Phil Posted December 16, 2014 Report Share Posted December 16, 2014 I know what your winter outlook said. But you've definitely made comments in the past week indicating you were leaning away from the New Year and closer to mid January for the Western blast. No worries, you gave yourself originally a wide enough window of late Dec to mid Jan, and yes, your comments have always fit somewhere in that window.You can interpret my posts however you'd like, but if I felt I needed to change something, I'd highlight the fact that I'm doing so. I provide these "windows" to allow myself some wiggle room, as I'm never going to be able to nail the timing these progressions 100%.

snow_wizard Posted December 16, 2014 Report Share Posted December 16, 2014 The ECMWF and GFS are very far apart right now, but the ECMWF has consistency and strong support from its ensemble going for it. This new ECMWF is solidly cold. Very nice. A white Christmas isn't out of the question with that solution. 2 Quote Death To Warm Anomalies!

I provide these "windows" to allow myself some wiggle room, as I'm never going to be able to nail the timing these progressions 100%. Absolutely. I'm just going off of what you seemed to be saying (repeatedly): the PV gets destroyed around New Years or shortly thereafter, and then the East gets hit first with Arctic air, and then likely the West by mid January, probably including the PNW in a coast to coast ice box. If you got all of that exactly correct, that would be amazing. So kudos ahead of time if that happens. It just didn't sound to me like you were thinking the West would get hit as soon as around New Years before, although you did think the Arctic train could begin rumbling south into the U.S. by then.

bainbridgekid Posted December 16, 2014 Report Share Posted December 16, 2014 I feel like the North interior is due for a winter blast. There is definitely some bias at play here... but the continuous cold and dry events become very repetitive without some snow along with it. Unfortunately, the North interior scoring usually comes at a cost of anyone south of Seattle receiving rain.We'll always have February 23rd, 2014. 1 Quote Everett Snowfall (510 feet elevation) Snow since February 2019: 91" 2023-24: 6" 2022-23: 17.5" 2021-22: 17.75" 2020-21: 14.5” 2019-20: 10.5" 2018-19: 24.75" Link to comment Share on other sites More sharing options...
wx_statman Posted December 16, 2014 Report Share Posted December 16, 2014 Understood. As I mentioned before, I look at these things from a macroscale standpoint..you generally almost always see these airmasses max out and slide SE along/east of the mountains as angular momentum is conserved. The mesoscale stuff is mostly out of my league. There is no arguing that. I wasn't out to prove anything btw. I just wanted to highlight an event that challenged the normal progression of things (December 1968), even though technically it didn't defy physics.

Gradient Keeper Posted December 16, 2014 Report Share Posted December 16, 2014 Tonight’s ECMWF run was excellent and almost bitterly cold for us. Pattern change begins in just 7-8 days upstream/offshore. This is in the believable range with the ECMWF. GFS, GEM? Not usually. Also, with the Kona low northwest of Hawaii at 160 W and what looks like a building southeastern US ridge, this could be quite special. I would still like to see the Alaskan block slightly further west, a bit stronger, and more amplified, but I’m not complaining. Very important to note as well that this matches up almost exactly with the New Euro Weeklies, so perhaps we’re going to see support building for this and eventually the disagreeing GFS/GEM hop on board. If we see runs the next 3-4 days reveal a sharper southeastern ridge, rising heights over Great Lakes area, and 500mb over southern Alaska at 564dam, look out! 1 Quote Link to comment Share on other sites More sharing options...
VancouverIslandSouth Posted December 16, 2014 Report Share Posted December 16, 2014 Still looking good for some wintery weather toward the end of December, it's nice to see the models have been backing away from amplifying ridging over the PNW. Instead we have a low amplitude ridge developing slightly offshore with plenty of energy riding over it. This feature develops 120-150 hours out so we're not talking long range lala land anymore. If that thing can get an opening in the Bering Strait this place will be buzzing around Christmas:http://i131.photobucket.com/albums/p286/jemeric/gfs_namer_153_500_vort_ht_zpsfed64d18.gif Quote Link to comment Share on other sites More sharing options...
snow_wizard Posted December 16, 2014 Report Share Posted December 16, 2014 It would get windy if it got really cold. It doesn't always work out that way here.

One problem I might have is the timing of the PV-bifurcation..it will depend on how long it can maintain a barotropic structure..once it goes baroclinic, it's toast..but that might take until the 2nd week of January, unfortunately..a tad later than the 2012-13 breakdown..

Gradient Keeper Posted December 16, 2014 Report Share Posted December 16, 2014 White Christmas?6z GFS is looking good and definitely a step in the right direction trending towards the ECMWF. Pattern change begins after day 7 and 500mb is favorable with a Rex Block that evolves into an Omega Block. It is close to being a major arctic blast. Things turn very chilly Christmas eve/Christmas Day as 850s fall to -4 to -5c with POSSIBLY some snow around PDX metro. Yep. Seriously. White Christmas looks likely Gorge east and above 500-1000'. Arctic blast arrives just after Christmas from Bellingham and throughout the Columbia Basin. Eventually westerlies undercut the block for increased precip chances(Snow/ZR) after day 10. This could be a very snowy pattern. It's encouraging, but yes, it's only one run. Let's see how the Ensembles shake out and 12z runs later this morning. Just for fun at face value December 28th - December 30th would feature an incredible Winter Storm/Snow Storm for the Willamette Valley/PDX metro, then turning into a very severe Ice Storm possibly. This is still 7-8 days out until we see a major pattern change begin, so we can only speculate at this time, but it sure is fun isn't it!12z GFS in 3 hours 32 minutes12z GEM in 4 hours hours12z ECMWF in 6 hours 11 minutes 1 Quote Link to comment Share on other sites More sharing options...
