NYC/Tri-State Area: Stumbling into January Disco

It got killed in the Dec 27 storm. It tried to track the thing over Cape Cod even just 3 days out and it ended up over upstate NY west of SLK like the Euro had it. Complete failure. I would never trust the GFS over the Euro unless there was a very good reason to like the Euro being against its own ensembles or something.

GFS only managed to beat it in the 12/23 system...otherwise its getting thoroughly beaten as usual.

make sure you tell Tip too

Meanwhile it's in the low to mid 20s area wide. Are we supposed to have late highs or something? It's now cloudy so I don't see temps rising much at all anymore.

As far as I understand it, temps should slowly go up as the night goes on w/ WAA.. This is what will give us the slight chance (more of a chance Central NJ) of some snow this evening.. (very light, if anything at all)

Tomorrow should be noticeably warmer as will the next few days..

...And then we have these. Analog skewed, weenied out, and sure to get metfan foaming at the mouth. I present to you, the GEFS super ensemble height anomalies at 500mb with a Aleutian block extending all the way to the Davis Straight and Greenland.

The lower atmosphere is super dry, seeing flurries would be impressive given the amount of dry air and little QPF.

Yeah, I agree. However, because I am bored and feel like being a weenie today (lol), FWIW, the HRRR does seem to have a good handle on the dry air at the surface.

Also, my dewpoint has been slowly rising:

The HRRR shows dewpoints rising in the teens by this evening, and this:

So yes, it will still probably be tough to get anything other than stray flurries - but who wouldn't take those? :lol:

If the GEFS super ensembles are even close to being right, old man winter will back with a vengeance. There is overwhelming support for a pattern change, and we all know that. It starts with the pacific and eventually ends up in the atlantic. Second half of Jan thru Feb may put on quite a show...

Question to those more experienced with stratospheric warming: from what I assume, it takes time for the warming to have a more significant impact on the overall pattern, but at the rate that it's going now, about how much time would it take for the pattern to react and become colder and snowier than it is now? Also, does the current stratospheric warming signal what type of pattern we might change to, such as an interior, gradient or a coastal pattern, or will that become more evident later on?

*** ALERT *** 12z GFS and EURO both agree on MAJOR PATTERN CHANGE coming for Mid January . Both Models shows large scale cold air / possibly arctic air mass outbreaks by Day 9-10 over entire eastern half of the CONUS.. not 2 or 3 day shots but some serious WHAMMO!!!

A map of beauty there -AO and building -NAO scream cold and stormy potential taken verbatim

That ridging near Greenland actually stays there for over 24 hours this run without quickly moving away... Looking back through December and most of November, I can't find any other example of a Greenland set up like the one on the ECM.

If one were to extrapolate the Euro after day ten, I would bet the heights over Greenland would continue to build westward since the PV in that vicinity has been destroyed. Look at that pacific! The -EPO builds and delivers an arctic attack over the eastern us...we knew it was coming..just a matter of when...

I'm still not really convinced plus latest gfs long range has a lot of resistance to the cold air mass that tries to slide south. The fact that it shows such a massive cold air supply on our side of the globe is a positive sign, the decline of the AO is a huge sign, but any changes still seem so far away.

Prospects are increasing for a major east coast inland rainstorm for next week that seems like a precursor to a potential pattern change.

I'm still going with this being similar to what occurred in 1997, 1999, and 2000, the January switchover followed by a mild February. I just do not see there being enough of a change in the high latitudes to cause this whole shift to last for the rest of the winter.
