2022-2023 California and Southwest Weather Thread

The pulse that hit T98 is still going strong, marching up the central coast through SLO and beyond. Might even make it to Monterey, or fire something off in the Central Valley.

Otherwise, little or no spillover west of the mountains.

High 77 here, though it’s crashed hard now that the breeze is whistling through my window screens.

Hope there's no dry lightning.

81F right now at KSMX. 7 degrees warmer than the forecasted high of 74! That impulse that brought some rain this morning disrupted the marine layer today.

[Pn1ct0g3n]

It reformed in due time here. Seriously, what is it with the Santa Monica Bay?

[Anti Marine Layer]

Warm night so far.

[Anti Marine Layer]

While much of the world sees record breaking heat, San Diego has yet to reach 80 this summer.

[Pn1ct0g3n]

Inversion still strong, so for the umpteenth time, don’t expect full clearing at the beaches. Already a spread of around 8 degrees between the exposed beaches and more sheltered ones.

No instability to mix out the marine layer locally = 10 degrees cooler at the immediate coast than yesterday. There’s some very juicy air residing over northern Mexico, but the flow is probably steering it well to the south and east.

[Pn1ct0g3n]

Well, the ocean has finally warmed up again. Big increase especially between 30N and 32N. Santa Monica Bay and VC coasts too. 

That said, they’re predicting a trough over the weekend that could knock it right back down in a flash.

[Pn1ct0g3n]

Made very little difference in the unrelenting gunk clinging to us. It wasted no time rushing back. 

[Pn1ct0g3n]

Meanwhile, in beautiful Japan they are blessed with this. This is at 4:44 AM in Nagoya, where my friend lives, mind you. Their high should be close to 90 with dews in the upper 70s. Perfection. The power of ocean currents.

[Anti Marine Layer]

Hot today away from the immediate coast.

[Reg]

99F about twenty minutes ago.

[Pn1ct0g3n]

Clearing ended up good compared to how it’s been most of the month. High at the coast 73, give or take a few depending on local topography. Reasonable for mid July, especially after what we’ve been going through.

[Reg]

Some clouds east of here again today, but nothing compared to yesterday.

[Thunder98]

79F today

[Anti Marine Layer]

Hot today.

What do gardeners, garbage trucks and carpet cleaners have in common?

They make too much noise.

[Reg]

Lot of high clouds arrived over here now.

Seems we both saw the same sunset

[Anti Marine Layer]

More high clouds this morning. 

[Pn1ct0g3n]

“While the [high and middle level] clouds look impressive on satellite…forecast stability values do not suggest a very unstable atmosphere.”

Translation: Nice backdrop but don’t expect any pop up showers or storms west of the mountains. More of the same today — should remain hot away from the coast, with onshore flow strong enough that some beaches may not clear. It’s another one of those mornings where it’s sunny and nice here, but the fog is lingering just off the coast and could blow back in any time.

[Anti Marine Layer]

The marine layer over the ocean is well developed. 

[Pn1ct0g3n]

It’s starting to make a push for the coast again but with the warmer SSTs it may not last as long.

[Anti Marine Layer]

Shadow of next door skyscraper is starting to creep over the fence now.

[Anti Marine Layer]

PNW could get a heat wave next week, but doesn't look like anything too spectacular down here. 

[Reg]

Not as warm today here, 94F compared to 97F this time yesterday.

And guess what? It got a few degrees warmer at the coast too. Feels like proper summer here, finally. It appears that our highs are inversely correlated.

[Pn1ct0g3n]

SD at 78F today. They may have broken 80 before the sea breeze kicked in.

[Anti Marine Layer]

Looks like San Diego made it to 81.

[Reg]

Looks like I called it way too soon. Temperature at 101F now and still climbing. This is the latest in the afternoon the temperature has peaked (or will peak) here since June 23 (during which our high was also 101F).

[Pn1ct0g3n]

Just south of me is looking juicy! I wouldn’t get my hopes up but maybe there’ll be a shower? Whatever it is, it’s coming this way.

July 20…That’s late! When’s the last time it took that long?

[Reg]

101F was the peak around the time of that post. Steep decline shortly after that.

Minute-by-minute temperature graph of my weather station over the past three days (including today through 5:30 PM). Note the typical temperature peaks in the afternoon between 1 and 3 PM. Today it happened after 4 PM, which is rather rare. Also worth mentioning that today was actually cooler around noon and the early afternoon than during the previous several days, but then it just kept getting warmer when the temperature would usually level off. Not sure what happened.

EDIT: Wind might have had something to do with it. Sea breezes were weaker today at my location  until just after 4 PM, finally kicking in right when the temperature turned around.

Don't think it happened until July 23 in 2019. Also, it says they only reached 80 today in the climate summary.

[Thunder98]

only 71F today

[Anti Marine Layer]

Clouds are headed our way.

[Anti Marine Layer]

Nothing amounted from the clouds.

[Anti Marine Layer]

ML has been disrupted for now.

[Pn1ct0g3n]

Gave us a pleasant sunny morning here
 

[Anti Marine Layer]

Onshore flow is expected to strengthen again.
