[Thunder98]

Very clear skies in Santa Maria after dealing with overcast skies for all morning and some of the Afternoon today.

Quote from NWS Hanford Forecast Discussion

.DISCUSSION...It`s not often that you can talk about "June Gloom" in the San Joaquin Valley and adjacent foothills, but today started out that way throughout much of this region. As of this writing, clouds are still blanketing the west slopes of the Sierra and the east side of the San Joaquin Valley from Fresno county southward. Otherwise, this afternoon is remarkably cooler than 24 hours ago with temperatures trending ten to as much as 25 degrees lower than yesterday afternoon.

[Guest happ]

15 degrees below monthly average max today

48F with clear skies, not a single cloud in sight.

[Guest happ]

Cloudy here but stratus is breaking up.

Fun fact:

 

Today's maximum here of 61º, set within a few days of the summer solstice, was 20 degrees cooler than the maximum of 81º I recorded on 12-29-17, within a few days of the winter solstice.

 

Eugene yesterday: 

 

MAXIMUM 87 

MINIMUM 49

 

Figured you're in Oregon for summer.  

[Anti Marine Layer]

Yesterday there was little or no haze under the low clouds. Today the haze is back with just a few low clouds left.

 

I've noticed San Francisco does not get haze under the marine layer, but that could have just been the time I was there.

Took some photos in the garden on a cool day in June. This is shell ginger.

Last 3 days were quite cool, but June 2003 had 8 days of highs below 70 F in Fullerton.

[Guest happ]

Cool morning. Under clear skies temp dropped to 57F here but rose several degrees before sunrise when stratus moved overhead.

"Want to find out how much it has warmed in the last 30 years in your area.?"

[Guest happ]

Seth Borenstein's graphic make sense to me since I've been recording daily values here starting in 1995.  I was puzzled for a while that my location was some sort of temperature anomaly compared to historic averages in Pasadena and USC, for example. Urban heat factors in most assuredly even in hillside woodlands.

[Anti Marine Layer]

High temperatures are about average today with the cloud deck over the ocean looking quite thick yet.

 

Low did not cut off over the Great Basin as was forecast last week.

[Anti Marine Layer]

Both the high and low were normal today for KFUL. That does not happen too often.

Basically boring [typical] early summer conditions. It is always a bit painful to watch the Weather Channel [for many reasons but specifically] when so much of the nation, including the PacificNW, is getting in on thunderstorms. Pattern of dry troughs/ relatively weak ridges appears set for now.

Despite the shallower marine layer, this morning has had the gloomiest start of the last 4 days, as the inversion has strengthened.

[Guest happ]

Marine layer was scattered briefly around sunrise but clear up where Eujunga lives, no doubt.

[Guest happ]

Warm day, dew points up a bit.

[Anti Marine Layer]

Marine layer wasted no time blowing in tonight, arriving before sunset.

 

Sunrise was exceptionally gloomy, afternoon was sunny and warm to hot, but by 6 p.m. the cool sea breeze was in full force. By 7 p.m. low clouds already began to arrive

[Anti Marine Layer]

Forecast discussion says marine layer is not as deep as yesterday, but yesterday morning clouds did not reach Riverside.

[Guest happ]

It was an overcast somewhat muggy night.

[Anti Marine Layer]

The coastal eddy is pretty obvious this morning.

 

[Anti Marine Layer]

Julian reached 91 F before 10 AM today. Inversion is super strong with eddy keeping the marine layer deeper than it should be given the high pressure.

It was an overcast somewhat muggy night.

Might be a bit muggy here, but Houston has a dewpoint of 81 F right now.

Much of the East Coast is suffering mightily. I know when DP's hit 70° how everyone here screams "uncle". Nonstop AC is the only solution. Yesterday Pasadena came close to reaching heat indexes but should stay below that threshold today.

I think that barometer reading is a little off for Moreno Valley. It would take a raging Cat 5+ hurricane to produce that type of reading!!

[Anti Marine Layer]

Low clouds are lurking on the horizon poised to make an early comeback again. Summer has officially started. Nice beach weather still a few weeks away.

[Guest happ]

If this is a heat wave than bring on summer!

Clouds were a little slower to come in tonight and the sea breeze was not quite as strong. Looks like the low clouds should keep temperatures rather warm tonight.

[Anti Marine Layer]

For some reason my login is no longer persisted when I check the box to keep me logged in.

[Guest happ]

Usually there is a light breeze especially if stratus is moving onshore like tonight.

[Anti Marine Layer]

Lima, Peru is colder than here this morning, despite the fact that they're in the tropics at 12 S. They have a marine layer just like we do. June to October have very little sunshine there and lots of morning drizzle.

The reading is actually correct it's just not corrected for sea-level (standard) atmospheric pressure.

 

For example my current pressure reading is 24.73" (at 5,350' of elevation) with a standard pressure reading of 29.94". Stations usually automatically correct for the altitude of the reporting site for a standard datum but if it's raw data it might sometimes report as its true pressure.

 

All very important numbers in aviation!

[Guest happ]

The reading is actually correct it's just not corrected for sea-level atmospheric pressure.

 

Same thing this morning:

 

MORENO VALLEY N/A 69 66 88 SW1 28.04S 

[Guest happ]

Temp dropped to 65F around 9pm and stayed there all night under the marine layer. 

[Kayla]

Same thing this morning:

 

MORENO VALLEY N/A 69 66 88 SW1 28.04S 

 

Yeah it's just reporting in raw format but it is reporting accurately.

 

Corrected for that sites elevation (1,631') and converted to standard pressure it would read 29.71"

[Guest happ]

This is interesting

Water continues to be warm in the bight due to the persistent eddy pulling up warmer water from the south. Both Lompoc and Los Angeles started out overcast this morning, but the temperature in Lompoc was 50 F while the temperature in Los Angeles was around 65 F.
