2020/2021 California and Southwest Weather Discussion Thread

[Mr Marine Layer]

Better sunshine on Saddleback today at 5 PM.

 

[Mr Marine Layer]

Lots of marine layer haze in the above photo and possibly some low clouds on the horizon as well.

[Mr Marine Layer]

Mostly clear and mostly chilly today.

[Mr Marine Layer]

Air quality not looking to be that great.

[Reg]

Air quality not looking to be that great.

 

I noticed that today as well.

 

NWS has upped their precipitation total predictions for Thursday. This morning they had my area at 0.1-0.25", now it's 0.25-0.50" for Thursday's cold front. Snow level could be around 3500 feet.

[Mr Marine Layer]

While PNW gets snow, we get another cool, partly cloudy day here with nothing to talk about.

[Mr Marine Layer]

Haze will stick around until we can get some rain to wash it out or some offshore winds to blow it out.

[Omegaraptor]

While PNW gets snow, we get another cool, partly cloudy day here with nothing to talk about.

 

No snow in Portland, but then again Portland is pretty much CA anyway nowadays.

[Reg]

NWS adjusted precipitation totals down again.

[Mr Marine Layer]

Getting tired of this stagnant haze/inversion pattern.

[Mr Marine Layer]

Saddleback Mountain is no longer visible here.

[Reg]

Saddleback Mountain is no longer visible here.

 

It was never visible from this side of the mountains today.

[Reg]

NWS adjusted totals upward, again.

[Mr Marine Layer]

NWS adjusted totals upward, again.

Keeps going up and down.

[Reg]

Another day of mediocre air quality. At least it makes for an interesting view from higher elevations.

 

[Mr Marine Layer]

Hope the rain will improve our air quality. It's been a stagnant onshore flow for a week now, which is quite unusual for this time of year.

[Mr Marine Layer]

For the 16th time in the last 17 days, the sunrise is at 6:55 AM. In the same time, the sunset has changed from 4:52 PM to 5:06 PM. Sunrise will finally be 6:54 AM tomorrow, but that's still later than the Winter Solstice.

 

Looks cloudy this morning so hopefully we can get more than just some sprinkles or drizzle from it.

[Mr Marine Layer]

It's another hazy morning with random low clouds. Starting to look like Beijing or Mexico City here regarding the haze.

There's been quite a bit of that these past few days.

Meanwhile in my area, the air quality has remained excellent.

 

[Reg]

Somehow got worse over the last 2 hours. 

 

[Mr Marine Layer]

It's chilly out there today.

[Reg]

Low clouds and gusty winds just appeared out of nowhere here.

[Mr Marine Layer]

We have had low clouds most of the day.

[Mr Marine Layer]

Rain looks like it will be an overnight event.

[Reg]

Front already weakening near Point Conception on radar.

[Thunder98]

Now at 0.51'', overachiving even my prediction. The heaviest rain occurred during the 16:00 (4pm) hour.

 

 

[Mr Marine Layer]

Looks like the front is weakening significantly on its way down here.

[Mr Marine Layer]

Light rain starting to fall.

[Reg]

Not related to the current "storm", but something just occurred to me - the NOAA and NWS use 30 year averages, which they update every ten years to calculate average temperatures/precipitation for a given location. For years now I had gotten used to seeing "1981-2010 averages" on their websites and data pages, and before that I remember seeing "1971-2000 averages". Some old pages still even have "1961-1990 averages" if you can spot them. But now, or probably starting next year, we'll start seeing "1991-2020 averages" in their data.

[Reg]

Light rain started at exactly midnight here. 0.01"

[Reg]

0.07", light rain continuing even though it has all disappeared from doppler radar.

[Mr Marine Layer]

The mountains are visible again.

[Thunder98]

Finished 0.52" yesterday, which was almost spot on from my 0.50" prediction.

[Reg]

Ended with 0.07". I guess I can't complain, but looking forward to more rain eventually.

[Omegaraptor]

Meanwhile in my area, the air quality has remained excellent.

What’s going on around Mono Lake?

[Mr Marine Layer]

What’s going on around Mono Lake?

Must have had something to do with the bad diarrhea I had once when I was there.

[Mr Marine Layer]

Despite the much later sunsets, now a few minutes after 5 PM, there are still idiots driving around with their high beams on at 4:45 PM.

[Reg]

Lot of high clouds today. Still a slight chance of showers for Tuesday.

[Reg]

Offshore winds just picked up here, spiking temps and plummeting humidity.

[Mr Marine Layer]

Thick high clouds have moved in but it got pretty warm before that, and still is quite warm, though it probably won't stay that way for too long.

[Reg]

Completely cloudy now. And to think it was 77F earlier. Still a dusting of snow atop Saddleback as I was driving back from L.A. this afternoon.

[Reg]

High clouds are preventing temperatures from cooling properly tonight. 8:23 PM and only a stagnant 60F wouldn't be unusual for May, but very rare in January.

[Mr Marine Layer]

Low clouds moving in under the high clouds on this 1/20/2020.

[Mr Marine Layer]

Lots of high clouds and no more low clouds.

[Thunder98]

I hope this thing makes it to the coast and brings a couple hundredths. Knowing that most of the radar returns is Virga.

 

 

[Mr Marine Layer]

High clouds thinned out for some time allowing low clouds to form, but low clouds disappeared again as high clouds thickened back up.

[Reg]

Some measurable light rain in Ventura County as well as southern San Diego County near the border, and even a few heavy patches in northern Baja.

[Reg]

0.04" here, rain started out of nowhere 20 minutes ago.

[Mr Marine Layer]

Looks like we had some measurable rain from this "storm".
