills of the Santa Ana Mountains.

Today will be another day with cooler than average high temperatures with some of the valleys 10 to 15 degrees below average. Warmer for the valleys on Wednesday as the marine layer begins to decrease in depth.

For Thursday, there will be high pressure aloft over California with weak offshore north to northeasterly flow across southern California. Thursday will be warmer with the greatest warming for the western valleys into the inland coastal areas. It will also be much drier inland for the mountains, deserts, inland valleys, and inland Orange County with lowest humidity falling to 5 to 10 percent.

There will also be locally gusty north to northeast winds along and near the coastal slopes of the mountains during Thursday morning, diminishing during the afternoon with the stronger gusts to around 35 mph. The lower level flow may have enough of a northerly component such that the stronger and more widespread winds in the local area will be near and below the Cajon Pass and near the coastal foothills of the Santa Ana Mountains with less wind for San Diego County. ECMWF ensemble guidance for Ontario has changed little with the bulk of the members supporting weaker winds with around 20 percent of members supporting moderate strength winds.

The HRRR smoke model shows smoke and haze decreasing from the northwest during the day today. More smoke and haze from the north will spread south and southwestward across the area for late tonight into Wednesday.

LONG TERM (Friday through Monday). Weak high pressure aloft will be across southern California on Friday with a weak low pressure system approaching California from the northwest. This may develop into a weak closed low off the California coast for the weekend. Inland areas may continue to slowly warm for Friday through Sunday. There remains greater spread in the high temperature guidance for the coast and valleys though the deterministic NBM high temperatures for the coast and valleys don't change much through the weekend. Early next week, that weak low pressure system may move inland through California spreading cooling inland and bringing more coastal low clouds.

AVIATION. 281010Z . Coast/Valleys . Widespread OVC stratus with bases 1800- 2800 ft MSL and tops to 5000 ft MSL will continue through the early morning hours with higher terrain obscured. Below the cloud bases, local vis 3-5 miles in DZ will occur. High confidence in slow clearing today 17Z-20Z in the eastern valleys, 20Z-23Z 10-20 western valleys and Orange County. Some locations remaining BKN/OVC within 10 miles of the coast, especially VCTY KCRQ/KSAN. Widespread cloud coverage looks fairly similar again tonight.

Mountains/Deserts . Mostly clear with unrestricted vis through Tue night. Terrain obscurations will occur at times in clouds/fog through 18Z Tue on the coastal slopes below 5000 feet MSL. Areas of west surface winds 20-30 knots with gusts to 45 knots will develop on the desert mountain slopes and through San Gorgonio Pass Tue after 18Z and continue Tue night. Areas of the high desert and KPSP/KTRM gusting close to 25 kts at times.

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

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 through Wednesday. Widespread surf of 2 to 4 feet expected with sets up to 5 feet in San Diego County. Surf will subside slightly toward the end of the work week.

FIRE WEATHER. A low pressure system moving inland through the western states today will bring gusty southwest to west winds to the deserts onto the desert slopes of the mountains. Winds in the windiest locations will gust to 4o to 50 mph during the afternoon. The winds will diminish from north to south during the evening.

For Thursday, high pressure aloft will be over California with weak offshore flow for southern California. It will be much warmer, and much drier inland with humidity falling to 5 to 10 percent in portions of the deserts, mountains, inland valleys, and inland Orange County.

There will also be locally gusty north to northeast winds along and near the coastal slopes of the mountains. The winds will be most widespread during the morning, then diminish in the afternoon. The lower level flow may have enough of a northerly component such that the stronger and more widespread winds in the local area will be near and below the Cajon Pass and near the coastal foothills of the Santa Ana Mountains with less wind for San Diego County. ECMWF ensemble guidance for Ontario has changed little with the bulk of the members supporting weaker winds with around 20 percent of members supporting moderate strength winds.

The combination of wind and low humidity will bring elevated fire weather conditions on Thursday along and near the coastal slopes of the mountains.

Continued warmer and very dry for Friday, but with weak winds. There may be a slight recovery in humidity for the weekend. A weak low pressure system may move inland through California early next week spreading cooling inland and bringing a greater recovery in humidity.

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