SYNOPSIS
A weak low pressure system moving inland through southern California will bring cooling through Friday, gusty southwest to west winds for the mountains and deserts during the afternoons and nights with the stronger gusts to 50 mph, and deepening of the marine layer with night and morning coastal low clouds extending inland across much of the valleys by Friday night. Warming for Saturday and Sunday under high pressure with the marine layer becoming shallower. Then a cooling trend for Monday into the middle of next week as low pressure develops near the West Coast.

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

.SHORT TERM (Today through Saturday)...
Subtropical high clouds will thicken and spread inland across southern California today with a weak low pressure system moving inland through southern California tonight and Friday.

The marine layer will deepen into Friday with coastal low clouds and fog extending inland into the far western valleys this morning, farther into the valleys for tonight into Friday morning, and inland across much of the valleys for Friday night and possibly onto the lower coastal slopes of the mountains.

The will be cooling for today and Friday. High temperatures for the coast and valleys for Friday will be a few to around 5 degrees below average for the coast and valleys with the deserts still around 5 degrees above average. There will be gusty southwest to west winds for the mountains and deserts this afternoon and tonight with the stronger gusts to 40 to 50 mph with another round of gusty winds for Friday afternoon and night with the stronger gusts to 45 to 55 mph. Saturday will be warmer with high temperatures a few degrees warmer to around 5 degrees warmer for the mountains.

.LONG TERM (Sunday through Wednesday)...
High pressure aloft will continue the warming on Sunday with the marine layer becoming shallower and night and morning low clouds and fog patchier and closer to the coast. With the warming, high temperatures near the coast will be a few degrees above average on Sunday to around 8 to 12 degrees above average for the mountains, high desert, and inland valleys. NBM chances for Palm Springs to reach 100 or higher on Sunday have decreased to 65 percent. If Palm Springs doesn't have its first 100 degree day for 2024 on Sunday, it could be delayed until some time in May.

There will be a cooling trend for Monday through Wednesday as a low pressure system develops in the vicinity of the California coast. There remain model differences in the placement and details. NBM has high temperatures on Wednesday cooling to around 5 degrees below average at lower elevations to 8 to 12 degrees below average the mountains and inland valleys. The marine layer is expected to deepen with night and morning coastal low clouds extending inland across much of the valleys by Wednesday and possibly onto the lower coastal mountain slopes. There will also be gusty southwest to west winds for the mountains and deserts for each afternoon and night.

AVIATION
180930Z
Coast/Valleys
Low clouds and fog will continue with bases 500-900 feet MSL and tops to 1200 feet. Vis 0-5SM over mesas and higher coastal terrain. Clearing will occur in most areas 15- 17Z. Low clouds to push ashore after 02Z this evening and into western valleys after 10Z Friday. Bases should be around 1200-1600 feet MSL with local vis reductions along inland extent.

Otherwise...BKN high clouds at/above 20000 feet MSL will continue through 23Z, SCT thereafter. VIS will remain unrestricted.

MARINE
No hazardous marine conditions are expected through Monday.

BEACHES
A long-period swell from the southern hemisphere will continue to bring surf up to 6 feet this morning, especially on south-facing beaches, before gradually subsiding thereafter. This will generate a high rip current risk.
