Synopsis

22/126 PM.

Showers with a slight chance of thunderstorms will continue through this evening. A quiet Friday will transition into a weak Santa Ana Wind event this weekend, bringing drier conditions and warmer temperatures to the region into next week.

Long Term (mon-thu)

22/124 PM.

A weak Santa Ana event will continue into next week, allowing for warmer (near normal high temps) and drier conditions to prevail. Winds will most likely remain confined to the mountains and some valleys. Onshore flow is expected to return around mid week with temperatures returning to normal levels. There are some model solutions indicating a return of wet weather just after Halloween.

Aviation

22/1754Z.

At 1715Z at KLAX, there was no marine layer nor an inversion.

Overall, moderate confidence in 18Z TAF package. Under any showers and thunderstorms MVFR conds is likely. Otherwise VFR conds are expected for the most part.

KLAX...Moderate confidence in 18Z TAF. Conditions should mostly remain VFR with MVFR possible at times. Isolated to widely scattered showers across the area through 23/18Z. Low chance of a thunderstorm or two (10-15%) through this afternoon. Good confidence that any east wind component remains below 8 kts.

KBUR...Moderate confidence in 18Z TAF. Isolated to widely scattered showers across the area through 23/12Z. Low chance of a thunderstorm or two (10-15%) through this afternoon. VFR CIGs expected except MVFR conds possible under any activity.

Marine

22/105 PM.

For the Outer Waters, high confidence in current forecast. Gusty Small Craft Advisory (SCA) level winds likely are likely at times by this evening and continue through Friday night. For Saturday through Tuesday night, winds and seas are expected to remain below SCA levels.

For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is a 20-30% chance of SCA level winds at times through Friday evening. Otherwise, high confidence in winds and seas remaining below SCA levels through Tuesday night.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. Through Tuesday night, high confidence in winds and seas remaining below SCA levels for most areas. The only exceptions will be the western half of the Santa Barbara Channel with a 50-70% chance of SCA level winds late Friday afternoon and evening and a 40% chance of SCA level wind gusts for the southern waters Monday evening.

Through this afternoon into early this evening, scattered showers will affect the coastal waters, with isolated thunderstorms possible for the southern inner waters. Any thunderstorms that develop will be capable of producing gusty/erratic winds, locally rough seas and even waterspouts.
