Now & Then: Humungulo Nimbusity

This past week saw a couple awesome days of monsoonal flow-fueled massive thunderheads forming up out over the Valley of the Antelope beyond the Mountains of Saint Gabriel (as illustrated by the following trio of in-transit snaps I took of the magnificence this Thursday):

From the 110 North approaching downtown.
From the 5 North, passing Griffith Park.
From Glenoaks Boulevard in Sun Valley.

It brought to memory a hot late-summer day seven years ago when in order to capture footage of the fluffy stuff’s formations and dissipations, I lugged my laptop and webcam up onto the steeply pitched roof of our humble Silver Lake abode and from it created the following timelapse of all that hot wet and sticky cloud action:

Silver Lake Stormwatch: December 7

rain1207December 7 will live in infamy for obvious historical reasons. The amount of rainfall caught in our backyard precipitometer yesterday will live in insignificance, to the tune of barely more than a third of an inch, or 0.393″ (or 1 centimeter if you’re in a metric frame of mind).

Silver Lake Stormwatch: November 23 & 29

rain1122Yesterday’s something-of-a-surprise storm did more than I’d expected, but first I gotta play catch-up because indeed after last week’s initial weather system brought us almost and inch of rain onto our Silver Lake backyard precipitometer, the day after ended up delivering a little sumpin’ extra that I failed to follow-up with, to the tune of almost quarter inch — 0.22″ to be as exact as I care to be.

rain1129The gray skies of Black Friday were pretty much completely unexpected. Not only were the various weatherfolk reversing course on previous precipitational prognostications, but at the time we turned in near midnight on Thanksgiving, the skies were clear and starry with nary a drop of rain in sight. Needless to say it was a scramble yesterday morning to cover up the already soggy tortoise hutch. Buster was not pleased. Neither was the hammock.

To make matters wetter the Storm That Wasn’t Supposed To Happen hung around until the latter part of the afternoon, ending up adding more than four-fifths of an inch to the seasonal total.

Silver Lake Stormwatch: November 22

rain131122Various meteorological sources were suggesting a 30% chance of additional showers today, but I’m not feeling it so I’ve called a final total of  7/8ths of an inch or 0.88″ to the storm that began dropping rain late November 20 into our backyard precipitomer and concluded with any residual sprinklings yesterday afternoon. Any more wetstuff that might sneak in today or tonight will be factored in tomorrow.

Silver Lake Stormwatch: October 09

rain131009Just in case you think I couldn’t have taken a crappier picture of my backyard precipitometer, you should’ve seen the first one I snapped and was about to use only to finally succumb to disgust and go snap this one, which is only slightly less unreadable. The important takeaways from the results of yesterday’s storm?

1) Don’t rely on my iPhone, and

2) Clean the damn precipitometer.

Technically speaking, this is not the first rain of the season. That one occurred on July 11, and dropped a full 0.02″ (count ’em: 0.01, 0.02!) more than yesterday’s sprinklefest. Looking through the accumulated muck in the bottom of the soon-to-be-swabbed-clean vessel I officially log the total from yesterday’s representative sample of rainfall (that looks like it could be squirrel piss) upon our backyard to be an entirely unimpressive one quarter inch… but hey, every 0.25 counts!

Silver Lake Stormwatch: July 11

rainfall130711Figuring why the heck not, I put out the put-away precipitometer yesterday after hearing that sub-tropified showers and thunderstorms might grace the skies above our Silver Lake backyard.

This morning? I found a skosh more than a quarter-inch had fallen — with perhaps a few more hundredths to come. Granted, not a very auspicious starting amount to the 2013-14 rainfall season (which technically began July 1) — but what is remarkable is that we’re in the middle of summer, and rain during this stretch of the season is a rare thing, indeed.

So, with measurable rain being measurable rain and you gotta start somewhere, this is as good an amount as any.

Silver Lake Stormwatch: May 5-6


My iPhone’s weather app is still trumpeting the possibility of a scattered shower or two throughout the day and even into the night, but it seems a remote possibility, any amount of which might be added to our backyard precipitometer would at best be negligible.

So as things stand this morning, the total from what’s been dubbed the “Miracle May” storm (and the first measurable rainfall around these here parts since March 8) that helped firefighters contain the regional conflagrations that were in various stages of control, stands at 1.625 inches. That surprising amount pushed that which hath fully fallen on our Silver Lake backyard this entire rainy season well up past the 20-inch mark — a far cry more than what’s fallen on the city’s official rain catchers.

And not a moment to soon, since that season ends at the end of June, and until yesterday Los Angeles was officially on track to record its fourth driest season since records started being kept back in 1877. Now it’s the sixth most-parched with an official total of 5.84.”
