Hazy view of mountains with some snow on top, not much lower down. A city skyline is visible between the mountains and a canopy of trees and low buildings.

From yesterday: the first significant snow in the mountains above Los Angeles this winter, courtesy of last week’s storm.

Unfortunately, it’s almost spring. The weather has already warmed up again. Last week I was wearing sweaters and a medium jacket. Today I’m back to short sleeves, and I had to put the jacket away on my lunchtime walk.

And there’s not much of that snow left today.

KQED has some great photos of snow in the Sierra Nevadas after the same storm. That’s more important, as California depends more on the Sierra snowpack for water during the summer.

They’re expecting another storm to come through next weekend. I guess we’ll see how much snow we get. And how long it sticks around.

Smoke rises from Mt. Wilson above Los Angeles on Tuesday around noon. The wildfire has threatened the observatory and critical communications towers. Today it’s too hazy to see anything but the barest suggestion of the downtown skyline, much less the mountains behind it. Not that it looked quite this clear even on Tuesday – I ran the photo through auto white balance to make everything easier to see.

I’m reminded of the last time the mountaintop complex was threatened by fire, during the 2009 Station Fire… and the photos I scanned from a 1992 tour of the observatory, wondering if that had been my only chance to see it.

We went out to a hill to view last night’s Independence Day fireworks after an afternoon at a family barbecue. Some years we go down to the beach for a closer view. This year the process of getting there, finding a parking space (usually very far away), walking all the way down (and all the way back up) with a small child, finding a viewing spot, and afterward spending over an hour to get out through clogged streets just wasn’t appealing.

So we went to a hill a mile or so away, joining a standing throng of people waiting for the local show to start. To the east and southeast we could see distant fireworks lighting up the horizon from San Pedro to Norwalk. Around the corner we could see a similar view of fireworks to the northeast, including Los Angeles proper.

It’s one thing to see one fireworks show at a time. It’s another to look out and see them all along the horizon. It’s unifying, appropriately enough.

We’d only been there a few minutes when the seaside display started. The next ridge of hills blocked the lower fireworks, but we could see most of them above the hill — without the deafening booms and smoke. The wind was blowing inland off the ocean, a smoke plume trailing sideways. As the finale hit, someone nearby set off their own unsanctioned display, to considerable applause.

After it was all over, we stayed for a few minutes, looking out at the more distant displays still going, then walked down the hill to the car and drove home.

The faint boom-boom-boom continued for hours, punctuated every 15-20 minutes by some closer pop! or shriek as someone set something off nearby. Sometime around midnight, it finally tapered off enough that I drifted off to sleep.

Giant LAX free-standing letters, with snowflake decals added to them.

Even in sunny Los Angeles, snowflakes symbolize Christmas and winter. It snows here, what, once every 100 years? (And we’re likely to wait even longer in the future.)

Update: The day before I posted this, KCET ran an article (with a photo gallery) on the history of snow in Los Angeles. It turns out it used to snow roughly once a decade…until 1962. It hasn’t snowed on the plain since. It snows in the higher mountains just about every year, and the San Fernando Valley (higher than the coastal plain) got a snowstorm in 1989. But the LA basin? Nothing in the last 54 years. Los Angeles is about 5°F warmer than it was a century ago. Half of that can be accounted for by the urban heat island effect. The rest is atmospheric warming.

Check out the KCET article – they’ve got some amazing pictures from LA snowfalls, mostly in the 1930s and 1940s.
