Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 833 PM PDT Tue May 7 2024

SYNOPSIS
07/212 PM.

Gusty northwest winds will turn northeast Wednesday into Friday.
Generally clear skies will continue through the week except for some coastal low clouds and fog. Temperatures will remain around to just above normal through early next week, with highs in the 70s to lower 80s common.

.SHORT TERM (TUE-FRI)...07/745 PM.

***UPDATE***

Clear skies covered the forecast area early this evening. There were some low clouds noted along the SAN County coast and these should expand some and move up the coast tonight as an eddy develops. By late tonight, portions of the L.A. County coast should have some low clouds and fog. Otherwise, the clear skies will continue across the forecast area overnight.

Good northerly gradients this evening (e.g., -3.9 mb SBA-SMX at 02Z) were helping to bring gusty north winds to the southern SBA County coast and Santa Ynez Mtns. Gusty NW to N winds will also affect portions of the the SBA/VTU/L.A. County mtns into the Antelope Vly and Santa Clarita Vly overnight. Wind gusts to Advisory levels are expected, and a series of Wind Advisories (LAXNPWLOX) are in effect thru late tonight for all these areas.
Elsewhere over portions of SLO/SBA Counties and some of the foothills of VTU/L.A. Counties, breezy N to NE winds will prevail overnight towards daybreak.

The current zone forecasts are in good shape and do not anticipate any updates this evening.

***From Previous Discussion***

Cold air is starting to be deposited over the Great Basin, and will continue to over the next few days thanks to a large low pressure system over the Dakotas that will wobble to the west.
This will cause the winds to abruptly turn to northeasterly later tonight, and remain dominant during the night and morning hours through Friday (with onshore flow each late afternoon). These winds will peak in strength on Wednesday, then gradually decrease each day through Friday. During their peak, gusts should generally vary between 25 and 40 mph over the favored mountains and valleys of all counties, but especially over Los Angeles and Ventura Counties. Isolated gusts to 50 mph should be expected, but do not look widespread enough at this point to warrant any Wind Advisories. These winds also do not look potent enough to punch through the marine layer and down into the beaches. This means that there is still a window for some low clouds and fog each morning along the coast, which looks to expand in coverage each day as southeast winds strengthen. In fact, the pattern is right for a southerly surge on Thursday morning where any low clouds that form south of Point Conception moves north around the point and into the Central Coast.

Expect temperatures to climb tomorrow thanks to the offshore flow and clear skies. This is especially the case for the valleys, where our local climatological guidance suggests temperatures around 80 will be common in most valleys. Coastal areas will be at the mercy of the marine layer, but look to warm up as well since any clouds should clear by the afternoon.

.LONG TERM (SAT-TUE)...07/208 PM.

Ensemble models have a range of outcomes over the weekend, concerning where the wobbling upper level low wants to go. The most likely outcome is for steady increase of onshore flow bringing more cool coastal clouds and gusty onshore winds over the interior. To what magnitude however is still on the table. The first half of next week, looks fairly benign, except for likely continued strengthening of the onshore flow over the mountains and interior, with further expansion of low clouds on the coastal side. There are some indications of some warming for the second half of next week with high pressure building in.

For KPMD and KWJF, there is a 40% chance of MVFR VSBYs in blowing dust through 04Z.

KLAX...Moderate confidence in the 00Z TAF. Timing of cig changes may be off by +/- 2 hours, and there is a 20-30% chance of no cigs developing at all. An easterly wind component up to 8 knots is expected between 09Z to 16Z, with just a 10% chance of the east wind component reaching 10 kts during this time.
