[Anti Marine Layer]

Looks like some nice stuff happening in San Diego County.

The southern Santa Monica Bay was literally the last place to clear south of Pt.C today.

Flash flood warnings in Riverside County too. Rain appears to have reached the coast in some places!

Encountered rain on the 15 nearby just a few hours ago.

The San Diego Coast, Oxnard Plains and the Central Coast are socked in this morning.

The cloud gods gave us a pleasant morning here. It’s a bit counterintuitive but beach clearing is easier with a medium marine layer than a really shallow one (which classically leads to heatwave fog hugging the coast).

[Pn1ct0g3n]

Some gunk creeping into the SMB from the south.   Eddy is back, taking the edge off inland temps.

[Thunder98]

The first half of September is looking very uneventful heatwise. Sounds a lot like September 2016...

 

[Pn1ct0g3n]

And more troughing, which means more cooling, which means more NWly winds, which means cooler water, which means more clouds, which means yet more cooling.

72 for a high today when historically we should expect 77. Is this our future, an outlier in the global warming world?

[Pn1ct0g3n]

Meanwhile, SD/northern Baja area residents are getting some juicy air again. Mixing out the marine layer down there.

This will aid firefighting efforts for the Chaparral Fire. Much cooler today here.

The Joshua Trees get a little sprinkle. Hurray. Not to be political but I agree with the candidates' goofy aqueduct idea in this article. not so goofy idea

https://news.yahoo.com/column-building-pipeline-mississippi-idea-120038483.html?fr=sycsrp_catchall.

If we can spend trillions and trillions on military hardware-that we frequently abandon in far flung places-we can build aqueducts that make our state self sustaining. As a state and country, we need to put our big boy pants on, get the shovels out, and start digging.

[Pn1ct0g3n]

Widespread moisture moving in. It rained here for about 5 minutes. A pop up storm would be nice.

[Pn1ct0g3n]

Instability helped mix things out here, but for areas outside the monsoon plume, the marine layer is holding fast.

Cool even inland — low 70s in Temecula.

[AquariusRadar]

If the aqueduct idea seems goofy, here is an alternative: building more reservoirsAnother reservoir

The problem we have is getting water to store in the reservoir. We have plenty of empty reservoirs.

Added later: others agree that maybe aqueducts may be an answerLA Times Letters to editor

A mix of scattered marine layer stratus clouds and mid level monsoonal debris clouds this afternoon.

 

 

 

[Thunder98]

Drizzly this morning, very May like.

[Anti Marine Layer]

Meteorological fall is here.

[Thunder98]

Is this May or September? The Marine Layer stratus goes past the Kern County line and the into the Cuyama Valley!

 

[Anti Marine Layer]

Not quite the drizzlefest of 2 weekends ago, but still a very deep marine layer to start Fogtember.

[Pn1ct0g3n]

Septembrrr?

Eddy be spinnin’.

[Pn1ct0g3n]

Reverse clearing too.

[Anti Marine Layer]

Not even Inland Empire clearing out yet.

[Anti Marine Layer]

Who's ready for s'more record low highs?

[Anti Marine Layer]

[Anti Marine Layer]

Deep marine layers create warmer beach weather and cooler inland weather.

[Thunder98]

Meteorological Summer was very average and super boring this year for the Santa Maria area. Only 1 day above 90F and 6 days above 80F. Really pathetic. Last Summer, there were 3 days above 90F and 15 days above 80F.

Especially deep marine layers created by an eddy pulling up warmer water. But if the eddy is too strong everything will be socked in. Funny how that works. Today turned out warmer than any of the last 4 days once the sun came out.

[Anti Marine Layer]

Sun might be coming out.

[Anti Marine Layer]

Feels like fall again. How much longer till it snows in Omaha?

[Thunder98]

Despite, the deep marine layer this morning, which produced 0.01" of light drizzly rain, it went up to 75F today!

[Pn1ct0g3n]

Echoing Thunder98 for how it felt here in the South Bay:

2021 was an odd beast of a meteorological summer. Very mild, near to a bit below average with no major heatwaves. Very 2008-like. There were even some periods of near record coolness across America’s southern tier while heatwaves raged up north. 

The monsoon was very active but unlike the other big monsoon years of the 2010s, it remained cool with dews rarely exceeding 65 and almost no instability reached the coast. Probably because the ocean was cooler than those years, so onshore flow was nearly continuous and convection almost impossible. Whenever the ocean tried to warm up, a northwest wind event soon knocked it back down. 

It’s not over yet! September is the start of meteorological fall, but it’s really a late summer month most years here. Let’s get a tropical remnant up here to send it off.

[Anti Marine Layer]

Low clouds refused to socially distance today and masked out the sun all day. Still reached the mid 70s, though.

September 1 update for my weather station:

[Anti Marine Layer]

70 this morning in Fullerton. How was Malibu 59 on Sunday?

[Anti Marine Layer]

It's even thicker this morning than yesterday.

[Pn1ct0g3n]

Cleared out here, around 1:30pm. In fact the whole coast from Carmel southward has cleared save for a patch near Point Arguello. That’s above and beyond for 2021.

[Pn1ct0g3n]

Much breezier today for some reason. 

[Thunder98]

Interestingly Santa Maria had the lowest extreme low out of all the cities last month at 50F.

 

[Pn1ct0g3n]

Overall remarkably close to the 1991-2020 normals. Global warming my foot.
