MJO812 Posted November 26, 2020 Share Posted November 26, 2020 Eps has a negative NAO and a positive PNA. It has been years we have seen this combo. Link to comment Share on other sites More sharing options...

I believe December, 1988 (also a strong La Niña) had a +PNA run from 12/1 - 12/15 before it flipped. The late November strengthening period for this Niña has begun in earnest, the easterlies are really ripping right now and are projected to continue to do so well into December. Regions 3.4 and 4 are about to see another big SST drop from the upwelling. This is going to really limit how far MJO waves can propagate before they get sheared apart by the very strong easterlies and run into the colder waters....which is why MJO phases 3-6 are favored this winter it also sounds a lot like 2005-06 Link to comment Share on other sites More sharing options...

wdrag Posted November 26, 2020 Share Posted November 26, 2020 2 minutes ago, bluewave said: We had 5 years since 2000 produce a 4”+ snow in NYC during the first 2 weeks of December. The first important feature was enough east based -NAO blocking from Greenland to Iceland. A 50/50 low was important for locking in cold air and high pressure across the region. Finally, a far enough west +PNA block was needed over Western Canada. The current ensemble forecasts are not quite there yet. They are lacking the strong east based -NAO blocking in the Atlantic. Not much hint of a persistent 50/50 vortex and high pressure over the Northeast showing up yet. The +PNA block is still a little to far to the east across Canada. 5 storm composite EPS day 10 forecast agreed on all .. at least the southern stream is cold and active. No one in the media talking about a high impact event in OHIO-MI early next week. Sort of surprised... maybe I'm reading this wrong? 1 Link to comment Share on other sites More sharing options...

However, interesting that the GFS and CMC continue on it...CMC GGEM in fact sooooo far west, keeping us warm again. Interesting times with transitioning teleconnections. See blue wave below.

KEITH L.I Posted November 26, 2020 Share Posted November 26, 2020 13 hours ago, bluewave said: Yeah, the rapid warming of the Indio-Pacific warm pool favors a slower and more amplified MJO passage through 5-7. We have seen this quite frequently during recent winters. Even during stronger La Ninas, we can get a January MJO 8 sandwiched between the warmer 4-7 phases in both December and February. So it will be interesting to see how the MJO progresses this winter. Question about MJO.I know some of us on the board claim it's the determining factor in determining weather in the east.Then why was it in phase8,9 and 1 in November and we got record breaking heat?Also some of our biggest snowstorms here have been unfavorable phases.Is just one factor or just part of the equation?

This month the very strong IO MJO combined with a near record polar vortex for November record warmth. So it really enhanced the upper ridge over the area. The closest MJO composite match for November was a phase 3. You can see the dominant VP anomalies focused near that part of the IO. 1 Link to comment Share on other sites More sharing options...

Allsnow Posted November 26, 2020 Share Posted November 26, 2020 I think our best shot of snow will be as the pna ridge starts to retrograde west into Ak. This will allow colder air to enter the eastern US. With a active southern jet and colder air in Canada we will have our chances. I welcome this pattern change as it’s diff then anything we have seen in the last two years. 3 1 Link to comment Share on other sites More sharing options...

JustinRP37 Posted November 26, 2020 Share Posted November 26, 2020 I do wish I had half the optimism for this winter, snow wise, as the majority of the people posting in this thread. I just don't see anything to give me hope of a white Christmas, let alone an average to above average snow year. We will see, but it would be nice to have a good ski season for a change.

All the ensembles don’t roll the ridge over which would pump the southeast ridge. 1 Link to comment Share on other sites More sharing options...

First week of December temperatures averaging slightly above normal in the Northeast. Second week closer to normal. As others have mentioned, maybe we can put some snow points on the board during the second week. This is followed by our annual warm up approaching the solstice and through the holiday period. Yep. Niña look comes back week 4. Week 3 looks great with pna and -nao. 1 Link to comment Share on other sites More sharing options...
