2017 California/Southwest Weather Thread

[Anti Marine Layer]

Weather could not get any more boring. Maybe a very small chance for some isolated mountain thunderstorms tomorrow, but I would not count on it. Marine layer clouds have not reached Riverside and San Bernardino since the beginning of July. It might deepen enough this weekend with the Pacific NW trough to do so.

Interesting stretch of hot summers from 1959-61. Came during the longest period of neutral ENSO conditions in modern records (1959-63), and without a coherent PDO signal from late 1958 to mid-1961. In other words, arguably the two biggest coupled ocean-atmospheric circulation drivers of climate variability along the West coast were dormant during that stretch. It's interesting to me that the result ended up being two scorching hot summers in 1960 and 1961. There were all-time record highs set along the West coast in 5 of the 6 boreal summer months during that two year stretch - July & August 1960, and June-July-August 1961.

Appreciate your informative contributions [i.e. Koppen/ Trewartha climate classification].

Beautiful except for the threat of sharks.

Looks like mostly dry thunderstorms in California desert areas but lots of rainfall around Las Vegas this late afternoon.

It was nice to see some distant thunderclouds today. Otherwise not much change in the weather pattern.

[Anti Marine Layer]

Marine layer is a little bit thicker this morning. Yesterday by this time the clouds were already breaking up.

Fogust this morning is slow to burn off.

Just like last year

I'm looking forward to a deepening trough/ stratus. This summer has been characterized by weak/ moderate ridging/ elevated heights. But only one triple-digit day. Last summer had six 100+ days at this date. No significant fires in SoCal could be a result of high dew points/ some good storms further inland [Palm Springs: 0.71 just this month].

Distant thunderclouds were spectacular again yesterday. Looks like monsoon could be done for this summer, starting today. Marine layer has reached Riverside this morning for the first time since early July, and will probably reach the coastal slopes by Tuesday morning.

[Anti Marine Layer]

Low clouds already starting to burn off here, which is faster than yesterday despite the deeper marine layer. There have been mornings with the marine layer pushing further into San Diego County than today, but not reaching Riverside.

[Guest happ]

It will be nice to have below average maximums for a change; something that hasn't happened all that much this summer.

Still can't shake 90° but tomorrow is looking promising for cooler maximums.

[Anti Marine Layer]

June Gloom or Fogust pattern is coming, but it's still a pretty warm marine layer with Fullerton at 70 F this morning.

[Guest happ]

I wonder if we'll really get maximums in the 70's? NWS_LA forecast for tomorrow: LA: 76/ Burbank: 76. Record lowest max: LA: 70 [1976] / Burbank: 74 [1990]  

[Thunder98]

It briefly drizzled this morning.

[Thunder98]

It is very clear outside today with no haze at all. It feels like the very 1st taste of autumn. The Sun Angle is noticeably lower as well now.

Also see some cirrus clouds way out there.

Looking at my station data, 2010 was last cool August [mean: 75.0] but that was a cool summer unlike this year.  August 2004 was coolest I have recorded [74.6] w/ a warmer July & Sept.

It is quite breezy this afternoon.

[Anti Marine Layer]

Marine layer clouds have some holes in them tonight, but they will probably fill in by morning. Fullerton had a high of 80 today.

[Anti Marine Layer]

Very deep marine layer for mid August. SSTs have cooled recently with the persistent troughing. Record low maximum temperatures are definitely a possibility today.

[Guest happ]

Some inland areas may be 20 degrees below average for mid August today.

Very deep marine layer today and the dew points are lower as well.

Clouds are starting to break up a bit here. Still relatively warm ocean waters for a true June Gloom pattern in August.

Seems like the SST Anomalies have cooled off in Central California area.
