72 F on top of the tramway, 112 F in Palm Springs. Quite a difference. Same kind of difference from the coast to the desert, but the drier air in the mountains always feels warmer than marine layer at the same temperature despite the claim that humidity is supposed to make it feel hotter.

[Anti Marine Layer]

Slight chance of showers and thunderstorms is gone for tomorrow for the mountains and deserts. Just partly cloudy now before some record low maximum temperatures possible this weekend.

[Guest happ]

Lightning strikes have been occurring off the coast near San Diego this morning but no rainfall reported.

Some monsoonlike clouds today, but it's not the typical southeast monsoonal flow.

[Anti Marine Layer]

Looks like hottest day so far west of the mountains and today is my last full day in the desert. HUGE two day temperature drop everywhere coming up, which means roller coaster season has not ended yet.

[Guest happ]

A bit toasty but not the hottest day of the year so far [96F on April 9th].

 

94/ 61

[Anti Marine Layer]

Just as hot in the desert as yesterday today and hotter than yesterday towards the coast. However, the onshore push has begun as winds have kicked up in the desert.

 

Very similar pattern to the May 11 low ahead.

[Anti Marine Layer]

Cloudy even in the desert this morning. Very cool weekend ahead, but maybe not as cool as it could be due to above average sea surface temperatures in the bight. It will be quite a change returning to the June Gloom after 2 days of 112 F.

[Thunder98]

Nasty June Gloom today

Dewpoints breaking 70F in low desert; lots of altocumulus clouds preventing stratus formation and suppressing temps.

Just 12 hours ago, the dew points in Imperial AP was 34F! Wild swings

Yeah, it is more like southern Texas than California

IMPERIAL AP CLOUDY 93 70 46 SE15 29.70R HX 99 

[Anti Marine Layer]

Record low highs more likely next 2 days as the exceptionally cool and cloudy June 2003 has one of its few non gloomy days on the 16th and 17th. Still pretty warm today back in Lake Forest.

Rain everywhere but California

Not the rainy season.

[Guest happ]

Not the rainy season.

 

Of-course but with Pacific tropical activity so close by it is frustrating. California stands out as the least rain-friendly atmosphere in the U.S.  especially grievous when ocean temps are warmer than Virginia. 

[Anti Marine Layer]

Temperatures are a little warmer than forecast again today and the forecast highs seem to be a little cooler than I would expect the next 2 days given the warm waters in the bight. Many of the May Gray days last month also had higher temperatures than what is forecast for Sunday.

[Anti Marine Layer]

Desert is more cloudy than the coast right now, but still hotter than the coast.

[Thunder98]

Looks like Summer is arriving just on schedule. Potential Solstice Heatwave next week?

 

[Guest happ]

Much cooler air advection moving southward. Tomorrow/ Sunday maximums could be close to 20 degrees cooler.

[Anti Marine Layer]

Palm Springs had a high of 99 F today.

[Anti Marine Layer]

The cloud bottoms are at 2700 ft this morning, at least for Fullerton Airport.

[Anti Marine Layer]

Inversion already seems to be weakening this morning with some breaks in the clouds.

[Anti Marine Layer]

Wind is blowing strongly from the south while low clouds are letting some sun through at times.

[Guest happ]

Satellite image shows some erosion from high clouds circulating westward out of Imperial valley.  First day DP's are below 60° on coast side of mountains but currently 70° mugginess in Yuma. Temp has only risen 1° from morning minimum.

Only 70 F in Tuscon right now with remnants of Bud directly over them.

[Guest happ]

Up in the clouds. And the coolest region in metro area. Eujunga is missing out

Even with the overcast, it's still quite bright outside with the very high sun angle.

[Anti Marine Layer]

Rather random and strange clearing pattern so far.

[Anti Marine Layer]

On these June days that feel like March, you forget you can get sunburned quite easily, especially with the longest day of the year next Thursday.

[Anti Marine Layer]

Phoenix only 81 F this afternoon, for a completely different reason than the trough causing the deep marine layer here.

[Anti Marine Layer]

Mt Wilson Observatory is already starting to get fogged in.

[Guest happ]

Surface gradient must be very strong.  Strong south wind even here w/ gusts over 25mph and much higher in Palmdale. Mostly cloudy and quite cool this early evening.

 

73/ 63

[Anti Marine Layer]

Deep marine layer now having a cooling effect even in the desert where Rancho Mirage near the 10 freeway is down to 71 F. Last year on June 11, the Palm Springs high was 87 F. In June 2003, they had a high of 85 F as late as June 22.

 

Phoenix was only 82 F for the high, far away from any marine layer influence. The cool temperatures there were due to the remnants of Bud.

[Anti Marine Layer]

Marine layer has made it all the way into Bakersfield this morning.

[Guest happ]

Marine layer has made it all the way into Bakersfield this morning.

 

Stratus enveloped the entire San Joaquin valley this morning; how often does that happen anytime of the year [excluding tule fog?]

 

Some broken clouds here; current temp is 65.9°. Minimum managed to reach 59° even under low overcast.

[Anti Marine Layer]

Clouds never fully cleared out today, but did thin out enough to let some warmth through.
