Bob Chill Posted December 27, 2018 Share Posted December 27, 2018 4 minutes ago, psuhoffman said: That bothered me some too. But I really suspect it's temporary. You can tell ridging is attempting to develop under the PV and is pressing and over time should dislodge that enough for what we need. That one stick is really all that's between the look we are getting and really good. Additionally I take some comfort that over the years when guidance is insistent in a specific look coming often it will be rushed and we have to wait longer but eventually it usually does materialize. The last couple years when the initial progred flip was a week of two into February that delay was a winter killer. The pattern did eventually get favorable but not until march and too late to save winter. If this pattern gets delayed from early January to late January that's not as problematic to our snow prospects. We should know in 2 weeks. 18z gefs just showed a progression that is basically identical to week 3 on the weeklies. Lol. 1 Link to comment Share on other sites More sharing options...

Beyond that looks fine. I was posting more big picture that if we don't get a stable favorable pattern in place before the end of Jan that it will be tough to have a big year. I think some people forget that “fine” in January isn’t a shutout since we can back into an event when its not a perfectly ideal setup. I know you know this but sometimes a good reminder for others.

PSU, I am curious as to your view of Isotherm's opinion that the atmospheric base state promoted a cold december abset the PV disturbance.

Get the damn AO negative and hold it there for 6 weeks and we'll snow. Also good odds that we'll get one or more big storms. 4 Link to comment Share on other sites More sharing options...

Bob, I know that's your favorite indice, right ? Dive the AO and keep er down and we will be happy here. Maybe we start to see the seeds planted over the next 5 to 10 days re the - AO, and actually see the favored pattern Isotherm is talking about come to fruition. Would be awesome by Jan 10 th we see everything line up so we can feel more secure about the remainder of Jan. Ironic too that the strat caused issues in December with the colder and snowier outcome he predicted. We should have gotten KU ed. 1 Link to comment Share on other sites More sharing options...

Earlier today I think you mentioned that later December warmth was highly common in El Ninos. Isotherm is more the expert. But I do agree the winter was showing it's hand some early and absent the mjo wave and or the ssw we were looking good. But it's more complicated imo. There seems to be some correlation between a ssw and warm periods at the initiation. There is also a correlation with a ssw and warm mjo phases. And there seems to be a correlation between warm mjo phases and late December in a nino. But correlation and causation are two different things. We can observe a relationship but we don't fully understand the causation. So maybe the warm up was inevitable due to some underlying relationship with the nino that is yet not understood. But none of that is important to the point of what will happen going forward as the effects of the warm mjo phases and the initiation of the ssw come off. I agree the effect should be a reversion to a colder more favorable pattern for snow over the mid Atlantic. Link to comment Share on other sites More sharing options...

The progression isn't delayed it's just we're impatient. I remember a couple weeks who we wanted to see the start of the flip towards a good pattern by New Years. We are now. No question the evolution in January is stepping towards better. But I understand being impatient.

I'll only get impatient if we get to Jan 20th or so without a flake and continued hostile pattern on the panels into early Feb. The it becomes a pure race against the clock and that always sucks. I never expected a big winter. I went below climo in the snow contest. One storm can blow my guess out of the water of course but I didn't go in with hopes of wall to wall and massive snow piles. I'm still confident we get some sort of event before mid Jan. Maybe more than one event.... Would be nice to have something to track again. Even a 1-3 that works out would be pretty fun at this point. Having absolutely nothing to track for weeks on end really sucks. All we can do is regurgitate muddy long lead panels and pass time.

frd Posted December 28, 2018 Share Posted December 28, 2018 Interesting thread. I had posted earlier about the GOES and the GFS. Actually I was most surprised to see her last comment that we may indeed get some clarity in a few days about coupling. These differences are almost certainly due to what each forecasts thinks will transpire in the troposphere, since the stratospheric response is fairly similar in each forecast (GEOS actually has a slightly weaker wind reversal). 4:24 PM - 27 Dec 2018 e Replying to @DrAHButler Do you think the models will finally come into agreement on a solution? I do not remember seeing such a wide array of solutions in the medium to long range. I know the stratospheric warming probably has something to do with the model chaos. Curious to hear your thoughts. Amy H Butler @DrAHButler 1h1 hour ago More I'm not sure. But I'd guess the uncertainty is coming more from tropospheric processes than stratospheric at this point. Replying to @DrAHButler In your experience which is more reliable in the coupling? GFS was actually quite poor in the whole SSW event, and usually GEOS does pretty well) Amy H Butler @DrAHButler 59m59 minutes ago I haven't done any analysis to explore which one is actually better at coupling, so I can't say which is more reliable. Thanks for the answer. We should know in the coming days. Link to comment Share on other sites More sharing options...

BTRWx's Thanks Giving Posted December 28, 2018 Share Posted December 28, 2018 I highly recommend following Mike Thomas on Facebook. His posts about patterns and storm development are so informative! What he sees is the fact that models are signaling a huge NAO swing from negative to positive late next week and so far this winter/fall every other transition produced a storm! With the euro weeklies trending towards a colder look, maybe we'll squeeze something out! I'm stealing his graphic. 1 Link to comment Share on other sites More sharing options...

I think the AO is a favorite because both it and the EPO by and large have been one of the major factors in saving winter over the last few years for us. Little to no help from the NAO or SSW Voodoo Dolls (although you all know I am intrigued by the SSW). AO is definitely a way to get it done round here.
