2017 California/Southwest Weather Thread

[Guest happ]

2nd day in row per CPC that heat will end next week

 

[Anti Marine Layer]

Dewpoints have fallen in the desert, but it's probably too late to allow 120 F.

[Guest happ]

There is the possibility of upper level moisture circling the ridge into SoCal this weekend; that would certainly be considered monsoon-like and keep high dew points.

 

92/ 69

[Anti Marine Layer]

Avalon Airport, which is on top of Catalina Island, is currently above the marine layer. They topped out at 92 F. Avalon Harbor was only 64 F.

[Anti Marine Layer]

Thicker marine layer this morning. Beaches are once again likely not to see much sun.

[Anti Marine Layer]

There is actually a little bit of drizzle this morning. Also the marine layer depth reached Avalon Airport. Could be much cooler than the forecast today.

[Anti Marine Layer]

Dewpoints are up in the desert again this morning. The Catalina Eddy also seems to have returned, for a much deeper marine layer.

[Guest happ]

It was overcast earlier this morning for the first time in quite a while. Today should be cooler than 90F here but intense heat continues further inland w/ unrelenting misery in the Central Valley. Even Sacramento recorded dewpoints in the 70's last night. Swamp coolers don't do well in that kind of humidity. I hope convection increases in the Sierra but fire danger remains high.

[Guest happ]

Here's one of the reasons the Central Valley is experiencing dewpoints more commonly found in Louisiana than California. Daniel Swain also attributes the "dry" AR flow from 12 days ago for leaving moist air under the ridge.  The state has allowed deep irrigation for agriculture to alleviate water volume in the reservoirs.

A few beaches in San Diego County cleared better today, despite the deeper marine layer, but for Irvine it was a typical June Gloom morning, not clearing until about 12:30.

 

Quite a change from yesterday. All areas cooler than expected today.

[Guest happ]

Back to more typical temps for a change; didn't need AC today

 

84/ 62

[Anti Marine Layer]

San Diego only got down to 66 F overnight, but they may not make it to 70 F for the high.

[Anti Marine Layer]

They messed up the forecast again today. Much faster burn off than yesterday morning and there was no drizzle.

[Anti Marine Layer]

Clouds burned off early and then returned to the beaches and a few miles inland this morning, then stayed there pretty much all day. Catalina Island helped to clear northern Orange County beaches. Despite being cloudy almost all day, Lindbergh Field reached 74. Marine layer has been quite unpredictable lately. Probably another few weeks yet before the beaches have consistently sunny afternoons.

 

Now some mid and high clouds are moving in. Nice change from clear blue sky or gray stratus clouds.

[Guest happ]

High clouds, some lightning reports offshore but no rain in forecast. Yesterday was delightful compared to the past week or so.

 

Friday: 83/ 65

[Anti Marine Layer]

Another strange morning here. At 7 am it was getting bright looking like the sun was about to break through the low clouds. Then it got really gloomy until about 8 am and low clouds cleared about 8:30 am.

Must have been the high clouds passing over that made it dark.

 

Inversion is an incredible 16 degrees Celsius today.

Inversion has well exceeded 20 degrees recently. I am looking forward to subtropical clouds w/ rain [at least in the higher elevations] as the monsoon develops.

 

Thunderstorms in NorCal yesterday

Beautiful clouds this morning and Mammatus clouds.

 

 

 

 

 

 

 

 

[Guest happ]

If models maintain agreement then we will be under the trough of coolness. Manna from heaven esp for Inland areas including deserts].

 

It was 82F an hour ago; fairly strong onshore winds in my walk. Currently: 78.8

[Guest happ]

Clouds overhead

 

[Anti Marine Layer]

It's hot here in Lake Forest. How can Downtown L.A. be 69 after reaching 75 earlier this morning?

 

Even Lindbergh Field is 73.

Clouds and fairly strong wind. Still cloudy/ cool but the cirrostratus is moving north. Stubborn stratus at the coast for the most part.

122 again for Palm Springs. Wow!

