Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 116 PM PDT Wed May 15 2024

SYNOPSIS
15/107 PM.

Consistent weather expected likely into next week. Coastal areas will continue to see low clouds and below normal temperatures.
Interior areas will remain above normal with gusty winds at times, especially across the Antelope Valley. There is a slight chance of showers or thunderstorms for the mountains this afternoon

.SHORT TERM (TDY-SAT)...15/107 PM.

A 20 percent chance of a shower or thunderstorm will persist into the early evening then shut down once the sun goes down. If any shower forms off the mountains, there will be a small but non-zero chance of it drifting off the mountains and into the valleys due to the easterly steering flow. This should be the last day this week of any such threat.

Little change remains on the menu through Saturday. The weak upper level low that has been over the area will depart tonight, with weak ridging forming for Thursday through Saturday. This will bring a few degrees of warming to the interior mountains and valleys on Thursday with little change after through Saturday.
High temperatures between 80 and 90 will be common which is 5 to 10 degrees above normal. On the coastal side of the mountains however, this upper level change should lower the marine layer a little and decrease chances for drizzle, but otherwise have little affect as onshore pressure gradients remain strongly onshore keeping natures air conditioning on full blast. With that said, the marine layer depth and coverage rarely stays exactly the same every day with unpredictable changes, but there is little reason to believe in any major changes. As a result, High temperatures will remain in the 60s at the beaches, to between 70 and 80 inland, which is technically 5 to 10 degrees below normal but not that unheard of for May Gray. Any day-to-day temperature changes will be due to any unpredictable fluctuations of low cloud daytime clearing times.

Onshore wind gusts will increase and expand over the interior areas as they have been each day, with gusts of 20 to 35 mph generally common in the afternoon and evening hours. The winds will be strongest in the Antelope Valley, especially in the foothills, where local gusts to around 45 mph will remain possible. Will keep the low-end Wind Advisory in play as a result.
Winds could be 5 mph or so stronger Thursday and Friday with the stronger onshore pressure gradients. Elsewhere, winds will be fairly seasonal.

.LONG TERM (SUN-WED)...15/108 PM.

A series of small but potent low pressure systems will push through the Pacific Northwest Saturday night through early next week. This will break down the ridging aloft, but now that looks to be delayed until early Monday, with Sunday being very similar to the end of this week. There remains a fair amount of spread in the ensemble solutions in terms of what happens next over our region. Some draw a weak low that is currently 1000 miles west of Los Angeles through southern California, while others drop a rather large trough across eastern California and Nevada. Both outcomes should result in a deepening and expansion of the marine layer Monday through Tuesday or Wednesday with some drizzle and widespread cooling (focused over the mountains and interior). The extent and magnitude of those changes rests in which outcome wins out.

AVIATION
15/1659Z.

At 1630Z at KLAX, the marine layer was 2600 feet deep. The top of the inversion was 5400 feet with a temperature of 20 degrees Celsius.

Overall for the 18Z TAF package, high confidence in desert TAFs and moderate confidence in coastal/valley TAFs. For this afternoon, there is a 30% chance MVFR CIGs at KSBA will dissipate and a 30% chance that MVFR will remain at KOXR, KCMA, KSMO and KLAX. For tonight, high confidence in return of CIG/VSBY restrictions, but moderate confidence in timing and flight category.

KLAX...Moderate confidence in 18Z TAF. There is a 30% chance MVFR CIGs will not dissipate this afternoon. For tonight, high confidence in return of CIG/VSBY restrictions, but moderate confidence in timing of category changes (+/- 2 hours of current forecasts) and flight category (50% chance that conditions will remain at MVFR levels). No significant easterly wind component is expected.

KBUR...Moderate confidence in 18Z TAF. Dissipation of MVFR CIGs could be as late as 20Z. For tonight, timing of return of CIG/VSBY restrictions could be +/- 2 hours of current 06Z forecast. There is a 40% chance that conditions will remain at MVFR levels tonight.

MARINE
15/1138 AM.

For the Outer Waters, moderate to high confidence in current forecast. Tonight through Sunday, high confidence in winds and seas remaining below Small Craft Advisory (SCA) levels. For Monday, there is a 30-40% chance of SCA level winds.

For the Inner Waters north of Point Sal, high confidence in current forecast. Tonight through Monday, winds and seas will remain below SCA levels.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. Tonight through Sunday, high confidence winds and seas remaining below SCA levels. On Monday, there is a 30% chance of SCA level winds across the western half of the Santa Barbara Channel.
