A significant cyclogenesis event in the North Pacific will be the primary catalyst of a pattern change over the next few days. Let's take a look at the evolution over the Pacific into western North America. Notice our N Pac storm gets dual jet support and really goes to town over the Aleutians. Wait isn't that where a massive ridge was last week? ... or for that matter the last three months. Well that's one thing that changes. The ridging once over the Aleutians and Bering Straight retrogrades west, while the N Pac storm breaks cyclonically northward. It's really a beautiful event. Minor flat ridging over the eastern Pacific gets pumped up into the Gulf of Alaska, with an intensifying polar jet streak pushing north into the Yukon. What happens after that? Fantastic classic anticyclonic wave breaking into British Columbia! The result is a 170kt+ northerly jet diving into the Pacific Northwest. So you know the trough and all that energy bottled up over Alaska and the Gulf? Well a lot of that comes pouring southeast on the wings of this jet into the northern Rockies So that's the atmosphere's plans for Saturday.

Ahhh I want to be back up there! Great pics man!

Aurora forecast for this weekend! Too bad we're counting on darkness and clear skies ... both of which may be difficult to come by http://www.gi.alaska.edu/AuroraForecast/Alaska/2012/07/14

11th anniversary of my favorite snowstorm

Good stuff Ryan. Mind blowing. Absolutely incredible

I read a little of it in a coffee shop in Keene. The author went to Keene High School and wrote for the Sentinel (the local paper)

Probably about half of the snow on the ground in Plymouth is from the pre-Thanksgiving storm

Absolutely amazing!! That band is incredible. I can't believe I wasn't home in Keene for it.

12" in Keene, which was a little "disappointing", but significant nonetheless And the model watching was the most excitement I've ever had with a storm I have to say. 20-30" in eastern NY, western MA, and S VT where a few days earlier partly cloudy skies were a justifiable forecast. Absolutely incredible.

I hope it comes in January. I want to look out the window at night and see what looks like a thick fog from blinding heavy snow

Living vicariously through a case study of the Dec 2002 storm right now

Nino and +QBO ... Definitely a crappy winter next year.

Also just for fun, here's a total snowfall forecast from the NAM for the 2008 ice storm, in NAM fantasy range...

Here's a snapshot. Will probably has a couple gigs of ice storm 2008 porn saved

If you love it, do it. Pretty darn simple I love meteorology

I'm surprised the JMA hasn't completely removed humans from the field.

Thank you very much! This thread has changed my life. I'm going to switch my major to art
