August was all about fog


Here's a satellite image of how it rolls in overnight, fills the bay, gets over some of the hills.












Below: Taken at Marin Headlands, looking SW.
The fog can't quite get over the 1000 ft. hills, but it can sneak in at sea level,
the Golden Gate is to the left.



A few days it backed off, we got some nice relief.
It almost looked like it might rain... but no such luck.





Weather out west is largely tied to elevation, and it's effect
on whatever is coming in off the ocean.
Hills and mountains squeeze the air mass.







It snows at higher elevation, it rains lower down.
The peaks of mountains surrounding Death Valley are always snow covered.
At the bottom of the valley, it can be hotter than hell. Literally.

Shot from Dante's view, looking NW at sunrise.

But not always - there' been a very persistent hi pressure system
in the four corners area, when it expands westward, 
the natural air conditioning of fog stops working. Like now:


What will fall bring us? Ocean currents creating fog start to shift, fog backs off, September
and October can be the hottest months here at the coast.
I'll be sittin' here in front of my Mac, in boxer shorts, 
Canon Powershot at the ready.


Who knows what tomorrow may bring?!

Summer Fog! ..and one stunning sunset...


6/21 - There was one stunning sunset in SF:



..... not so stunning just a few miles north, where i am.
I am looking for something truly different, like this:



Here's one excellent link:

Here's some nice cirrus, 6/16:






(A little something to break up the monotony of totally blue skies.)

Sat. 7/9 - By 1PM,  low clouds/fog starts advancing inland - a cool breeze blows in my window.
Love that natural air conditioning! This continues thru the month, it is a bit of a mild rollercoaster - the 7 day forecast looks like this:



Sunday 7/24

Wasn't expecting any good fog, just wanted to cool off a bit from San Rafael's 85ยบ afternoons.
Satellite image showed some fog, but offshore, not thru the Gate, or on onto the land. The Nat'l weather service text display product said the marine layer was shallow, about 1000 ft., which is ideal for photos at MH.
The NWS was right, the sat. image was wrong! - by the time i got there (an hour later, fog doesn't usually move that fast), it was doing my favorite thing, pouring thru the gate but burning off by alcatraz & struggling to get over the coastal hills (only 1000 ft high), burning off in marvelous mystical wispy strands.

The bus schedules had changed recently, but i was in luck, got one to the GGB as soon as i arrived at the transit center, and the one back to MH as soon as i got to the GGB.

Fog seems to have this pattern about it here - it burns off/backs off for a while in the AM, then early PM sometime it starts moving back in, and can overwhelm the headlands w/ pea soup, very cold. That's what it did today, with a vengeance. I waited for the bus at the last stop east before going over the bridge, and it was all i could do to stand up it was so windy. And the wait for the bus back to Marin county was loooong, traffic across the bridge was moving at a snail's pace. 
But the pix were worth it.
















'Ah'll be back' as the terminator said most famously.

What did the rest of May and June bring? Mostly boredom!


Absolutely nothing noteworthy. Nada, Zilch. The next few months? Perhaps maybe some fog, off the ocean.
Fog is our (=those who live close to the Ca coast) natural air conditioner, it sweeps in overnite, the morning is overcast, it burns off to the ocean by midday. The daily weather report becomes a mantra = 'low clouds and fog extending inland overnite, receding to the coast by midday, temps? 60 at the coast, 70-80 around the bay, 90's inland'.
I'd like to be well paid for being so repetitive!
By mid-afternoon, it can surge in again from the coast. 
On Sun, May 29, i went to Marin headlands, and that was exactly what happened, it surged in again at mid-afternoon.


Sooooo.... let's think 'coastal fog' whaddaya say?


