global warming ?????
i don´t think so
> WELL ABOVE NORMAL PRECIPITATION AMOUNTS
What’s normal there for late June? I thought it was zero. Maybe the forecast is for 39100% of average precip for the day.
How will global warming believers damage control this?
isnt it mid summer in the USA? wtf?

Seriously? Because of late season snow? That is weather, not climate.
Wrather, my friends, weather.
Dark clouds rolled on in here about 2 hrs ago (NW Ca.), and have that serious thunderstorm look to them. I may post a pic of the Trinity Alps when it’s over if the snow gets down to 7,000′.
Not unprecedented, but rather rare. Fits the year perfectly.
What do you want to bet this is a pattern we’ll see repeated in July & August?
Reference my comment above: wrather = weather. Typing around a cat. Difficult.
Can you send some of this to Oklahoma?
Rhoda;
Easy and fun solution:
take 1 Tazer … apply as needed.
Ice ages start via a combination of weak summers (e.g. where the melt comes so late there is a high survival factor) and high precip.
In a response to comments about unseasonably high rainfall earlier this year (La Nina years in California are supposed to be drier than average), a post on CA Department of Water Resources daily news summary said that people expect climate, but they get weather. This response cautions us apply reality checks to our observations.
Still, the Sierra snowfall is unusual and should remind us of the unseasonably early snowfall that the Donner Party encountered.
My friends……the paradigm has seamlessly and smoothly shifted to ‘climate change’.
What’s this AGW business you keep bringing up?
Moderate Republican states,
“Seriously? Because of late season snow? That is weather, not climate.
Tornados in the south east of USA in 2011… Global Warming. Above average snow fall in late June in California…weather!
Where am I?

It’s not the weather, it’s the year. A lot of weather rocks have struck long-standing weather windows this year.
Cold weather rocks.
Where’s your popcorn? You’re supposed to be getting into the trend of where this climate thing is going.
Captain Climate to Weather Dive Plane Steering, take her down.
So, you’re saying we shouldn’t let this eat at us? 😉

Rhoda – the only tazer application needed would be to Brian H.
Can hear him now:
Don’t taze me Rho!!!

Here in Fresno we’re likely to get a bit of rain and maybe a T-Storm. That almost never happens this time of year!

This is not a late season storm I predict that it’s an early winter storm for 2011-12. Bye bye, Summer. Hello, Winter.
Here’s hoping it continues across the US and brings some rain and relief. In particular, to the Los Alamos area where there’s a pretty big fire burning. And in Arizona.
And then is followed by several more such storms.
The one really good thing about all this AGW and CAGW hysteria, and especially the money spent to measure the change in climate, is that we will have excellent documentation of the beginning of the next Ice Age. Or, should it prove of shorter duration than an Ice Age, the beginning of the Gore Minimum.
“And the Sun hung like an un-blemished lemon in the sky.” — no sun spots.
Late June in the Northern Sierra is well into the start of the rainless summer. the climate for the area is called Mediterranean. All the precip from late Sept to early June. Art Day, Nevada City H.S., Class of 1950.

Yeah, maybe share it with Arkansas? All the way from the left coast to the right coast would be welcome down south.
Note to all cat lovers=Spoiled cats are worse than spoiled children.
If it’s not weather, you paid too much for your climate model forecast.
La Ninas, unlike lightning, often strike twice, and unlike El Ninos, they do whatever they please.
The climate models are about to get clobbered by a weather semi with no brakes.
Sure glad I’m not in the Climate Model Insurance biz.
