SYNOPSIS
Cooler with a deepening marine layer into the weekend with night and morning coastal low clouds spreading farther into the valleys with slow or limited afternoon clearing near the coast. There will periods of stronger and gusty southwest to west winds for the mountains and deserts during the afternoons and evenings through Sunday. Areas of night and morning marine layer clouds continue into the middle of next week with highs near seasonal averages.
DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...
.SHORT TERM (Today through Sunday)...
Cooling will spread inland today as a weak pressure system moves inland through southern California tonight with the greater cooling expected on Saturday. Saturday high temperatures will be mostly around 5 degrees below average, ranging from the mid 60s near the coast to the 70s to around 80 for the Inland Empire with the 90s for the lower deserts. Sunday will warm slightly with weak high pressure aloft.
The marine layer continues to slowly deepen, to around 1500 to 2000 feet this morning with continued deepening to around 2500 feet expected for tonight into Saturday morning. Coastal low clouds will spread inland into the western valleys this morning, then into portions of the inland valleys for tonight into Saturday morning with not much change for Saturday night and Sunday.
Afternoon clearing near the coast may be limited or slow through the weekend.
Gusty southwest to west winds for the mountains and deserts during the late afternoon through late evening will be stronger today with gusts to 35 to 45 mph and isolated gusts to 60 mph in the northern Coachella Valley below the San Gorgonio Pass.
.LONG TERM (Monday through Thursday)...
Weak low pressure will remain across the area with slight warming for Monday and Tuesday, not much change for Wednesday, then greater warming for Thursday and Friday. The greatest spread in the high temperature guidance for next week is for the valleys and inland Orange County, reflecting greater spread in the depth of the marine layer. In general through the middle of next week, night and morning low clouds will spread inland into portions of the valleys with slow or limited afternoon clearing near the coast. Later next week, the marine layer will become shallower with less spread of coastal low clouds into the valleys.
AVIATION

Coasts/Valleys
Low clouds based 800-1400ft MSL have moved inland up to 15 miles, and may continue to push further through 14z.

Low clouds return again this evening after 01-02z, with slightly higher bases 1500-2000ft MSL and better chances for CIGs and reduced VIS through the Inland Empire after 06z.
Elsewhere...Clear with unrestricted VIS through this morning. Strong west winds over mountains, passes and desert slopes with gusts locally to 35-50kts this afternoon. Mod up/downdrafts with patchy BLDU possible reducing VIS down to 3SM at times, primarily after 18z. Winds slowly weaken through Saturday morning.
