2022-2023 California and Southwest Weather Thread

[Minny_Weather]

Once again, a cell has popped up a few miles south of me.

It's a curse wherever I go, man.

Looks like a typo! Maybe they were thinking of "overcast" when they were going to type "coast".

Dark and cloudy here again but it doesn't quite look like we're going to get lit up in the ECZ like yesterday. Riverside-San Bernardino looks a lot more active this evening.

[Anti Marine Layer]

The fun stuff stayed further inland.

[Thunder98]

High today was 77F. Coolest high in over 10 days.

[Anti Marine Layer]

Not quite as humid tonight.

If I had to guess I'd say I got about 0.5" today. Not bad considering at one point it looked like I would be missed entirely. Probably squeezed about 1.5" or so out of Kay. Not a bad performance for a La Nina September.

[Anti Marine Layer]

Yesterday was our last day in 2022 of the sun reaching more than 60 degrees above the horizon. 

[Pn1ct0g3n]

It’s quite wild to see some far interior areas swing from record heat to record cool in the space of a week, but this is the 2020s — nothing makes sense anymore!

Autumnal equinox is just around the corner. Will we get plunged into an early fall or will summer’s heat get a second wind? To be continued!

[Thunder98]

Only 68F right now. Went from above to below real fast

[Thunder98]

Seeing NW winds at around 20 MPH, windiest day in 2 weeks.

[Thunder98]

This weekend is looking very nice and fall like.

 

 

[Pn1ct0g3n]

Yow, those lows fell off a cliff. Now they expect troughing to continue into next week. Possibly catalyzing the onset of fall. Conversely the eastern half of the country gets to be unseasonably warm now.
 

Low clouds are already trying to move in here after a very remarkable 2 week absence. 

[Anti Marine Layer]

Reverse clearing today.

[Thunder98]

High today was 70F, below avg

[Thunder98]

Woah, there's now a chance of showers on Monday now! Fall is here! 

 

 

[Reg]

Night time temperatures still way above average, even as days have cooled off to mid-80s. About half way through September and the month is currently about nine degrees warmer than normal. How far that will cool down by the end of the month is anyone's guess. Unless we see a sharp cold spell later this month, September is likely to end much at least several degrees warmer than normal here.

At my weather station, September 1-13:

Average high 98.7

Average low 73.2

 

[Thunder98]

We will see a cold front this weekend!
 

 

[Anti Marine Layer]

Marine layer is back and quite deep.

[Thunder98]

[Pn1ct0g3n]

Wow! Early season event. And I thought the one we had in mid-October last year was unusual. The locals must be scrambling for their Uggs and pumpkin spices at the news.
 

Yup, I woke up to the gloom this morning for the first time in a while. Our ocean temps are in peril with this pattern too. Depending on how they react and what comes next, this could well be a ‘false fall.’

[Pn1ct0g3n]

There is little difference between the coast and interior temps today. Reg ought to be celebrating the mid-70s in Murrieta today!

[Anti Marine Layer]

San Diego having trouble clearing

[Anti Marine Layer]

There are 2 inversions today!

It reached 83 here today but no complaints here, felt amazing. Low was 62 this morning, coolest in two months.

[Anti Marine Layer]

Quite breezy today. It was a cool breeze too.

[Anti Marine Layer]

Low clouds have gathered along the coast.

[Thunder98]

Today was windy. High was 72F

[Anti Marine Layer]

Marine layer is deep and looks to stay that way for a while. 

[Anti Marine Layer]

No more double inversion. Kay is a distant memory.

[Pn1ct0g3n]

Felt a chill in the morning air I haven’t experienced since before the heatwave. And I’d almost forgotten that this cool breeze was the norm.

After a few days of boredom, we get the chance for weekend rain. The NWS has gotten a bit more bullish on the cutoff low scenario…but as we all know, weatherman’s woe.

[Reg]

Noon and only 74F. I don't think I've seen that here since May.

[Pn1ct0g3n]

It’s actually warmer in the coastal areas than some inland spots today. 76 now; Torrance hit 80 earlier. You can thank the low pressure and lack of a well developed inversion for that.

A week from now, they’re saying it could warm up again, making this period a ‘false fall’.

[Thunder98]

Could see close to a half inch of rain Monday! 
 

 

[Minny_Weather]

Will very likely struggle to reach 80 a couple days next week. Average highs are still in the low-mid 90s.

[Thunder98]

72F, it was windy again, felt like spring

[Anti Marine Layer]

Nice day today. 

[Anti Marine Layer]

One week until Fall Equinox.
