If we can't get rain or even clouds might as well go to the beach. Ed Joyce posted photo of Huntington Beach taken yesterday evening.

Nice recovery of dew points tonight as onshore gradients increase. Still warm today but tomorrow should be below 80F for the first day in a week.

GFS MOS takes Avalon from 64/57 tomorrow to 93/79 by early next week. Probably overdoing the downsloping signal for the minimums. Showing 104 for Fullerton and 102 for Long Beach. Record territory for so late in the fall.

October triple digit readings have occurred in 5 of the last 10 years. So it is not unheard of and never welcomed

San Diego reached 100 F on November 4, 2010 after one of their coldest summers on record.

It's getting a bit late to see 102-104 degree readings. It would be a first for the LBC this late into October.

I remember that ridge. Also brought the latest 100 to Long Beach, along with a bunch of monthly records here in the PNW.

 

You guys also had the heat wave in late Sep with the 113 in LA.

Drizzly light rain in Santa Maria

Received 0.03" of rain. More than I expected

[Thunder98]

It's drizzling again

It's drizzling again

 

Satellite shows clouds from what is left of a front moving toward Pt Conception w/ possible showers even further south later in the day. Marine layer is weak and scattered.

Records for the day and latest day in the year will likely occur it appears.

[Thunder98]

Feels and looks like fall today. It's chilly and about to become windy today.

Some better than predicted rain totals across Northern California [north of Monterey/ San Joaquin valley]

Looks like a good Santa Ana is getting ready to setup for the next 4 days.  Mon night into Tues looks like the best time frame.  NWS in San Diego is only thinking 40 mph gust as the moment (in cajon), which looks okay with the pressure gradient that will be setting up.  Models are a little bit more aggressive with these winds.  The CA WRF has almost 60, but that may be over doing it because there will only be a 6mb gradient between SAN and TPH.  Either way, with 850mb Temps at 20-22 Monday into Tues temperature will be soaring, with the IE getting close to many 100 in many location.  Corona/Norco looks to be above 100 Monday.  RH is going to be single digits of course, so the fire weather will be critical.  Always holding my breath watching these develop from up here in SLC.

Very thick clouds today, but no rain or drizzle until now. Some reverse clearing is trying to get going.

[DareDuck]

Visiting the southland for the weekend. Absolutely perfect weather today. Not looking forward to triple digits Monday. I was skiiing in OR last week!

[Guest happ]

NWS_LA is reporting 0.10 for USC today but none of the other NWS stations in LA county/ Ventura county recorded rain; likely a malfunction. There were some rain totals of a few hundreds of an inch in San Diego county and a fair amount of rain in northern Santa Barbara/ San Luis Obispo counties.

Coldest day of the fall so far, but looks like the coolness will not last long.

[Thunder98]

It was cool and windy yesterday. Had some brief drizzly light rain Friday morning,

 

High: 69F

 

Low: 50F

 

Precip: 0.03” (Airport)

A few low clouds still remain this morning as offshore flow is slow to develop. Should be a nice day today.

[Guest happ]

Tied lowest minimum for month: 58°. San Diego recorded 59F on 10/10; that is lowest for USC also. Wonder when both USC/ Lindbergh Field will record minimums below 50?

[Anti Marine Layer]

Still rather mild today as the heat wave does not begin until tomorrow. Tomorrow will be the last day of the year that the sun reaches more than 45 degrees above the horizon at its highest point of the day.

The day may get hot, but it is off to a rather chilly start.

[Guest happ]

Light steady ENE wind overnight. A check of usual santa ana wind prone stations [Fontana/ Corona/ Santa Ana canyon] show low velocities so far. The worst fire danger conditions were in NorCal earlier this month but now SoCal is facing severe risk this week.

The high today was 91F!

[Dylan]

We hit 91 here today with a morning low of 48.

[Anti Marine Layer]

Today's temperatures will be similar to those of June 20, 2016 west of the mountains. That day was the longest day of the year. Today the sun will not even reach an elevation of 45 degrees above the horizon for L.A. and Orange County.

 

If we were in standard time, sunset tonight would be 5:07 PM, just 21 minutes later than on the Winter Solstice. The Equation of Time is the reason for such early sunsets just one month into the fall. Today is the first of 21 days in a row that solar noon is either 12:34 PM or 11:34 AM.

[Guest happ]

No reports of significant fires despite wind; hope it stays that way.

 

Sunday: 94/ 64

Ouch! It was 108F on 6/20/16 here. I don't think it will get that hot but this is the 9AM data close by.

Already up to 106 F in Fullerton. It will not make it to 122 F in Palm Springs, however.

Incredible for this time of year. Too bad there isn't an official station with long term records in Fullerton.  

 

The closest is Anaheim, which only goes back to 1989. They've never been above 102 this late in the fall (11/3/2010). 

 

The closest long term station (Yorba Linda, back to 1912) has also never been above 102 this late, although they did reach 105 on 10/19/1940. 

[wx_statman]

107 at Fullerton and 104 at Ontario Int'l today. Neither place has long-term records but I imagine these are the highest readings so late in the fall for these locations.

 

At least 104 in Long Beach and 102 in downtown LA, which are both late-season records. 

[Guest happ]

Some minimums in the 70's and 80's include: [max in parenthesis]

 

Yorba Linda: 79 [105]

Lake Forest: 76 [105]

Fallbrook: 74 [102]

Getty Center: 83 [102]

UCLA: 75 [100]

Chatsworth: 83 [99]

Van Nuys: 80 [104]

 

Most of these areas are in wind-prone corridors so night temps can stay warm.

Looks like today was the hottest day of the year for Fullerton Airport. It is still very warm outside this evening.
