2020 - 2021 California and Southwest Weather Discussion Thread

Temps for the coming days in Anaheim (my preferred semi coastal ref point to track, as it’s outside the Los Angeles UHI and beaches are too fickle) were adjusted upward. Valleys too. High 97F and low 70F for Woodland Hills for the 29th!

Looks like the warmup will kick in with my birthday on the 27th. As for the immediate coast…I’ll believe it when I see it.

Nice clear skies and little wind this morning, though a wall of gunk has persisted just south of me and keeps trying to poke its head in, like a hungry cat. You can see it on the satellite curling up past PV. It’s a good day to hit the beach across most of the region!

[Anti Marine Layer]

Got a few raindrops earlier this morning.

[Pn1ct0g3n]

Looks pretty juicy out in the deserts, but little chance of straying this way.

[Pn1ct0g3n]

Air feels drier than before to me today and it’s REALLY breezy. When I got out of the pool I felt really chilled from slightly wet hair. Dew points are pretty low for late June. There may be monsoonal clouds above, but down at the surface it feels like late April but warmer.

Looked at the radar and there’s tons of action to the east, as soon as the monsoonal flow exits the stable marine air mass. A pop up shower just went through Pomona and the entire IE is lit up.

Came home from work just now to find that 0.02" had fallen at my house today, sometime in the morning. I verified it with my manual rain gauge which showed the same total. A wildfire near Pala in northern San Diego County is sending a ton of smoke up our way as well.

[Pn1ct0g3n]

A little late to capture it but that sunset was spectacular. Another evening with insane visibility for June so the reds and oranges really pop.

[Pn1ct0g3n]

Looks like that pesky northwesterly flow will continue today. NWS adjusted our temps down for the coming week, and all microclimates are looking to be near normal with nothing special.

Last year we had a lot more NW flow than normal, leading to No-sky July and even Fogust. Hoping we don’t get an encore of that.

Temps in my area were adjusted down too. At least we could see a robust monsoonal flow next week.

[Pn1ct0g3n]

Fingers crossed. I didn’t get much influence from the last monsoon event here as the onshore flow was too strong. There was a streak of years that remained unbroken from 2014 to 2019 where a thunderstorm closed a beach on LA’s Westside, sometime in mid July, until 2020’s Bummer Summer arrived. I wonder if that’ll happen again.

[Pn1ct0g3n]

As fairly normal conditions return down here, now it’s the PNW’s turn for a heatwave. Seattle and Portland could have all time records fall on the hottest day—the 27th.

[Reg]

Very different weather today compared to yesterday, mostly clear skies and otherwise quiet. Some cumulus forming over the mountains to the east, however.

Breezy today

Last few days it’s consistently gotten to 18mph each afternoon. Could be just my imagination but I feel like it’s windier here on average than it was many years ago.

[Anti Marine Layer]

Downtown LA only reached 74. Strong sea breeze, but at least no major June Gloom. 

[Thunder98]

The heat last week was a bust on the intermediate coast from Santa Barbara County to the Mexican border and next week looks like more like the status quo except for some potential monsoonal moisture.

Midweek we had about 3 days of solidly above average temperatures, but the latter half of the heatwave didn’t reach the coast here.

Still plenty of chilly water out there, and the wind events this week won’t help change that.

[Pn1ct0g3n]

Low clouds have mostly “played hooky” as MML puts it, enough to get a great view of the Strawberry Supermoon.

[Anti Marine Layer]

Geocolor is frozen in time. 

Apparently northwest flow has kept the low clouds out of Orange and Los Angeles counties this morning.

 

[Pn1ct0g3n]

Perfectly symmetric “stratocane” showing up on sat images, slowly rotating in the center of the Santa Monica Bay.

[Pn1ct0g3n]

There’s a massive cold anomaly in the eastern and central subtropical Pacific extending clear out to the vicinity of Hawaii and beyond. Leftovers from La Niña?

[Pn1ct0g3n]

Ended up being a pretty pleasant day. Temps near normal and not as windy.

And no thunderstorm clusters across the whole central Pacific ITCZ. Doesn't bode well for drought relief. Agree-looks like La Nina.

Drove through some areas of very dense fog on my way to work this morning.

[Pn1ct0g3n]

Water temps took a bit of a hit from the breezy week. The low off the coast through Thursday night must have contributed. 

[Pn1ct0g3n]

Sat feed: Mainly sunny here, but socked in from the OC coast clear down into Baja.

Update: by 1PM the Sepulveda Wall was trying to establish itself. Much of this week had a strange pattern where the southern Santa Monica Bay was sunnier than the northern part. Today we’re back to the typical pattern, which is the reverse of that. The stretch of coast from Hermosa to PV Estates is a particularly strong fog belt that is usually the first place to cloud over and the last to clear out locally.

[Reg]

Warmer here today, 96F.

[Anti Marine Layer]

Sea breeze is keeping the temperatures mild here, getting pretty strong at times. 

[Pn1ct0g3n]

Woodland Hills got to 97. They were saying tomorrow it could hit 100 again.

[Anti Marine Layer]

June Gloom has found a strange location tonight.

 

 

[Pn1ct0g3n]

Also check out that hole in the clouds several hundred miles out. It’s been there most of the day.

[Pn1ct0g3n]

Happy birthday to me. Looks like some gloom is joining the festivities. Satellite seems to be showing a weak eddy. Many beaches struggling to clear.

[Pn1ct0g3n]

Inland areas heat up, sun goes away at the coast. It’s funny how temps spiking inland can actually make beaches BELOW average.

 In places where the sun is out I can see some high cloud action again. 

[Pn1ct0g3n]

Dewpoints in low 60s again in most coastal and inner coastal areas, more in line with what you typically see this time of year. 

[Thunder98]

Shame that the coastal areas will not see any heat from heat wave impacting the west.

It always feels like a coin flip whether or not the beaches will warm proportionally, or get fogged in instead. 2017 had some crazy heatwaves that actually brought below average temps and dense fog to the immediate coast. Saw some of that last year too. Imagine 63 in Manhattan Beach and 110 in Woodland Hills, which might have been the most extreme microclimate day I’ve ever seen.

At least by August and September, the coastal areas should finally see some serious heat as the ssts are at there warmest and marine layer is more sporadic.

Even 2020 finally got there, sort of. We still had long runs of troughiness and gloom then. No-sky July turned into Fogust. I still feel kinda spoiled by the beachgoer’s dream summers of most of the 2010s.

[Anti Marine Layer]

Eddy seems to be back.
