Front Ranger Posted January 17, 2017 Report Share Posted January 17, 2017 Definitely not me..anyone in particular? Might want to avoid calling people out unless you're confident enough to identify them, as I don't think anyone would have made a down-to-the-week prediction months in advance. I will say, though, that the predictions for the breakdown of the +EPO regime in late January turned out to be correct. That's all I've seen predicted.Lol, I was specifically avoiding calling anyone out. Just remarking on the general, popular idea that has been pushed back. Quote A forum for the end of the world.

wx_statman Posted January 17, 2017 Report Share Posted January 17, 2017 I'm not sure if it has been mentioned, but looking back, 1926-27 appears like the closest analog to this cold season. -negative ENSO following torchy Nino (in 1925-26)-significantly wet October-very warm November-Arctic outbreaks in both December and January Its the closest match I could find, going back to the 1870's. 2 Quote Link to comment Share on other sites More sharing options...

Good information... thanks. We were about done with any meaningful cold and snow at this point in 1927. A fairly decent spring in my area with plenty of dry days. Lots of frosty nights and warmish days in March and April implying clear skies. May was not so great but summer was in full gear by the first week of June which does not always happen here. A decent summer as well.

Front Ranger Posted January 18, 2017 Report Share Posted January 18, 2017 Here was his forecast- Thanks. Probably fair to paste what I had for December as well: DECEMBER - Overall, the analogs (both the broader and more narrow sets) paint a pretty clear picture. There is a strong signal for upper latitude blocking to continue on the Euro-Asian side of the globe in December. Much of Asia should remain colder than normal, and western Europe will likely turn stormy and cooler. There is a weaker signal for west based -NAO in North America, leading to much more seasonable conditions in the lower 48, and a good chance of below normal temps over parts of the country. Interior Alaska should turn colder, as a Bering Sea/Siberian high funnels some of the cold air from Asia into northern North America. At some point I'll have to look at the 500mb anomalies for December and then this month and see how they matched up to my preferred analog composite. I think the general idea of a very blocky winter, with -EPO and suppressed jet mid winter, has played out well to this point. - Interior AK did turn colder (relative anomalies) last month, and a Bering Sea/Siberian high did develop and help funnel some of the cold air that had been predominantly in Asia during the fall into North America in December. The lower 48 ended up much cooler than it had been, with about half the country below normal. - There has not been as much -NAO as the analogs indicated this winter, though we have entered a -NAO regime recently. There was west-based -NAO from late November through mid December, but since then the blocking has been primarily -WPO/-EPO. As a result, Europe has not been all that cold so far. - While the coldest weather has indeed been in the west/central US this month, it has been more north-focused than the analogs indicated. The southern tier is mostly above normal. Too soon to evaluate the month as a whole, though. We'll have to see if -PNA returns for February, and more cold shifts east with increased -NAO.

Jesse Posted January 18, 2017 Report Share Posted January 18, 2017 Looking at model trends today, at least it looks like we don't stay mild and wet very long! Big ridge looks to possibly develop the last week of the month. Still deep enough in the winter that we could score some decent fake cold out of it. Might also put us in a pretty good position for a more classic retrograde later on. 1 Quote Link to comment Share on other sites More sharing options...

Jesse Posted January 18, 2017 Report Share Posted January 18, 2017 For those who are still hoping for some action out of this winter, the fact that we look to go into a pretty blocky pattern again in short order (even though the ridge is over us) as opposed to a raging jet and buckets of mild rain like so often follows our long cold periods, is a great sign. 2 Quote Link to comment Share on other sites More sharing options...

I would accept a transition to a 1992-93 analog moving forward. 1993 was a terrible summer... that would be depressing for many. But very good for those who like 55-degree drizzle most of the summer. Seasonal variety at its worst. 1993 was an outlier due to a delayed response from volcanic activity in 1991. Some will say that had nothing to do with it. I would not expect a repeat of 1993 this summer and not just because of my preference that it be sunny and pleasant during the summer months. That was also an extremely wet and cold summer in the Midwest as you know.
