The GFS being the GFS as usual. Once again this will be an exercise in futility wishing for an I-95 snowstorm that isn't happening. +AO, +NAO, no 50/50 low, -PNA, +EPO, +WPO. That does not equal I-95 snowstorm, never has never will. it couldn't possibly get anymore hostile

I don't think anyone said I-95

But there is truth to what you are saying

This fits perfectly with my inland elevated theorie. And when I say inland elevated I mean 84 north and 1,000' or higher

Looks like the pattern improves from 12/27-1/7 with a western Canada ridge and more -EPO. Could give us a couple threats, the first on Tuesday.

Still expecting a warm pattern to return from appx. 1/10-1/20 as the vortex moves back over the EPO/WPO regions. At least we have a window, though.

How much snow does nyc normally see before xmas, anyway?

Seal a deal or two during that 10 day window, and suddenly the season isn't that horrific anymore.

Not sure elevation will be too much help in this situation. Warm air will be flooding in aloft. But yeah, areas north of I-84 in the Hudson Valley could see quite a bit of ice.

Also, I'm a bit wary of long term forecasts. It's fun to speculate but sometimes they aren't helpful at all. This December was unusual in that all mets were unanimous in forecasting above average temps well in advance. And even then, no one predicted that it be would this warm. Same with last February. No one really foresaw the kind of cold we had last year until it was upon us. If you recall, many people (on here and elsewhere) were starting to throw in the towel for that winter until the Euro picked up on that monster blizzard in late January.

FWIW, ENSO filtered JAN MJO phase 7.  It's low correaltion since there are so few examples, and the blocking portion of this is likely overdone (i.e., there's very little probability of this pattern this year being nearly as blocked up).  New Years timeframe does look like it will introduce a brief period of variability to the pattern however.

Edit:  Here's what DEC looks like fwiw as well.

Elevation always helps. Except when you're really looking for CAD.

Goes to show how this El Niño is not fitting the other super analogs. Normally you would see allot of marginal airmass storms where elevation is your only hope

A single poster here said look at the HV which looked reasonable off that 1 op run , I would like to be N of the pike for this one if you ask me but how that got extrapolated into an I95 fight I must have missed that.

I'm thinking a 2-4" front ender here at best, and a good cne/nne jit.

I'm about 15 mi n of the pike.

You well never, ever see anyone predict 3SD anomalies, whether they be positive or negative departures.

Ever, and with good reason.

" Here is a map suggesting we may eventually see some blocking this season, but it doesn't fit my agenda, so ignore that part" :lol:

 

I have no agenda other than to get the forecast right.  Also, the timing for this would be 7 days away...

 

I've seen a lot of this on the twitter sphere recently...people thinking that anyone who puts an ENSO filter on the MJO composites has an agenda.  That's not remotely the case.  What I'm pointing out is that ENSO filtered MJO analogs right now would argue a lot more blocking than is realistically possible right now because of a strong stratospheric PV among other things.

Oh, you meant currently.

I apologize for the joke......I misinterpreted.

My bad.

I would dismiss this normally except there's a very strong high pressing south. It reminds of 2007 where it was in the 70s one day and sleeting two days later.

You also see this a lot over in Texas/OKC and the other plain states, which normally leads to significant icing events.

Good analogy.
