Snow will come to California’s Sierra Nevada a bit earlier than usual.
Ryan Maue adds: “as this storm pulls eastward, it will “bomb” out or explosively deepen over the Great Plains and move into the upper-Midwest. The barometric pressure will fall to 962 mb 955 mb according to the most recent GFS forecast, making it one of the deepest northern United States continental extratropical cyclones since 1979 for the 30-day period between October 15 and November 14. This will clearly be a historical storm and an extreme event: evidence of global warming La Nina.”

The stuff that’s been coming down here in Eugene, OR, for the last three hours is what we call “rotten snow,” which falls out of the sky instead of real snow in these moderate climes (54ºF).
Wunderground tells me we’ve already got 0.36″ of the stuff.
I’ve been wondering when La Niña was gonna get herself all cranked up! The past couple of weeks have been pretty dry.
Thanks for the addition Ryan. The zonal moisture flow on this system is one of the strongest I’ve seen in October. It will be the perfect angle of attack for enhanced orographic lifting in the Sierra.
The central pressure is already down to 969 mb
Loveland Ski Area opens tomorrow (10/24) and Arapahoe Basin ski area (A-Basin) opens Monday (10/25). It’s snowing and cold in Breckenridge. The big storm hitting Wash. is on its way to Colorado. Looks like a little powder skiing for Loveland and A-Basin next week. A decade ago I recall the news media screeching that “global warming” would destroy the ski industry by now. Another false prophecy of the global warming/climate change/climate disruption alarmists. Snowfall has been above-average for the state of Colorado for the past five winters and is expected to be above average again this season.
Thanks Anthony, just called my son in San Fran and told him to get his snowboard out!
We’re battening down the hatches here in Reno….snow clearly visible from last night on the mountains at elevations that look to be like 6,500ft and higher from where I sit at the eastern edge of the Sierra.
As of Oct 19 we’d had record precip, at 2.2″ for the month-to-date, the highest since 1871. Last record was 2.14″ set in 1945. This is ruining our drought.
Truckee Meadows Water Authority wants to raise rates because we’re low on water. If we get too much water they’ll have to raise rates because there’s …too much water.
Here’s an interesting little piece on the Holocene climate in the Great Basin..

Spector says: at 7:13 pm
blob of cold air will come out over the arc of the Aleutian Islands.
Look for that to get blocked, roar east over Canada, and then dip into the upper mid-west of the USA.
Washington coastal waters now have gale force warnings and the mountains above 4,000 feet (~1,200 m) may be totally white by Monday morning. Studded tires are not allowed until November 1, although the WA Dept. of Transportation often gets on these things rapidly. Makes for a busy time at places that sell and change-out tires.
Time to start up the snowpack machine on the Sierra and the Cascades.
What a beast of a cyclone!
Hey, we tried to tell them to enjoy the Global Warming while it lasted.
Ya never know what you had until it’s gone, though some of us have seen both sides of the coin.
We’ve had a glorious fall in Colorado! We’ve been in that great place between air conditioning and heat for at least 6 weeks. However, for the first time ever, we have a conflict between mowing the lawn and the Halloween decorations.
My flowers are still blooming and my tomatoes are still producing. The grass looks the best it ever has. Bring on more La Nina!
Here’s hoping it continues.

Devil? Al Gore? Why, the man is a saint. Just look how holy he appears:

I think devils hated warm only in Norse mythology, where Hell was a frozen place of eternal ice & snow.
The same will happen in the Alps in Europe the next few days. There was already a significant fall earlier last week with up to 50cm at 2000m/7000ft in the Northern Alps. With further falls and temperatures low, this may be an unusually early start to winter in Europe’s mountains.
Weather being the way it is, of course, the whole lot might melt before next month is out.
Time will tell………..
“The barometric pressure will fall to 962 mb…”
That should be “The atmospheric pressure will fall to 962mb…”. The term barometric pressure makes no sense in this context. Most of us are not concerned about the pressure exerted by a barometer. Try it in Wikipedia and the request is re-directed to atmospheric pressure.
Blowing like stink here in Victoria which is pretty much the eye of this storm. Horizontal rain. But quite warm.
It’s weather but it is wet and blustery.
I blame Bush of course.
And not only in the Sierras:
http://www.meteoexploration.com/snow/snowmapsUS.html
A lot of snow in the European Alps, too.
At least AWG must be good for the skiing industry.
Winter approaching?
Snow on the ground?
Time to repost this National Ice Center IMS Products link.

You should read your own references before making claims.
I thought the “pineapple express” term referred to the typically warm flow of moisture from the Hawaiian islands area towards the West coast. This storm is moving directly Eastward from Japan to the West Coast following the jet. Pineapples generally bring very wet and heavy snow depths to the Sierra. Perhaps this is more of a pineapple modiki ?
I think I am right in saying that the Sierra Nevada range has the worlds greatest snows. One storm dropped 67ft of snow. Perhaps more this year.
A cooling planet is showing what may be in store if we keep up all this AGW rubbish.
Early snowfalls, or snow in places which do not usually experience snow is significant since it has an effect on the albedo. If there is a trend over several years, the change in albedo will begin to reduce the warming. It may also be a sign of changing weather patterns which may also have some significant long term effect.
Hence stories about snowfall are a little more relevant than stories of about very warm weather.
Of course, for most people, we are more interested in the weather than in the climate since it is the weather not the climate that impacts on our day to day lifes. Most of us are more concerned about it being too cold rather than it being too hot.
I recogn that high winter fuel bills beckon.

The heat got fired up today (Saturday). The pumpkins got cut off the vine and everything else gathered up.
It’s pouring with a roar and has been at it all night long. Nice decible level.
I watched as the local meteorologist lowered the weeks temps and snow levels between the 6pm forecast and the 11pm forecast.
The CCR song “Who’ll stop the rain” comes to mind.
This must be the Global Climate Disruption they warned us about!!!
Global warming is coming earlier each year. Soon we will all melt, or freeze, or something.
It’s tough when you predict calamity and the the opposite happens — LOL
Noaa shouts another scary scenario.
.SYNOPSIS…A STRONG STORM WILL CONTINUE TO AFFECT THE AREA TODAY
THROUGH MONDAY. HEAVY RAIN WILL FALL IN THE OLYMPICS…GUSTY WINDS
WILL DEVELOP ACROSS THE AREA…AND GIANT WAVES WILL REACH THE COAST.
TEMPERATURES WILL FALL AND BY TONIGHT SNOW WILL BE FALLING IN THE
CASCADES ABOVE 4000 FEET. DRIER WEATHER IS EXPECTED TUESDAY AND
WEDNESDAY. WET WEATHER COULD RETURN BY THE END OF NEXT WEEK.

Never mind the 4000 foot snowline. We are having periodic flurries here at 575 feet!
