Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 609 PM PDT Mon Jun 1 2020

Updated Aviation Section

SYNOPSIS. 01/158 PM.

Skies will be partly to mostly cloudy through Wednesday and then partly cloudy for the rest of the week. Afternoon temperatures will heat up quite a bit through Wednesday then cool to near to slightly below normal Friday and Saturday. Gusty northwest winds expected for the weekend and warming temperatures into early next week.

SHORT TERM (TDY-THU). 01/136 PM.

An upper low about 600 miles southwest of LAX continues to spin and send high clouds our way. Expect this to continue through at least Tuesday night, after which models indicate decreasing humidities aloft and likely more sunshine. Until then expect periods of cloudy skies alternating with periods of decent sunshine.

Also over the next couple days a high pressure ridge to our east will shift slightly west and warm the air mass. This coupled with weakening onshore flow and thinning clouds aloft should lead to a sizable increase in daytime temperatures for most areas, peaking Wednesday. Valleys could see 100+ and inland coastal zones will get close to 90. Might be close to heat advisory criteria for inland areas but will hold off another day to get a better read on the cloud coverage and strength of the ridge and gradients.

The warm up will quickly reverse Thursday as onshore flow returns and a strong eddy develops. Will likely see low clouds returning to areas south of Pt Conception with slow afternoon clearing and much cooler temps.

LONG TERM (FRI-MON). 01/154 PM.

The eddy circulation will continue into Friday as the upper low moves onshore somewhere between Pt Conception and the MX border. The marine layer will likely deepen to 3000-5000' and clouds pushing well up the south facing coastal slopes. This pattern often results in morning drizzle for many areas south of Pt Conception but either way expect additional cooling with highs dropping a few degrees below normal in most areas and very slow clearing.

The upper low will move east over the weekend and models are showing a pretty strong northwest flow developing behind it. If current gradients hold winds would easily be advisory level in srn SB County, the I5 corridor and the Antelope Valley, and near advisory for the Central Coast.

A broad upper level trough will develop along the coast late in the weekend and continue through early next week maintaining gusty west to northwest winds in the same areas. Temps will climb back to normal levels by Sunday or Monday. Mostly clear skies through the period except possibly some marine layer clouds in coastal LA County.

Looks like temperatures will bounce back up to above normal levels for the latter half of next week as high pressure returns and onshore flow weakens.

AVIATION. 02/0107Z.

At 23Z, the marine layer depth was around 600 feet deep at KLAX. The top of the inversion was near 1300 feet with a temperature near 25 degrees Celsius.

Moderate-to-high confidence in the current forecast. Less confidence in flight categories for coastal terminals. Higher confidence for timing for coastal terminals and in timing and flight categories for terminals away from the coast. There is a chance of LIFR to IFR conditions at coastal terminals highest for coastal terminals north of Point Conception.

KLAX . There is a 30 percent chance of LIFR to IFR conditions between 10Z and 16Z. Otherwise, VFR conditions are expected through the period.

KBUR . VFR conditions are expected through the period. No wind issues are expected at this time.

MARINE. 01/1250 PM.

Gusty west to northwest winds will form by this afternoon and last through tonight over most coastal waters. High confidence that the outer waters from Point Conception to San Nicolas Island will reach Small Craft Advisory (SCA), with low to moderate confidence on if SCA criteria will be met elsewhere. Decided to issue an SCA for the Santa Barbara Channel through the San Pedro Channel anyway as it will be close. A widespread short period swell will dominate the waves as a result. Similar but weaker conditions expected on Tuesday, with a 40 percent chance of low- end SCA from Point Conception to San Nicolas Island. Better confidence in more widespread and stronger SCA level winds on Wednesday, focused from the Central Coast to San Nicolas Island.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . Small Craft Advisory in effect until 3 AM PDT Tuesday for zones 650-655-673-676. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (THU-MON).

Gusty northwest winds are possible in southern SB County and the I5 corridor and Antelope Valley Saturday through Monday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
