January Medium/Long Range: A snowy January ahead?

That period 21-24 is honking imo across guidance and has been for a couple of days. Alas, things can pop in the short range with these patterns so we wait patiently and continue to monitor.
 

Yea there’s ways to win and fail, we don’t want the eventual trough to come East as one event. The runs that give us snow seem to hold back energy while allowing the cold front to clear first.

This fits the trailing wave idea.

That’s a nice look.  I’m just so pleased to see the ensembles keeping it cold basically through the end of January.  It looks like our “big warmup” next weekend maybe be a few days in the 40s.  When is the last time we’ve made it through January without a big thaw and at least a few days in the 50s?

Any signs of blocking returning? I’m big-game hunting and this first round was a swing and a miss from the big-game standpoint. Weird how we couldn’t seem to ever get a high pressure to the north as noted by the poster above me.

It will have to reshuffle if a big -ao/-nao is coming back. Mod/strong EPO ridges generally feature a neutral or + ao/nao because it's awful hard to fill the entire arctic circle with high pressure. 

Blocking slows things down and spreads out shortwaves which is good when they have their eyes on you but terrible when your on the outside looking in. I'd prefer blocking but there are advantages to progressive epos when it comes to precip events. They are spaced tighter and more frequent. Pick your poison because it NEVER comes easy here lol

The reason we couldn't is partly because of the massive vortex- our would be 50-50 low that was displaced SW of that position. The other part was the flow between the ridge out west and the TPV contributing to a lot of NS shortwaves feeding into the vortex. Even though it's weak, in a Nina the Polar jet tends to be busier and the STJ less prominent, so that's another contributing factor.

As for blocking going forward, the ens runs were depicting a Scandi ridge retrograding into the NAO space, but have backed off on recent cycles. There are still hints, so we shall see on that possibility.

If you look at the blocking regimes and observe the NAO there is significant potential for a classic Mid Atlantic SECS event, during the favored window of Jan 18 th to Jan 25 th .  

Current forecast do not show any deep dives in the AO or NAO indices.  NAO getting ready to reverse near Jan . 20 th

The driver is the EPO.  

As Tomer states the increased risks of SECS can extend days past the end time of the Greenland High regime.

I'm keeping it simple going forward. Epo patterns are frustrating to figure out beyond 5 days and even then.... I'm not getting married to anything until it's inside of that range. Think of an epo driven pattern as one dude holding an open firehouse. Yea, you can kinda aim it where you want but it sprays all over anyway. That spray with flow is make or break. Expect nothing to lock in and hold mid range and beyond. It's a game of windows and not events.
