snow_wizard Posted December 29, 2015 Report Share Posted December 29, 2015 Definitely looks like an impressive poor mans cold spell coming up. Even the first precip being shown after the long inversion is going to be close to snow. 1000 - 850 thicknesses just barely above 1290 at day 9. It appears Mother Nature may be set to pull every trick out of the bag to keep the chill going for a long time. As I have said before...anything beats ugly dying warm fronts which is typical Nino fare after December. It will be interesting to see if that weird ULL a bit down the road will give the cold snap a bit of extra oomph. The WRF says it will, but then again I think it's too warm the couple of days before that feature moves overhead. Quote Death To Warm Anomalies!

snow_wizard Posted December 29, 2015 Report Share Posted December 29, 2015 I just want to comment on ECMWF weeklies again. I looked at them today and it shows the NW with below normal 850mb temps for the entire 18 to 32 day period. Not really Ninoish. It does have a distinct minus AO look to it which is not always a bad thing for us. 3 Quote Death To Warm Anomalies!

Didn't exactly pan out that way.The weeklies have honestly been somewhat mediocre this winter. That week-4 depiction looks way off to me, though I don't expect the modeling to grasp the ramifications of the strat/tropical forcing conundrum this far out.

Bryant Posted December 29, 2015 Report Share Posted December 29, 2015 I think it's pretty noteworthy a colder than normal January may be in the cards with this strong of a Nino. With the MJO slated to be favorable for us again by mid January we may even get another stab at something meaningful.As Phil has been saying, there's quite a battle shaping up. The wave bombardment on the PV has began cooling the equatorial upper troposphere/lower stratosphere which helps to create instability, allowing the convective nature of the MJO to ignite. If the PV continues to cool the equatorial region and the MJO gains amplitude, then yes, we have a chance at retrogression and arctic air down the road. I'd say it would be closer to the end of the month rather than middle, but it's a ways out either way. Phil mentioned to me that an MJO wave which has a high amplitude over the Pacific is much more likely to make a full cycle or 2, so root for a strong MJO as it propagates eastward. If ENSO wins out in this battle, our winter is pretty much done most likely. Mean forcing would be over WPac/CPac with little hope of MJO activity outside of Nino regions. 2 Quote Link to comment Share on other sites More sharing options...

It will be interesting to see what happens. One thing for sure is the ECMWF has been much better at forecasting the MJO than the GFS this season. The ECMWF indicates it will be done with the unfavorable regions for us in about two weeks. Could take a week beyond that to get into region 2. During this current cycle 2 - 5 really tanked the PNA. Now with the AO about to crash a big minus PNA could really pay off. In the meantime we stay cold. We could pull off a super Nino miracle! 1 Quote Death To Warm Anomalies!

Front Ranger Posted December 29, 2015 Report Share Posted December 29, 2015 The western third of the U.S. is averaging about +2.5F (including all of the PNW), while 92.9% of the U.S. is running warmer than average. One of the warmest Decembers on record, as of now. That's a nationwide torch, for all intents and purposes. No need to split hairs. Not splitting hairs to point out that map will look easily cooler for the West by month's end. Quote A forum for the end of the world. Link to comment Share on other sites More sharing options...
TT-SEA Posted December 29, 2015 Report Share Posted December 29, 2015 ECMWF sure is boring. Inversion cold notwithstanding... there is not much to track or follow now. I will have some crusty snow on the ground which is better than nothing... and the mountains are buried and skiing will be great so its not like the inversions of the last couple years. But I have been intently tracking all of the snow chances for the last couple weeks and now I am sitting here looking at the models with no interest at all. Pretty sure we come out of this period with another long warm, rainy period. Yes... there might be a little snow at the transition but that is so hollow compared to going into cold with snow.

TT-SEA Posted December 29, 2015 Report Share Posted December 29, 2015 It would actually be snow this time. For the record... this statement is wrong and another example of very wishful thinking. If Seattle did get into the precip today it still would not be snow. It would be drizzle with dewpoints in the mid 30s. The set up on Sunday was much better with a dry air mass in place before the front.
