Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1059 AM PDT Sat Jul 24 2021

SYNOPSIS. 24/752 AM.

High pressure aloft will weaken through Monday leading to a general cooling trend, but increasing monsoonal moisture will bring muggy conditions. Showers or thunderstorms will be possible Sunday night through Tuesday, especially Monday when any area could see moderate to heavy showers. A small warming trend will follow Tuesday and Wednesday with little change to follow through the rest of the week.

SHORT TERM (TDY-MON). 24/756 AM.

***UPDATE***

The forecast is on target for today and no updates will be needed. The feature that some models were projecting yesterday for tonight is looking less concerning for any rain or thunderstorms. Forecast challenge for today remains the rare rain and thunderstorm chances for Sunday night through Monday. Everything still looks favorable widespread hit and miss showers, some of which could be moderate to heavy.

***From Previous Discussion***

Not much to talk about today. The marine layer is 15 ft deep and is being pushed ashore by moderate onshore flow to the north and the the east. Varying amounts of debris clouds advecting over from the TSTMs over AZ will make skies partly cloudy at times. The onshore flow to the east will increase this afternoon and some west facing beaches will not clear. The clouds, onshore flow and lower hgts will all combine to knock 3 to 6 degrees off of the max temps which will end up 2 to 4 degrees blo normal.

Not much change on Sunday - there will be a mix of marine layer clouds and mid level debris clouds milling about. Max temps will be similar to todays. To the east, however, the upper level pattern will be changing and setting the stage for an interesting 48 hour period. An upper low will move to the west and undercut the upper high near UT. The two systems will do a slow dance with the upper low moving to the SW and the upper high moving to the NE.

By Sunday evening a deep column of moisture will move into the area through the channel between the upper high and low. Skies will become mostly cloudy and a weak lobe of PVA rotating around the upper low will interact with the increased moisture over LA county to produce a slight chc of showers/TSTMs there.

The upper low and high will continue their respective journeys and by late Monday morning will be to the SW and NE of Srn CA. Moist southerly flow will set up over the area and PWATs are forecast to rise to between 1.5 and 2.0 inches. The upper low will rotate an easterly wave through this moisture column and will bring a chance of showers and slight chc of TSTMs to LA county on Monday with the best chc during the afternoon. A slight chc of showers/TSTMs will extend all the way to eastern SBA county in the afternoon. Due to the amount of available moisture heavy showers will be possible and will have to monitor all of Monday's convective activity for flash flooding potential esp over the mtns. Rainfall amount will be highly variable with this system since it will be composed of hit and miss convection.

All of the clouds and lowering hgts will make Monday the coolest day of the next 7 by far with most max temps 6 to 12 degrees blo normal and up to 18 degrees blo normal in the Antelope Vly.

The easterly wave moves further north on Monday evening and this will shift the threat of showers/TSTMs to the northern portions of the counties and including the interior of SLO county.

LONG TERM (TUE-FRI). 24/343 AM.

Things will settle down on Tuesday. A morning marine layer stratus deck is forecast for all of the coasts due to the onshore flow but would not be surprised if the inversion is still too mixed out for stratus to form. Otherwise, there should be enough debris clouds around to call it a partly cloudy day. There will also be enough residual moisture to allow for a slight chc of afternoon convection across the LA/VTA mtns and the Antelope Vly. Hgts will increase as the low exits but more importantly there will be much more sunshine and max temps will leap 6 to 12 degrees.

Things return to normal for the Wed through Fri period as a large upper high builds and across the entire western half of the CONUS. There will be onshore flow through the period and with it a night through morning low cloud pattern across the coasts. Two days of warming Wed and Thu will bring max temps 2 to 5 degrees above normal by Thursday. The max temps will then change little on Friday.

AVIATION. 24/1758Z.

At 1714Z at KLAX, the marine layer was 2000 feet deep. The top of the inversion was at 3200 feet with a temperature of 24 C.

Good confidence in TAFs for KPRB, KPMD and KWJF. Low confidence elsewhere for mainly the morning to early afternoon hours today.

Once the low clouds finally get dispersed from the coastal/valley sites the confidence levels are expected to improve. However, the first couple hours of the 18z TAFs could see a bit of delay in expected clearing times for a few locations due to stubborn marine clouds. Isolated showers are possible late in the day into Sunday.

KLAX . Moderate confidence in 18z TAF. VFR transition may be as late as 20Z. There is a 30 percent chance of VFR conditions through the period after marine clouds clear today. Good confidence that there will be no easterly wind component greater than 3 kt. Isolated showers are possible.

KBUR . Moderate confidence in 18z TAF. There is a 30 percent chance of VFR conditions through the period.

MARINE. 24/943 AM.

Not expecting any Small Craft Advisories (SCA) across the coastal waters through at least next Wednesday.

Patchy fog will continue into next week. The poorest visibility and most widely spread conditions will occur in the overnight and morning hours.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

.HAZARD POTENTIAL OUTLOOK (MON-FRI).

Monsoonal showers and thunderstorms are possible between Monday and Tuesday. Any storms will be capable of producing dangerous lightning and locally heavy showers impacting travel. There is a slight concern for flash flooding.
