Area Forecast Discussion National Weather Service San Diego CA 919 PM PDT Sun Jun 2 2024

SYNOPSIS
A weak trough over the West Coast will keep a deep marine layer in place through Monday. Pockets of drizzle are likely in some coastal and valley areas late tonight through early Monday morning. High pressure building over the Great Basin Tuesday through Thursday will bring warmer weather to the valleys and mountains, and hot weather to the deserts midweek. Cooler next weekend with increasing onshore flow and a deeper marine layer.

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

Evening update...
Satellite water vapor imagery shows an upper level low off the coast of British Columbia with broad low amplitude troughing across the West and widespread high clouds extending into So Cal.
Low clouds stuck to many portions of Orange and San Diego Counties through the day and have already begun to spread back inland. The 00Z KNKX sounding shows the marine inversion based near 2600 ft MSL, down substantially from around 3500 ft MSL this morning. A coastal eddy is forecast to spin up again tonight which could help the marine layer deepen. Either way it will be sufficiently deep to extend into the inland valleys with some spotty drizzle overnight.

Previous discussion...
From Tuesday through Thursday a 592 dm ridge builds over the eastern Great Basin. This ridge position will bring hotter days to the deserts where high desert highs Wednesday and Thursday will range from 97-103. Heat Risk values in this area meet the criteria for an Excessive Heat Watch which was issued today and will be in effect Wednesday and Thursday. Affected communities include Victorville, Hesperia, Apple Valley, Barstow and Yucca Valley.

The Lower Deserts will also be hotter midweek with highs from 105- 110 at Palm Springs, Coachella and Thermal. Mountain areas will be warmer with highs from 80-90, as will the eastern portion of the Inland Empire with highs from 90-95. Warming in the coastal areas and the western valleys will be tempered by the marine layer and the cooling onshore sea breeze. Highs will range from the upper 60s at the coast to the upper 70s ten miles inland.

Latest guidance suggests a slower breakdown of the ridge high pressure over the Great Basin later this week, and the desert heat may persist into Friday before being forced east by a deepening closed low over north-central Baja. This closed low, cut off from the jet stream, will slowly meander north-northeast across northern Baja Saturday, then cross into either Southern California or Arizona Saturday night and Sunday. This trough may generate isolated convection but that will depend on the instability and moisture parameters, and the ultimate track of the low.



AVIATION
030415Z
Coast/Valleys
BKN-OVC low clouds with bases 1500-2500 ft MSL with tops to 3000 ft MSL will prevail in all coastal areas and spread through most valleys by 09Z Mon. Higher terrain will be obscured in clouds at times, with local VIS 2-4 miles in the valleys 08Z-17Z Mon. Clearing will occur Mon 16Z-20Z in the valleys and 18Z- 22Z near the coast, with areas of BKN clouds continuing near the immediate coast through Mon afternoon. Low clouds will spread a little less far inland Mon night.

Mountains/Deserts...Occasional SCT-BKN high clouds at/above 20000 ft MSL will continue with unrestricted VIS through Mon evening.
West winds with gusts 25-40 kt will continue through 10Z Mon from the mountain crests east through the desert slopes and into the deserts, including through/near San Gorgonio Pass with MOD UDDFS.

MARINE
No hazardous marine conditions are expected through Friday.

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



SGX WATCHES/WARNINGS/ADVISORIES
