Chewbacca Defense Posted December 15, 2016 Report Share Posted December 15, 2016 How does the set up look for Whatcom County this weekend? I have relatives coming in tomorrow and flying back out on Sunday. They will have kittens if they are not able to fly out on Sunday.... Anyway, I was trying to figure out if this is a scenario like last weekend where the cold air got scoured out everywhere except Whatcom and points north....

BLI snowman Posted December 15, 2016 Report Share Posted December 15, 2016 Going to end up as their most impressive cold stretch since Dec 2008. And 2008 was their most impressive cold stretch in a long time, as far as duration goes. Definitely feels reminiscent of 1992-93 so far. 1 Quote Link to comment Share on other sites More sharing options...

TT-SEA Posted December 15, 2016 Report Share Posted December 15, 2016 12Z ECMWF shows some lowland snow on Christmas morning as a system is moving in... hard to tell if it would transition quickly since day 10 runs out through 4 a.m. on Christmas. The control run of the ECMWF ensemble is wonderful for Christmas weekend with a storm digging into CA and cold air across the PNW. Not sure about any precip on that run. The ensemble mean basically agrees with the operational run at day 10.

Knowing that area, if they moved it from the south end of the airport to the northwest end it would make a difference. Another thing about SLE. Records go back to 1892, obviously there was no airport then. No one has ever been able to tell me where the observations were taken in Salem before the actual airport opened...Was it in that exact location? I find that unlikely as back then that would have been outside of town.

Definitely. Euro ensembles are on board for Christmas weekend possibilities as well. I know there are still quite a few people on here wishing they'd had more snow to this point, and that's understandable. But the reality is we're looking at a rather cold first half of December that brought multiple rounds of cold and lowland snow, with more cold and probably some lowland snow within 72 hours, and beyond that looks promising as well. Could be a lot worse. 1 Quote A forum for the end of the world. Link to comment Share on other sites More sharing options...

I would say it feels at least as much like 1984-85, 1970-71, or 1961-62.I've been experimenting with dozens of analog compilations over the autumn, and thus far, this one has verified the strongest in terms of the 500mb departure over the NHEM. The NPAC is by far the best match on this compilation, though still imperfect. Here's what these -ENSO analogs predicted for O/N/D.

Kayla Posted December 15, 2016 Report Share Posted December 15, 2016 12z EPS mean is showing 31/17 day at PDX on Saturday. Pretty impressive. It usually does pretty well with temps so Saturday could be PDX's coldest low since 2013 I believe. 1 Quote Cold Season 2023/24: Total snowfall: 26" Highest daily snowfall: 5" Deepest snow depth: 12" Coldest daily high: -20ºF Coldest daily low: -42ºF Number of subzero days: 5 Personal Weather Station on Wunderground: https://www.wunderground.com/personal-weather-station/dashboard?ID=KMTBOZEM152#history Link to comment Share on other sites More sharing options...
