2017 California/Southwest Weather Thread

[Guest happ]

Doubt that there is a chance to avoid 100+ degrees today but it will be only the second triple-digit day this year.

The fog is now trying to clear up

[Thunder98]

If this verifies and if no marine layer inversion happens. It will be hot and very warm overnight lows.

 

[Guest happ]

More thunderstorms scattered about in some mountain/ desert areas. Monsoon looks to remain active into next week.

It is muggy again, even though temperatures have stayed below 100 within 10 miles of the coast.

[Guest happ]

Ouch! This is the current 8AM temp in the higher foothills north of my location. It is only 79° here [Lo: 78]

Looks like today could even be hotter than it was yesterday. Dewpoints are also staying high, making it humid.

[Thunder98]

Cumulus humilis or Alto-Cumulus castellanus? Very cool cloud patterns.

 

 

 

[Guest happ]

Some good vertical development again over San Gabriel/ San Bernardino mountains but rain reports are modest [under 0.10]. Dew points are fairly high but not nearly as muggy as it was earlier in August.

Something to keep an eye on; some models [Canadian] suggest this moisture reaching California next week.

Hot and humid now, but in a few weeks we could get our first Santa Ana Winds, which would make it hot and dry. Would be nice to see some monsoon activity west of the mountains.

[Guest happ]

Lightning is observed but the cell must be fairly far off since I haven't heard thunder yet. Hopeful that rainfall will spill into the LA valleys/ basin tonight. Very warm evening.

12Z GFS brings Linda all the way into Southern California by Sunday...

 

[Bonk]

Toasty...

 

 

[Anti Marine Layer]

Dark clouds to the east, but they will likely not affect the coast. August starts and ends hot and muggy.

[Thunder98]

Amazing Cumulonimbus build up this after noon and even a very rare overshooting top.

I would like to see some tropical storm remnants bring some activity to Socal, like Dolores did back in July 2015. Hopefully it verifies!

[Anti Marine Layer]

It feels like Miami out there. There are storms all around us, but no rain here.

[Anti Marine Layer]

Dewpoint in Fullerton is higher than in Houston, which has literally become a swampland.

[Guest happ]

Just miserable heat today/ tonight [still in the 90's at 9pm] but great cloud formations and thunderstorms scattered about [wish it would rain here].

Photo captures conditions across SoCal today; mainly brief showers.

[Thunder98]

Very hot and humid weather this weekend and even a chance of thunderstorms on Monday due to monsoonal moisture and remnants of TS Lidia stream the moisture into California!

 

 

 

[Guest happ]

August was close to monthly averages. Two weeks of cooler than average maximums help offset the heat early in the month and extreme temperatures late in August. Warm sea surface temps contributed to higher than average minimums.

You live in a unique coastal climate of cool summers/ mild winters

[Anti Marine Layer]

Not quite as humid today, but temperatures are hotter.

[Thunder98]

95F now, 5 degrees hotter than forecasted.

[Thunder98]

It's a very hot and humid 106F in SLO! A very muggy dew point of 65F!

 

[Thunder98]

It's now 97F! 7 degrees hotter than forecasted. The low temp this morning was 56F. There was a brief seabreeze this morning right around Sunrise.

[Thunder98]

Pop up thunderstorm in the mountains.

Visible satellite shows smoke from southwest Oregon drifting well out into the Pacific and TS Lidia hitting Baja California

103F tomorrow!!!?

 

[Black Hole]

Chino airport was 115F today, that is really cooking even for the inland valleys. 

[Thunder98]

The High today was 100F! Today is the 1st time it went above 90F and 100F. Big diurnal range as well. The low was a very nice 55F.

 

 

[Anti Marine Layer]

Not too often that we have offshore flow and 70 F dewpoints on the same day. Dewpoints have dropped since this morning into the low 60s, and offshore winds look to continue as moisture from Lidia moved in.

[Kayla]

106º in downtown San Francisco today?!? Shattered their all-time record high by 3 degrees. That's incredible!

[Guest happ]

Afternoon clouds may have kept maximum below yesterday's reading. Wind is light and mostly offshore so smoke from fire in Tujunga/ Sunland is staying away tonight.
