Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 232 PM PDT Tue Apr 30 2024

SYNOPSIS
30/149 PM.

Mostly clear skies and warmer temperatures will prevail across the region through this week, although some night through morning coastal low clouds and fog can be expected at times. Locally breezy winds will continue over the mountains and deserts through Wednesday, then turn NE over interior portions of Ventura and Los Angeles Counties Wednesday night into Thursday. Cooler temperatures are expected Friday through the weekend with a slight of rain.

.SHORT TERM (TDY-FRI)...30/202 PM.

Most coast/valley areas are running a little cooler than yesterday as gradients continue to trend onshore. Expecting a similar trend again Wednesday with slightly higher coverage of marine layer stratus, mainly south of Pt Conception. There's still some lingering northerly flow across the interior but those gradients are weakening and winds tonight should mostly be below advisory levels.

The biggest adjustment to the forecast today was to cut back on the offshore winds for Thursday as models (particularly the NAM)
have really reversed course on that. Onshore flow will be lighter but any northeast winds should be confined to the interior and be well below advisory levels. High temperatures will only go up a few degrees at most for Thursday, mainly mid 80s for the valleys and low to mid 70s for coastal zones. Then turning cooler again Friday as a trough approaches from the northwest and gradients shift back to onshore again marine layer coverage expands.

.LONG TERM (SAT-TUE)...30/221 PM.

Still a lot of uncertainty this weekend with the approaching upper low. The deterministic models are still split with the GFS favoring an inside slider low dropping through interior California while the EC keep the low mainly north of Lake Tahoe. The grand ensemble mean solution is much closer to the farther north EC solution and not surprisingly NBM pops are extremely low. This may ultimately prove to be an accurate assessment of the rain chances at this point there are still enough solutions with at least some light rain or drizzle to have some mention of precip in the forecast by later Saturday into Sunday. For what it's worth all the higher precip solutions from the earlier GEFS solutions were gone on the 12z run and only 30-40% of the remaining solutions had even light rain, perhaps indicating models are starting to move towards a drier scenario for the weekend.

In any case, rain chances are mostly confined to late Saturday and early Sunday so the majority of the daytime periods are expected to be dry. The cooling trend that will have begun Friday will continue through the weekend with highs 4-8 degrees below normal, coolest on Sunday.

There will be slightly warming Monday but most models maintain cooler than normal temperatures well into next week.

AVIATION
30/1851Z.

At 1122Z at KLAX, the marine layer was 1800 ft deep with an inversion top at 3500 ft and a maximum temperature of 16 C.

Moderate confidence in LA County coast and valley TAFs. Low confidence on KSBA, KOXR, and KCMA, with a 20% chance of no cigs developing, and a 20% chance cigs a category lower than forecasted. High confidence in all other TAFs. Timing of cig arrival/clearing may be off by +/- 2 hours, with a 20% chance of cig developing once category lower than forecast at times.

KLAX...Moderate confidence in TAF. Timing of cig arrival/clearing may be off by +/- 2 hours, with a 20% chance of a couple hours of cigs lowering to BKN008. There is a 20% chance of an east wind component reaching 6-8 kts from 08Z-16Z Wed.

KBUR...Moderate confidence in TAF. Timing of cig arrival/clearing may be off by +/- 2 hours, with a 20% chance of a couple hours of cigs lowering to BKN008.

MARINE
30/929 AM.

For the outer waters, current Gale Warnings are on track with gusty NW gales expected to continue until late tonight. Swell will continue to be steep and choppy. After gales subside, Small Craft Advisory (SCA) conds are expected for the outer waters, Wednesday through Sunday. However, there is a 30% chance of gales persisting into Wednesday night and resurfacing again Thursday afternoon and evening.

For the inner waters N of Pt. Sal, SCA level winds are likely through tonight. Then, there is a 60% chance of SCA winds during the afternoon and evening hours Wednesday through Friday. Seas are expected to be above SCA level through Wednesday.

For the Santa Barbara Channel, SCA level W-NW winds are expected across the western portion during the afternoon through late night hours today and Wednesday. Then, there is a 20-30% chance of SCA winds each afternoon/evening Thursday and Friday across the extreme western portion. Winds will likely remain below SCA levels for eastern portions of the channel through Friday night.
Saturday afternoon through Sunday, there is a 30-40% chance of widespread W to NW SCA level winds across the entire inner waters.

For the southern inner waters, there is a 20% chance of SCA level W to NW winds across northwestern portions, near Anacapa Island during the late afternoon through late evening hours through Wednesday. Otherwise, good confidence in conds remaining below SCA levels through Friday night. Saturday afternoon through Sunday, there is a 30-40% chance of widespread W to NW SCA level winds across the entire inner waters.
