Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 330 AM PDT Wed Aug 17 2022

SYNOPSIS. 17/218 AM.

Above normal temperatures will continue through most of the week, peaking today before slowly cooling the rest of the week. Skies will be mostly clear except for night through morning low clouds and fog, mostly along northern coastal areas.

SHORT TERM (TDY-FRI). 17/317 AM.

A 592 dam upper high sits atop of the SW corner of ID with 590 dam hgts over CA. Gradients are weakly onshore and will become moderately onshore as the sfc pressure follows the diurnal curve. The marine layer is 800 ft deep and marine layer stratus covers most of the beaches with the notable exception of the LA beaches. The marine layer is shallow enough to produce some dense fog esp near the beaches. The onshore push in the afternoon will be 1 to 3 mb stronger than ydy and this will allow 3 to 6 degrees of cooling across the coast and to a lesser degree the vlys. The interior will not cool and heat advisories continue for the Cuyama Vly and the interior SLO Vly. Max temps away from the beaches will be 2 to 4 degrees above normal while the interior will be about 6 degrees above normal.

Short range ensemble forecasts agree that the cooling trend will persist into Thursday as will the coastal marine layer stratus pattern. Temps across the csts/vly will cool another 2 to 5 degrees mostly due to another mb increase in the onshore flow. Interior temps will change little as hgts do not change. The upper level flow is not conducive to a monsoon push and all afternoon convection will be to the east of the area.

There is a change in the upper pattern on Friday as upper high over the Great Basin moves to the east and another upper high noses in from the west. Not much actual change however as hgts remain near 590 dam. This is reflected in a temperature fcst that is very similar to Thursday's. There will also be a similar morning stratus pattern. The new upper level flow pattern also does not support afternoon convection.

LONG TERM (SAT-TUE). 17/329 AM.

Both the GFS and the EC deterministic as well as their respective ensembles agree that the EastPac upper high will continue to nose into the state from the west during the extended period. At the same time sfc high pressure to the west will increase with a resultant increase in onshore flow across Srn CA through Sunday and then they will slightly decrease early next week.

The increase in onshore flow should result in an increased night through morning low clouds, but with SSTs running above normal there may not be quite as much clouds as there would be by our normal SST climate.

Max temps will cool both Saturday and Sunday as the upper high weakens and onshore flow (along with the marine layer) increases. Max temps will be below normal by 1 to 3 degrees. Max temps will rebound Monday as hgts rise and onshore flow weakens. The max temp ensemble mean indicates little change on Tuesday.

AVIATION. 17/0543Z.

At 0445Z at KLAX, the marine layer was about 800 ft deep. The top of the inversion was around 2500 ft with a temperature of 31 C.

High confidence in vly and inland TAFs.

Moderate confidence in coastal TAFs through 17Z then good confidence. Flight Cat changes could be off by +/- 2 hours and VFR transition could be off by +/- 1 hour. There is a 25 percent chc of 1/4SM FG VV002 conds at sites with no dense fog fcst.

KLAX . Moderate confidence in TAF through 17Z, then good confidence. Low clouds could arrive as early as 07Z or as late as 10Z. There is a 30 percent chc of 3SM OVC004 conds and a 15 percent chc of 1/4SM FG VV002 conds 10Z-15Z. Lower confidence again after 18/05Z due to uncertainty in return of low clouds. Any east wind component will be 5 kt or less.

KBUR . High confidence in TAF.

MARINE. 17/317 AM.

In the outer waters, winds and seas are expected to remain below Small Craft Advisory (SCA) levels thru Thu morning. There is a 40% chance of SCA conds Thu afternoon. SCA conds are likely Thu night thru Fri night and again Sun, with a 30% chance Sat.

Across the inner waters north of Pt. Sal, SCA conds are not expected thru Thu morning. There is a 30% chance of SCA winds Thu afternoon/evening, and a 40% chance of SCA conds Fri afternoon and evening, SCA conds are not expected Sat thru Sun.

In the SBA Channel, there is a 30% chance of SCA level winds in western portions and near the islands during the late afternoon thru late evening hours today and Thu. Otherwise, SCA conds are not expected thru Sun.

In the southern inner waters, SCA conds are not expected thru Sun.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Heat Advisory in effect until 8 PM PDT this evening for zones 344-345. (See LAXNPWLOX). PZ . NONE.
