Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 529 PM PDT Wed Aug 5 2020

SYNOPSIS. 05/526 PM.

Night through morning low clouds and fog will continue across the coasts and valleys through late this week, then will begin to recede toward the coast over the weekend. Cooler temperatures are expected Thursday, then a gradual warming trend is expected through the weekend.

SHORT TERM (TDY-SAT). 05/131 PM.

A trough of low pressure will persist along the west coast the next several days. It will be deepest Thursday which will be the coolest day of the week for most areas with highs 4-8 degrees below normal. Marine layer depth will rise to close to 3000' and push up the lower coastal mountain slopes. Clearing will be slow and possibly not at all for some beach areas.

A slight warmup is expected Friday and Saturday but temps will still be a few degrees below normal.

LONG TERM (SUN-WED). 05/140 PM.

The early summer like pattern is expected to continue into next week, though small height rises due to the trough weakening will likely result in slightly warmer temps by mid week but otherwise not much change in the night/morning low clouds and fog pattern and no hint of monsoon flow even through the 10 day forecast. Models still at odds towards the end of next week with the GFS showing the same pattern continuing while the ECMWF still has a trough but much higher heights as a ridge tries to push in from the southwest. Both models are showing a couple of tropical systems developing near the coast of southern Mexico mid to late next week and moving west over the Pacific which may eventually send some swells our way.

AVIATION. 06/0024Z.

At 2330Z at KLAX, the marine layer was 2000 ft deep. The top of the inversion was around 4500 ft with a temp of 24 C.

Moderate confidence overall in the 00Z TAFs. A deepening marine layer will bring low clouds to the coast and valleys overnight. Generally, MVFR conditions are expected, but there is a 30% chance of IFR conditions for all sites. Moderate confidence in timing of cigs onset and clearing, which could occur +/- 2 hour from TAF times.

Gusty SW-W winds will affect the Antelope Valley through much of the period, strongest during the afternoon to evening hours.

KLAX . Moderate confidence in the 00Z TAF. There is a 30% chance that conditions will drop to IFR, mainly during the evening hours. There is a 20% chance of east winds reaching 8 kt between 12z and 17Z Thu morning.

KBUR . Moderate confidence in the 00Z TAF. The onset of MVFR cigs could differ by at least 2 hours from taf time of 08Z. There is a 30% chance of IFR conditions overnight.

MARINE. 05/132 PM.

No changes to the afternoon forecast, although there is low confidence in the threat of SCA strength winds in the western SBA Channel.

From the morning discussion .

Across the outer waters . moderate confidence in forecast. Small Craft Advisory (SCA) level winds are expected thru at least late Thu night, along with rough choppy seas.

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.
