12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 538 AM PST Wed Feb 19 2020
SYNOPSIS. 19/244 AM.
Low clouds and fog this morning will clear to the beaches otherwise it will be sunny. There will be less low clouds Thursday morning as weak offshore flow sets up. There will be increasing clouds on Friday which will lead to a chance of showers on Friday night. Skies will clear Saturday morning and then remain mostly clear through the weekend. Maximum temps will be near normal today and Friday, above normal on Thursday and then well below normal on Saturday.
SHORT TERM (TDY-FRI). 19/538 AM.
Early Update .
Things are not really going as planned. The eddy has weakened and the offshore flow is stronger. The low clouds have retreated out of the Santa Clarita Vly and are diminishing out of the San Fernando Vly. It looks like the VTA vlys will only get a smattering of low clouds, as will the SLO county coast.
It still looks like the beaches of LA and VTA counties will remain cloudy since the grads will switch to onshore later this morning but now have much less confidence that this will happen.
Updating the forecast to reduce clouds this morning.
Previous Discussion
A weak eddy has increases the marine layer to over 2000 feet. It has covered the LA county coast and vlys as well as the coastal slopes with stratus. There is less stratus across VTA and southern SBA county but the eddy will likely push low clouds into these areas by dawn. Low clouds have also formed over the Central Coast and have pushed into the Santa Ynez vly. The eddy will combine with increasing onshore flow this afternoon to keep low clouds over most of the LA and VTA county beaches. Max temps will be near normal today except a little blo normal across the beaches.
Low clouds will make an early appearance this evening across most of the coastal areas. The clouds will be short lived in many areas as offshore flow develops overnight in response to a large sfc high building into the inter mountain region. By morning its likely that the only low clouds remaining will be over the southern portion of LA county cst. The offshore flow will not be that strong and there should no need for wind advisories. The offshore flow will bring a nice warm up to the area and most areas will come in 3 to 6 degrees above normal.
On Friday, an upper low will approach Southern California from the NW. Cloud cover will increase and temperatures will cool back down to normal values. It will be dry save for the higher terrain over SBA and SLO county mtns in the afternoon.
LONG TERM (SAT-TUE). 19/328 AM.
The GFS and the EC agree that the upper low will be near Pt Conception a few hours before dawn on Saturday. It will move fairly quickly to the ENE and by later afternoon it will be over Las Vegas. The best chc for rain will be Saturday morning across srn SBA county, VTA county and LA county. Some wraparound moisture is possible Saturday afternoon over eastern LA County. With southerly flow, there could be enhancement of precipitation over south facing slopes of the mountains. Precipitation amounts should end up on the light side and should range from a pf an 0.10 inch to up to 0.25 inches over the LA and Ventura mountains. Snow levels will lower to around 5000 feet with probably just a dusting to maybe an inch. This event should not affect the major mtn passes in any meaningful way. The upper will track overhead and while no TSTMs are in the forecast the situation will have to monitored as the cold pool could destabilize the atmosphere a little more than currently forecast. Skies should begin to clear in the afternoon. Max temps will plummet due to the clouds, rain and 552 DM hgts.
Dry NW flow will then set up over the state on Saturday night and will persist through Tuesday. Skies should be mostly clear or at worst partly cloudy. Max temps will rise both Sunday and Monday.
The GFS has a pretty good offshore event forecast for Tuesday with generous cold air advection. The EC does not see it that way and is less windy and warmer since it has much less cold air advection.
AVIATION. 19/1330Z.
At 12Z, the marine layer was 2200 ft deep at KLAX. The top of the inversion was near 2800 ft with a temp of 14C.
Low confidence in very complicated forecast. Widespread low clouds in most coastal areas this morning, with less coverage in the valleys. Cigs and vsbys were widely variable, but generally MVFR across L.A. County and IFR to VLIFR elsewhere. However, there were also local LIFR conds in L.A. County in the valleys and foothills. Expect skies to clear by mid morning in the valleys and late morning on the coastal plain. However, cigs may linger near the coast in VTU and L.A. Counties through the afternoon. In coastal areas that do clear, clouds are expected to return early this evening. However, developing offshore flow is forecast to cause clearing overnight, except across southern coastal sections of L.A. County, where cigs should linger through mid morning Thu. Conds tonight will be mostly MVFR across L.A. and VTU Counties and IFR to LIFR across SLO and SBA Counties.
KLAX . Low confidence in the 12Z TAF. There is a 40% chance that cigs will linger through the afternoon. For tonight, expect cigs to return early. There is a 20% chance that skies will stay clear tonight, and a 20% that cigs will clear by 12Z Thu.
KBUR . Low confidence in the 12Z TAF. There is a 40% chance that MVFR cigs will return at times between 13Z and 17Z this morning. There is a 20% chance of IFR cigs between 04Z and 10Z tonight.
MARINE. 19/311 AM.
For the Outer Waters, moderate to high confidence in the forecast. Fairly good confidence that winds will drop below Small Craft Advisory (SCA) levels by mid morning. There is a 30% chance of SCA level NW winds this afternoon and evening. Winds are seas are expected to be below SCA levels late tonight thru Fri night. SCA level winds are likely from late Sat morning through Sun. There is a 20-30% chance of Gale force winds Sun.
For the Inner Waters north of Pt. Sal, winds and seas will likely remain below SCA levels late tonight thru Sat morning. There is a 30% chance of SCA level NW winds Sat afternoon and evening, then SCA level NW winds are likely Sun.
For the Inner Waters south of Pt. Conception, winds and seas will likely remain below SCA levels thru Sat, except for a 30% chance of SCA level W-NW winds across western portions of the SBA Channel Sat afternoon. SCA level winds are likely in the SCA Channel Sun.
LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . Small Craft Advisory in effect until 9 AM PST this morning for zones 670-673-676. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (FRI-TUE).
A cold storm system could bring rain and mountain snow to the region Friday night and Saturday. There is a chance of gusty north to northeast winds Monday and Tuesday.
