In the mountains 2010/2011 was similar, but from what I've read online it's been 37 years since a similar snowpack was seen. It's on pace to easily be my snowiest winter since moving here.

A look back at history made in Chicago...the year was...1967

Need to worry about the cold first though, just rain without it. The cold itself is hardly a lock too. I'm still skeptical unless the Euro finally jumps on board. Liking the trends though.

Every pattern is different. If you guys are looking for snow up there it is pretty silly to complain about cold coming back into the picture. That is an important ingredient for snow....

00z even further south....

That means they will cost more, though. We pay our workers more. For now at least...

Pretty far out at this point. Plenty can change in 5 days.

I never saw anyone say that she was dying. She had a physical condition, one that made her collapse and cough a ton. That was physically visible and should have been questioned. You, I presume, are liberal, and to say our President has "serious mental" issues/problems is insensitive. Something the snowflakes in their bubbles say they are always not. Can't even admit that what you said was wrong or insensitive. Yikes. Try being affected by family or friends with serious mental issues. It's nothing to joke around about or take lightly

Yep... day 10

Wow. The 12z Canadian is pretty good. Plenty of snow for most. Lots of potential right thru day 10.

12z GFS just buries PDX area once again...

GEM is looking colder this run too.

If we could get a couple weeks like that year for February and then throw in a Blizzard then I would consider this a win for this winter. We would quickly forget how terrible January was.

I was lucky. I actually haven't driven my car since December 5th but I've started it and let it run for a bit a few times. Cleared off 15" last week and it's still running fine. Unfortunately a 3' snow/ice berm is blocking it in so it's still not going anywhere for awhile.

Have you tried shooting some starting fluid into the air filter housing? Sometimes the electronics can get wet if it sits too long also.

Coldest since 1979 is basically a foregone conclusion at this point.

Good to see that at least through the end of the run, the 00z NAM agrees with the latest GFS as far as the progression of the cold air. http://www.tropicaltidbits.com/analysis/models/namconus/2017012700/namconus_T850_nwus_53.png http://www.tropicaltidbits.com/analysis/models/gfs/2017012700/gfs_T850_nwus_15.png

Ugh. At least we'll always have 2006-12.

All models are converging on a solution that indicates there will be at least some weather.

It took a lot of time to dig up data (two of my biggest hobbies are mountain and weather), but I revised and expanded the Fact Sheet Interesting Weather Statistics for US Mountain Summits: http://www.summitpost.org/interesting-weather-statistics-for-us-mountain-summits/171585 Added were a Mt Spokane in eastern Washington; Mount Fanny in the Blue Mountains of Oregon; White Mountain Peak in the White Mountains of California; Mount Baldy in the Wasatch Range in Utah; Blowhard Mountain in southwest Utah, not far from Zion National Park; Berthoud and Fremont passes as well as Mount Evans, all in Colorado; Grandfather Mountain and Mount La Conte in the Southern Appalachians; Haleakala on Maui in Hawaii; and Mount Locke in Texas. Also, since it came up on another thread, I was able to do some digging on the Mount Rainier data. Apparently there have actually been several studies on the summit climate of Mount Rainier, dating back to at least 1960. Some studies used actually data and some interpolations. The latest study just ended in 2016 and the page has a link to it. I hope that you find it interesting.

Yes, I will continue to work on it. A lot of the info is hard to dig up! I would especially want to get more data from the Denali weather station at 19,000 feet.

00z GEM is quicker with the cold as well so far compared with the 12z GEM.

Dry cold is getting old. Never works in our favor. Just slowly moderates, or Oregon gets hit.

Yeah, it's definitely not backing down. Trending colder and colder with each run, good sign.

Flash freeze!

0z has the cutoff low further offshore at day 5 compared to 12z.

00z GFS compared with 12z from earlier today. http://www.tropicaltidbits.com/analysis/models/gfs/2017012700/gfs_T850_nwus_19.png http://www.tropicaltidbits.com/analysis/models/gfs/2017012612/gfs_T850_nwus_21.png GFS isn't backing down on the cold air coming down. Quicker with it too.

While the 00z GFS runs... The all important 18z NAVGEM is on team Euro. Keeps the cooler air locked up north. http://www.tropicaltidbits.com/analysis/models/navgem/2017012618/navgem_mslp_pcpn_nwus_24.png Each run has been ever so slightly trending south with the low and the colder air FWIW.

The UKMET and ECMWF MJO forecasts are very favorable for a NW cold wave during week two. A pretty good wave moving into the MC.

Certainly some nice model trends today. The 12z and 18z moved quite markedly toward a colder solution for next week and the 12z GEM was fantastic by around day 9. The move toward a colder outcome for early next week was quite pronounced on the 18z ensemble.

Snowstorms are kind of trite. Wait until spring shower and 55 degree rainbow season kicks in. I think you'll see activity pick up.

Do you have a 200 square foot apartment?!

Fantastic write-up, man. Keep it coming if possible.

20 percent import tax to build the wall. Genius idea. Who pays for that? Oh ya thats right american consumers.

Dolt could be looking good soon at this rate.

Certainly nice through hour 120. Definitely colder and further South than the 12z, which itself was much further South and colder than the 6z and Euro.

It already has though with the last couple storms. I went against all odds and predicted they wouldn't cut and that's what happened. My expectation is for this to eject into southern plains and then head E/NE but not a Dakotas special.

You think GW unilaterally embarking on a decade-plus, high collateral damage war effort on bogus information against a foe which posed no specific threat to American soil in America's best interest? Or was a horrible federal response to the biggest natural disaster on American soil in America's best interest?

Agreed - lets see how hard this thing ends up cutting. If the blocking that you've been mentioning doesn't show up, people in the Dakota's will be greeted to another gift yet again.

Been awhile since we have seen a major event in southern BC during the Late January-Mid February period. Maybe this is the year.

Definitely. Looking like it might go Canadian past day 8. Blast potential.

Beautiful sunshine and mid 30s right now in Tulsa. Hitting up the zoo. Can't believe My daughter is 4 already.

12z GFS for the Super Bowl weekend system...

The 12z is looking a lot colder by next Monday and sure enough, following the theme of the winter, the low is coming in much further south.

MI will more than likely see some long fetched lake induced bands coming off the lake, possibly reaching DTW area with this type of set up.

. Very impressive totals. Too bad it couldn't shift 50-100 miles south, otherwise many of you out there would have cashed in.

Taking the cold route for sure.

January 2017 already has more rain than we got from all of October 2015-September 2016 for Fullerton Airport. October 2015-September 2016: 5.26" January 2017: 5.45"
