2019 California and Southwest Weather Discussion Thread

[Anti Marine Layer]

It gets dark faster at this time of the year than any other time of the year except for the spring equinox, where it gets dark at at the same rate as today. Also we have a greater rate of daylight loss per day now than any other time of the year.

 

Anyway, it was a nice final evening of astronomical summer.

[Anti Marine Layer]

Low clouds should make a recovery tonight.

[Reg]

Very warm tonight.

[Anti Marine Layer]

Fall is off to a cloudy start.

[Anti Marine Layer]

Rather slow burnoff process this morning.

[Jesse]

Last full day of summer today with Fall Equinox at 12:50 AM tomorrow.

Summer ended 23 days ago.

[Reg]

Summer ended 23 days ago.

Meteorological vs. astronomical debate. Due to the persistence of summer-like weather in our part of the country well into mid-to-late September during most years, I'm siding with Mr Marine Layer here. In some years, September was the warmest month of the year here.

 

Offshore flow to spike temperatures tomorrow.

Yeah but adjusting the official start of fall and having it tailored to the seasonal lag of each particular region would get pretty confusing. I find it's just easier to use the meteorological definition across the board. Especially since this is a meteorology forum

Even the forecast discussion wished a happy first day of fall this morning.

[Anti Marine Layer]

Should be lots of ups and downs in the weather over the upcoming week.

[Anti Marine Layer]

0.70" today in Flagstaff. They could make up for their dry monsoon over the next few days. Snow was also reported on the highest Arizona peaks.

[Anti Marine Layer]

Fastest change in solar declination does not happen until a few days after the Fall Equinox becuase the orbit of the earth is an ellipse with its fastest speed in January. This also makes the astronomical fall and winter a bit shorter than the astronomical spring and summer in the Northern Hemisphere.

[Anti Marine Layer]

Phoenix is down to 70 F with all the thunder and rain they are getting.

[Thunder98]

The stratus fog moved unexpectedly in at around 6:30pm and we are expected to reach 90F tomorrow. Where is the offshore flow?

[Anti Marine Layer]

Still overcast this morning as the offshore flow is slow to materialize.

[Anti Marine Layer]

Our morning is 41 seconds shorter than yesterday morning and our evening is 83 seconds shorter than yesterday evening.

[Thunder98]

89F with 10 mph NNE offshore winds, big turnaround from this morning and yesterday evening.

 

 

[Thunder98]

It's 98F now, about 8 degrees hotter than what was forecasted today. 

[Thunder98]

The 5 minute unofficial observations says it's 100F!

 

[Anti Marine Layer]

Only upper 80s here so far.

[Anti Marine Layer]

NOAA sites are currently down.

[Jesse]

Even the forecast discussion wished a happy first day of fall this morning.

Weird right? It’s like the Catholic Church making a happy Kwanzaa post.

[Anti Marine Layer]

Haze indicates that Santa Ana winds were not able to reach the coast here.

[Thunder98]

It appears that the winds are shifting back to the North again as it's remaining steady around 89F with a North-Northwest wind now. Earlier it was a West-Northwest wind.

 

[Thunder98]

The official high today in Santa Maria was 100F, the last time it reached 100F or more was on October 24th, 2017 when it reached 102F.

[Anti Marine Layer]

Should be the last hot day near the coast for quite a while.

[Anti Marine Layer]

Warm evening with it quickly getting dark.

[Anti Marine Layer]

Eddy should be spinning up soon.

[Anti Marine Layer]

Looks like some dense fog to start the day here today.

[Anti Marine Layer]

Satellite links are down today. Lots of problems with the NOAA websites lately.

[Reg]

Lot of high clouds today, but not too warm like yesterday.

[Reg]

Getting cloudy and windy here.

[Anti Marine Layer]

Interesting start to the fall season, astronomical fall that is.

[Thunder98]

Fog is moving in after a high of 88F

[Reg]

Good to see you and Jesse worked it out 

 

High clouds still here but lower, ground-level fog is visible hovering over the Santa Ana Mountains just to our west.

[Anti Marine Layer]

Technically fall began on June 21, when the days began to get shorter.

[Anti Marine Layer]

Looks like Palm Springs got a nice dust storm.

[Anti Marine Layer]

Looks like thunderstorm outflow boundaries from inland pushing towards the coast are in a battle with the eddy and marine layer tonight. Low clouds seem to have been disrupted for now.

[Anti Marine Layer]

Last day here with more than 12 hours of daylight in 2019.

[Anti Marine Layer]

Looks like it's already drizzling this morning.
