Well, it's still coming down here in Riverside, CA. It's been raining all day, and now through the night. I'm fine with it down here in So-Cal, but those poor devils north of here, and even in the San Gabriels, will have more than just comfortable precipitation.

Flood basins near you must be looking crazy, especially as they spend 99.99% of their time bone dry.

For a long time, the "atmospheric rivers" were more commonly known as "the Pineapple Express" because the moisture came from the region around Hawaii. Heavy, warm moisture...that dropped copious amounts of rain.
Weird, I was going to express the same dang thing. Here in the NW, that's all they used to call them until about 5 years ago, then "atmospheric river" became the thing.

Predates the internet. When they finally got together some research, it allowed them to discover many such weather patterns occurring across the globe, a more formal term "Atmospheric River" was coined. To the lay speaking out there, it means "You gonna get slammed".

This winter was highly unusual. Third La Nina in a row, and the lower great lakes region here, literally only two weeks felt like winter. Rest of this winter was either mild or extremely warm. Comparable to 2020, maybe exceeds it. Very different causes between the two years. I hope someday they do the research on it and point out the correlating weather patterns that set this up. Wasn't just La Nina, something else happened along side of it.

The wavelength of the upper level wind patterns is roughly the width of north america, so if you have persistent cool wet weather on the west coast (trough), you'll generally end up with warmer and drier weather roughly around the great lakes (ridge).

I can honestly say that I can't recall a single day that it hasn't rained here in the Bay Area since early December. Maybe there was a day in there and I forgot about it. Today I looked up at a blue sky with practically no clouds, and it was still raining...

They're calling it "atmospheric rivers." Never heard the term til now.


This is easily the most rainfall in 40+ years. There's a reason we are suddenly experiencing such extreme weather. Dry brush igniting in flames over the summer, torrential rains in the winter, one year out of four.

Hoping the lightbulb will finally come on for some people.
Well at least today was absolutely beautiful with clear blue skys and no rain or wind. 61F is a little cold but still took off my shirt swinging a hammer today.

Yeah no rain so far today. It's like a miracle.

No rain tomorrow either. Maybe a little next day, Friday. Saturday maybe hardly a drop. Sunday, Monday, Tuesday, Wednesday, probably some rain. Tuesday especially.

Much more scientific. They want to sound like they know WTF they're talking about.

The NW one is a pot strain.

Get ready for a different kind of high on grass. Soon the pollen count should be amazing.

I dunno if I'd call it bad, but I would go with "forgettable" for sure. But I've felt that way about pretty much all of his movies.

Yea, there's some good parts. I wouldn't add Pineapple express to my movie collection, but I get a good kick out of seeing Lumberg in other movie.

Wouldn't know, I don't toke.
I keep wondering if it's not bad for the brain. If so the damage is done but a coons age ago. That's a raccoon's age ago for the racially suspicious. Old myth was they lived a long time..............

At the beginning of the "rainy season" climatologists predicted a greater than 50% chance that this one would be drier than average, based on ocean temperatures, etc. :rolleyes:

Reservoirs around here were struggling, but are now something like 90% capacity. They still want us to conserve water because the warming trend spells difficulty going forward in supplying water where needed/wanted.

That's an accurate statement of almost all La Nina years.
All that I can remember except this one.

Which makes understanding the driving force behind this particular weather pattern all the more interesting. Only I haven't seen anyone with the data describe the other major driving features.
