2018 California/Southwest Weather Thread

[Anti Marine Layer]

Only partly cloudy this morning, although it was overcast when I went to bed last night. Marine layer did deepen, but offshore flow must already be taking effect.

[Dan the Weatherman]

Still in CA for now, but heading to Eugene on 11-2.

 

As is common in these sorts of setups with ridging at the upper levels and a very weak offshore gradient at the surface, I recorded some of the warmest overnight lows in the country with 64 degrees last night and 68 the night before.

 

You must have some localized downslope flow in your area being next to the foothills that help to keep minimums up in your area.

Very hazy and humid with no sign of offshore flow this evening.

Here's a graph of the daylight gain/loss for Fullerton, CA.

 

 

Note that due the Equation of Time, which is the difference between mean solar time (as shown by clocks) and apparent solar time (indicated by sundials), we lose a lot more daylight in the afternoons than the mornings right after the Fall Equinox. The Equation of Time has its minimum value around November 3. This is the earliest solar noon of the year - about 16.5 minutes before 1200 UTC in Greenwich, England. By mid December, solar noon is getting almost 30 seconds later each day. The Equation of Time has its maximum value around February 11. This is the latest solar noon of the year - about 14.25 minutes after 1200 UTC in Greenwich, England.

 

We are currently nearing the November 3 minimum of the Equation of Time, at which point the morning and afternoon loss/gain are equal (red and blue lines intersect). After November 3, we lose more daylight in mornings than the afternoons.

 

For Fullerton, the earliest sunset of the year is where the red line intersects 0 minutes on the Y axis. This happens around December 4. The December Solstice is where the black line intersects 0 minutes on the Y axis. The latest sunrise of the year is where the blue line intersects 0 minutes on the Y axis. This happens around January 7. Note that we are referring to the earliest sunset and latest sunrise in UTC time. Currently,  we have later sunrises than on January 7 now with Daylight Saving Time still in effect.

 

Finally notice that amount of morning daylight loss increases each day after the Fall Equinox until leveling off in mid November. It is not until mid December the amount of morning daylight loss is the same as around the equinox.

As a cruel Halloween prank, the morning starts off foggy, when we are supposed to be getting offshore flow.

[Anti Marine Layer]

They forgot to post a Dense Fog Advisory.

[Jesse]

Looks like I'm getting out of town just in time for another week or two of very warm, dry weather. No rain anywhere in California on the GFS all the way out to 384 hours.

I heard there was some pretty cruel fog this morning. Probably almost felt like summer was over for a few hours.

[Anti Marine Layer]

No strong winds here today, but this afternoon was much warmer than yesterday afternoon. Sunset is becomingly ridiculously early, even with Daylight Saving Time still in effect, but it's fun to see the long shadows when I walk my dog after work.

  010300Z...Coast/Valleys/Mountains....Spooky FEW-SCT clouds with    bases 25000 ft MSL will prevail through this Halloween evening.    Pockets of LLWS possible S/SW of the mountains. Ghostly low clouds   are not expected to move into coastal TAF sites tonight or    Thursday morning. High clouds with bases 25000 ft MSL continue    into the morning with unrestricted vis.

Fog and haze are gone this morning, but we are off to a chilly start. Used the heat for the first time this morning. Welcome to November.

[Anti Marine Layer]

High clouds have thickened up without much effect on temperatures.

[Anti Marine Layer]

It's hot today, but nothing unusual for early November.

[Anti Marine Layer]

We have Thunder98 and Dan the Weatherman, but they don't post very much.

[Anti Marine Layer]

Another nice day here, which means not much to say.

[Thunder98]

What happened to Happ?

What happened to Happ?

 

Seems he was banned for his comments in Politics.

[Anti Marine Layer]

The early darkness is annoying, but sunset will only get about 12 1/2 minutes earlier. No pretty cirrus clouds tonight.

[Dan the Weatherman]

We have Thunder98 and Dan the Weatherman, but they don't post very much.

 

I haven't posted very much because there simply hasn't been much going on in the weather. I also post on Weather West and sometimes forget to post over here. I will try to remember to post more over here once the weather pattern finally becomes more active.

[Anti Marine Layer]

Another warm day where it will be cool by sunset

[Anti Marine Layer]

Big fire in Norcal. Not good news. I'm in Scottsdale for our company's annual conference. At least there were some flat cumulus clouds this afternoon.

[Anti Marine Layer]

A bit breezy tonight in Scottsdale. Desert winds usually pick up after sunset.

 

I hear there's Santa Anas back there. Hope not to fly back seeing towers of smoke tomorrow.

[TT-SEA]

Seems like we both picked a good time to be out of California.

 

What business are you in?

Could not be more beautiful in Orange County today!

I am in Edupoint Educational Systems. We develop student information system software for school districts across the nation. I am one of their best developers.

[Anti Marine Layer]

Sky has become smoky, but at least there's no smell.

[Anti Marine Layer]

Onshore flow brought a smoke layer instead of a marine layer.

Gorgeous sunset!

 

[Anti Marine Layer]

No wind here so far. Just another chilly morning that should become a warm afternoon.

[Thunder98]

It's going to be cold tonight!

 

[TT-SEA]

Newport coast is just gorgeous... looks like Italy.

 

[Anti Marine Layer]

What? Fog and drizzle in Lompoc this morning with a trace amount of rain.

[Anti Marine Layer]

Most of the country is frigid, while we have our usual Santa Ana winds and fires.

Even Brownsville, TX is in the low 60s, and they are about as far south as Miami.

It's perfection here!

Beautifully clear morning again in Newport Beach...

 

[Anti Marine Layer]

Days are warm, but night comes early, so I need to take walks during lunch to enjoy it.

 

Sunset today is slightly earlier than Christmas. Next week sunsets become earlier than Winter Solstice.

[Anti Marine Layer]

Maybe some rain next week, but for now it's just pathetically early sunsets and occasional periods of thick high clouds.

The sunset has been the same at this time of year all your life. Still beautiful down there.

Rain would be much more beautiful for them at this point.
