Near identical cloud free morning though stratus can be seen here and there on satellite especially Orange county.

Socked in with this terrible marine layer today.

[Anti Marine Layer]

Low was 70 this morning even with the low clouds and apparent coastal eddy.

[Thunder98]

The sky has cleared up now.

"By Monday, July 23rd, a 598dm high pressure center sits over the
high desert area of southeast California. There are good
indications that this giant high will not move much at all
through the end of July! By Monday our 950mb temperatures will be
close to 35 degrees C for inland valleys and 40 C in the desert.
Although this doesn`t appear to be a repeat of the early July
heat wave when some temperatures reached 117 degrees in the San
Fernando Valley, it definitely looks like a very long duration
event that builds and compounds heat impacts over time." 

[Anti Marine Layer]

Not sure if the sky is filled with thin cirrus clouds or high smoke. There is no smoky smell, but the sunlight seems to have a slight orange color.

[Guest happ]

I noticed the same cirrus shield moving northward. 

 

92.3°

Normally this is as warm as it gets and perfect for ocean swimming in SoCal:

 

S. MONICA BASIN:  73
S PEDRO CHANNEL: 73
CAMP PENDLETON: 76 
OCEANSIDE OFFSHR: 76 
SAN DIEGO BAY: 76 

POINT LOMA SOUTH: 71

Staying seasonably hot

[Anti Marine Layer]

Cooler day today, but still pretty hot.

[Guest happ]

I was convinced that the marine layer reached my location but nothing at sunrise or after. Looks like it was quite close by per satellite. There was a pleasant coolness early this morning.

At least it is windy in Hawaii
 

[Guest happ]

Wonder how long the elevated SST will last?  In 2015 ocean temps stayed quite warm well into October/ responsible for very warm nights

Coolest day since July 4th

Early marine layer arrival tonight.

The marine layer came into Orange last night for the first time since before the 4th of July. It likely wasn't very thick, but at least it was overcast last night.

[Guest happ]

12 maximums of 90+ so far this month; not even close to records. Last July had 17 days but this summer appears to have the potential for nasty hot. 24 days of 90's [including 2 days 100+] in July 2006.

 

Average July max/ min: 87.9/ 65.3. Lower elevation [below 1000'], unobstructed transport of coastal air/ SW wind off Long Beach/ Orange county restrains heat a bit here compared to Pasadena/ higher foothills.

 

It is cool tonight; already down to 70°

[Guest happ]

I checked my records, and it looks like I also had 24 days of 90+ in July 2006, with 20 consecutive (92/70 overall).

 

August 2012 averaged even hotter overall (94/70), but had just 20 days of 90+ (offset by 8 consecutive days of 100+, a record I hope never to challenge).

 

Seems likely I'll break the 20 consecutive 90+ streak this July, unless I don't manage to crack 90 tomorrow.

 

Today Pasadena was 92°but forecast to be only 89° tomorrow and Burbank 91° per MOS

Coming all the way from Texas

"An easterly wave over eastern Arizona this evening will move
beneath the ridge into Southern California on Tuesday, followed by
another wave on Wednesday, currently sitting near the Big Bend of
Texas. An increase of monsoonal moisture will occur on Tuesday and
into Wednesday. Less marine layer stratus coverage should be
expected as the moisture will play tricks on the marine layer
inversion. "

[Anti Marine Layer]

Looking very June like this morning.

[Guest happ]

Marine layer definitely covers the San Gabriel valley/ foothills this morning though it appears the San Fernando valley stayed clear.

Easterly wave has migrated into Mexico. Whoops! Or maybe it was deported by Trump.

[Guest happ]

Dew points are on the rise again making for uncomfortable outdoor conditions. Building cumulus to the east.

The streak lives!  Eked out a 90º at 3:47 p.m.

 

13 and counting...

Not here but it became so humid today that it felt much warmer than it was.

 

88/ 68

[Anti Marine Layer]

Low clouds came in early tonight and the satellite loop looked more like June today, but with the warm sea surface temperatures, the marine layer did not have its usual strong cooling effect.

[Guest happ]

Mesoscale convection [MCS] is mentioned in the summary today but thick high clouds may suppress rain.

[Guest happ]

There's some encouraging reports of rainfall this morning in lower Coachella valley [indio Hills: 0.31]

Interesting forecast for Santa Maria!

 

[Guest happ]

Infrared shows activity in Central California and building thunderstorms in western Arizona. Hopefully the monsoon flow into SoCal will continue into the evening.

Locally. This evening's clouds

 

[Anti Marine Layer]

No thunderstorms here. Just another humid day, but not extremely hot.

[Anti Marine Layer]

Low clouds made another early intrusion last night and then got pushed back out in middle of the night.

[Guest happ]

Excessive heat watch in effect for early next week per NWS_SD.