Whoaa!!Not so fast..........!!
Recent days, June 12 or so, have brought some interesting things to the Bay area - two systems ( a low and i high) have rubbed up against each other, and made 'looking up' a lot more interesting :-)

441 PM PDT WED JUN 15 2016

"DISCUSSION...as of 1:55 PM PDT Wednesday...Under partly cloudy
skies, area temperatures are running cooler than yesterday at this
time at most locations with most readings in the 60s. Moderate to
strong west winds are also occurring with many airports reporting
gusts from 25 to 35 mph. The gusty west winds will diminish late
tonight. Meanwhile, clouds are increasing from the north as a
frontal system approaches northern california.

The upper level low will drop southward just off of the Pacific
Northwest Coast tonight. As this occurs, a frontal boundary will
move through much of Northern California bringing shower chances
to at least the northern half of the district late tonight and
Thursday. Rain is forecast to begin in the far North Bay after
midnight and spread south into the San Francisco area by late
morning/early afternoon.

---------------------

Rain? In June??
This I've gotta see to believe!

At Wed. 7:30PM? Barely a cloud in the sky. Thursday brought lots of nice skies though.












There was a nice sunrise in there. It was cinematic - changed constantly, minute by minute.
Here's about 1 hrs. worth out my north facing windows:









Who knows what tomorrow will bring?! - I'll be back!

This El Nino was a bust!


Winter went out with a whimper, no bangs to be had here.


3/14 - 19 - like summer without the fog.
Sunday 3/20 things begin to change.......
It looks like it's all heading north of me, just brushing Nor. Cal. a wee bit.
By 11AM a few drops, enough to make the street wet.
3PM - light showers, very bright skies, not much of a cloud layer, not much of a 'storm'.
3/22
My open window is whistling at me - i used to live in an apt on the 4th floor of a marvelous apt. building in SF, 12th Ave, just north of GG Park, never modernized ( thankfully) i could open the kitchen ( west facing window) and the living room window ( east facing ) and almost fly a kite in the apt. It had the original phone, a bread board pull-out, an ironing board, and pull-out seats and kitchen table. Makes big use of small spaces.
This wind is almost as nice. It shakes the small palm plant in my window, i can feel it on my cheeks. I would love to be back in that apt., but SF real estate has gone *whacko* the last 15 years. I'll bet the apt i paid 550$ for is now worth close to 2K$.
March 22 - Conditions were ripe for rainbows:
Rainbows over San Francisco

In the course of doing some rainbow research, i came across this:
Wowee-Zowie!!
April 9-10 Weekend
This might well be winter's last gasp.
Mucho rain, mostly at nite, i wake up at mid night Saturday for a quick trip to the bathroom, and outside my window? Cats, dogs, (and other small mammals) comin' down. The New Yorker magazine sells a nice umbrella, that is cats and dogs :-)

4/21
An interesting day for clouds:
We're 'sposed to get some rain tonite, tommorow, but nothing to get excited about, showers is about it, probably to move south of me by early PM. Thru the night, some nice rain. By 7 AM friday, it looks like it's over, but looks can be deceiving - By 8:30, skies have turned ugly, i get rained on, on the the way to work. But that's it - the skies are filled with huge beautifully puffy cumulus. There are long range forecasts for another round like this one, middle of next week.
4/25 - some serious wind, 'knock me over even though i walk with a cane' wind.
5/5 - In the last 10 days, a few systems have come ashore, but not much rain where i am, close to the coast.
The real action seems to be east of me, as the front passes over the Sierras - read latest entry in http://weatherwest.com.
Here's what the snow pack looks like:
-------------------------------
I wish i had seen more skies like this, this winter:
Guess not. Summer is right around the corner, and that means coastal fog... if el nino doesn't mess with that too.

A few good links worth checking out/bookmarking:
Sierra Nevada Snow Won’t End California’s Thirst
By Henry Fountain - APRIL 11, 2016
And a story of how it came to be:

"Our foundation of Earth knowledge, largely derived from historically observed patterns, has been central to society’s progress......
But as Earth warms, our historical understanding will turn obsolete faster than we can replace it with new knowledge."

A good read, for sure. The New York Times will never let ya down :-)

It just might look like this 'til september:


I'll survive this, no problem ;-)
