Happy longest day of the year!

[Pn1ct0g3n]

Burnoff started much earlier today but still didn’t clear the beaches. The heatwave continues in the deserts but it’s pretty seasonable everywhere else. 

[Anti Marine Layer]

June Gloom is reaching further inland in parts of Baja California.

[Anti Marine Layer]

This year's Summer Solstice could end up being cooler than last year's Winter Solstice.

12/21/20  FUL  :      FULLERTON AIRPORT   96 :   86 /  46 /  0.00 /

Right now it's only 73 in Fullerton.

[Pn1ct0g3n]

Definitely a stronger onshore flow. Winnetka and Woodland Hills barely squeaked to 90. Edinburgh had a warmer high than Carpinteria!

Yes. Even here inland, June 2003 remains the coolest June on record. But it was followed by one of the hottest summers we've ever had, which I still remember even though I was in middle school at the time. July-October 2003 was hell.

[Pn1ct0g3n]

Clouds broke enough to enjoy a walk at sunset. Nights are chilly again—next week will have several lows dipping below 60, which is starting to remind me of last year…

[Anti Marine Layer]

Low clouds tried to push in early, but then they decided not to.

[Anti Marine Layer]

First full day of summer today.

[Thunder98]

This is one strange marine layer map.

 

[Pn1ct0g3n]

Today could be the first time since Thursday that the PV-LAX sub-microclimate fully clears out. A little less heat in the deserts can do a lot to help the beaches clear.

[Pn1ct0g3n]

Warming up in the Bight!!

I’m not celebrating prematurely—we saw a similar trend at the same time last year and then the pattern slammed back to northwesterly flow that continued all of July and into August, and at one point SD’s water temp dropped to 55F (!!)

Why would you want things to get even warmer after all of the drought and fire issues your state has seen in recent years? Aqueducts running dry, people losing their homes and lives, millions of acres of trees dying in the Sierras.

It’s like there’s four or five Mr. Marine layers posting over here now.

I’m case you’re wondering — no I’m not MML’s alt. I simply share many views with him. Drought and fire are terrible things, that I won’t deny. But they are also part of the ecosystem. But I don’t mind a little rain or fog here and there. I just feel that summer should be…summer, and it’s one of the few downsides to living here besides taxes and politics.

Then why does it matter if the balance swings toward one or the other? Long term, life adapts, and you can like any kind of weather you want. I don’t judge you for your love of rain and fog. It’s all a matter of preference.

It’s been going in one direction (hotter and hotter) for a really long time now, and probably will for the rest of our lives. I just can’t see the enjoyment in something so destructive and life destroying but each to their own I guess.

Most of the places where the fires happened are far away from the marine influence.

Also freezing ocean temperatures lower the dew points and decrease the likelihood of monsoonal thunderstorms which could give some beneficial rain.

I'm sure they were counting their blessings. I mean, losing your home AND having to deal with low clouds??

[Pn1ct0g3n]

Ended up being a pretty pleasant first full day of summer. Seasonable and comfortable.

Cooler ocean temperatures also result in stronger sea breezes, which actually increases the fire risk inland.

[Reg]

Had a low of 60F this morning, the coolest low here in a week. But this afternoon was warmer than yesterday, with a high of 94F here in Murrieta (versus yesterday's 90F).

[Pn1ct0g3n]

Might need a hotter shower tomorrow: humidity is down = cooler low ahead. Much breezier than yesterday too. If cool nights get you down, just remember that you get more deep slow wave sleep when it’s cooler. 

[Pn1ct0g3n]

I’m a sucker for a good sunset. Looking NW from my house. Check out the visibility—those are the Santa Monica Mountains in the background!

[Anti Marine Layer]

Paso Robles only expecting a high of 74 today.

[Pn1ct0g3n]

Today is supposed to be the start of the big cooling trend and I believe it. It’s already blowing pretty good and the sea breeze never really died down last night. MB only expecting a high of 66 on Friday. It’s also blowing out of the NW in SD so it’s not eddy winds. (Credit to MML for teaching me this detail)

By the weekend they’re predicting a return to more July-like conditions.

[Pn1ct0g3n]

Not likely we reach 70 for a few days to come. Long Beach once again back to its typical conditions of being several degrees warmer than us, since the southerly component to the winds is gone.

[Pn1ct0g3n]

Satellite shows a scraggly stratus field and what looks like a gulf surge to the southeast, and an eddy (?) spinning off the Central Coast. Still learning how to read these.

[Anti Marine Layer]

I think it's an upper low spinning off the coast.

Explains why it’s so breezy here and why some weak precip is showing up on radar to the south and east. Saw something moving through SD and Imperial Counties now. Might be getting pulled into our area by the flow around the low.

[Anti Marine Layer]

Thick high clouds have moved in.

[Reg]

Mr Marine Layer you seem to have made a friend on here.

Strange weather today, mostly cloudy skies all around Southern California. Temp hovering around 90F.

[Pn1ct0g3n]

It is kinda weird. Most of the low clouds blew out and I can see the high stuff now. Winds still howling off the Pacific locally, but beaches farther south are enjoying gentler breezes.

[AquariusRadar]

Checkout those light showers south of Phoenix and SD area. Has the monsoon started?

Looked like it on the satellite, and the middle/high clouds have shown up here too. Still far too much onshore flow to see a slopover storm. And lookit dem puffs!

 

75 in Paso Robles right now, and it’s 6PM. I wonder how much they beat their forecast high of 74 then.

[AquariusRadar]

Why would Diamond Valley Lake be able to provide municipal water for years of drought if the water source for the lake is tapped out by drought? This article makes it seem Southern California will not have a problem with years of drought.

Whistling past the graveyard?

[Pn1ct0g3n]

Another pretty sunset. Check out the virga from that one cloud! My dinky smartphone camera doesn’t do sunsets justice.

Paso high today was 83F. 9 degrees warmern than expected