 

Gotta be the hottest ever considering the monsoonal moisture around today.

It went from 82 to 72 in one hour and then back up to 82. That is strange.

 

UCI was cool and breezy, but sunny. Marine layer clouds were visible towards the coast.

[Guest happ]

It ended up being quite a nice June day; probably hot tomorrow.

 

84/ 62

[Anti Marine Layer]

So Palm Springs was hotter than forecasted today at 122. Can they repeat that again tomorrow and break their all time record of 123? Just let one of the beaches top out at 64 and we will have a 60 degree coast to cactus temperature gradient.

[Anti Marine Layer]

Less marine layer this morning, but the intense inland heat will likely keep the beaches chilly overcast skies or not. Still hoping to see Palm Springs reach 124 F today or more. They were higher than forecast yesterday and are warmer than yesterday morning at this time.

 

Meanwhile it looks like Arizona has lots of monsoonal moisture.

Morning dew points are in the 50's or lower in Arizona currently but the low 70's in Imperial Valley and generally 60's elsewhere in SoCal. Humidity needs to rise in Arizona/ New Mexico to kick the monsoon into full swing [that won't happen this week]. I can't say I like high dewpoints but can tolerate humidity if it means summer rainfall.

This is a popular fishing area 100 miles south of California.

[Anti Marine Layer]

Palm Springs was one degree lower than yesterday at this time, with dewpoints still pretty high.

 

Hotter here today so far, but nothing too brutal yet as there is a light sea breeze.

 

Avalon Airport is above the marine layer again.

[Anti Marine Layer]

Laughlin was 118 yesterday. I remember being there in weather just about as hot as that, but the Colorado River was probably as cold as the Pacific Ocean, like mid 60s water temperature. So basically you'd go from the fiery furnace to freezing cold, but once you got out of the water, in a few minutes you were dry and hot again. Gotta wonder if the river ever gets a mist or thin fog over it during the night with such a contrast in temperatures, especially in the areas where it is a mile wide. I think the air temperature in the middle of the river could be about 5-10 degrees cooler than the land on some days.

On the other hand Lake Havasu can have water temperatures in the 80s or low 90s. That was a different summer though and I think it was later in the year.

I also remember being in Laughlin at a time when the river was warmer, but probably still mid 70s water temperature. That was also probably later in the summer.

[Anti Marine Layer]

95 F so far for Fullerton Airport. Hottest day yet of this heat wave and first one above 90 F.

[Guest happ]

I am a little puzzled by how hot it was today in areas close by but much cooler here. Burbank is a mere 10 miles west of my location but was 15 degrees hotter @ 111F. Nearby Pasadena hit triple-digits [100°] but normally is several degrees warmer than my station.

 

96/ 66

[Anti Marine Layer]

Seems like there was some offshore flow this morning and then the sea breeze took over. Dewpoints crashed with the temperature spike in Burbank and then shot up again.

[Anti Marine Layer]

Microclimates once again at work for high temperatures today with Del Mar Beach at 64 F, Lindbergh Field at 77 F, John Wayne Airport at 83 F, Fullerton Airport at 96 F, Burbank at 111 F, and Palm Springs at 122 F.

[Guest happ]

NWS_LA explained how they underestimated offshore north wind surfacing in the San Fernando valley yesterday resulting in widespread maximums between 100-111F. I actually thought for a second that the hourly condition reports were incorrect since Burbank can be seen from my home in the foothills and I was observing mid 90's less than 10 miles away. One reason is that the San Gabriel mountains served as an obstacle and the wind was actually blowing from the southwest here w/ dewpoints in low 60's while north wind lowered dewpoints radically and raised the temp in the San Fernando valley. 

 

There was a light north wind last night keeping minimum in the 70's; another hot day but cooling is coming soon.  

 

L: 75 [warmest minimum this year]

[Anti Marine Layer]

Palm Springs slower to cook up the heat than yesterday morning, but dewpoints there have reached a swampy 70 F.

[Thunder98]

No marine layer at all this morning and last night, the low today was 50F.
