January Medium/Long Range: A snowy January ahead?

This colder/active stretch looks much more like a nino than nina in the northern hemisphere. I talked about this in the fall. I never thought this winter would behave like a typical nina. Nino hangover no doubt has its hand in the cookie jar. One of the reasons I was a little bullish early on. I had some good guesses this fall so far but they were just experienced based intuition guesses. I get that stuff wrong plenty but my confidence was high this year for reasons I can't really explain even to myself lol

Does it continue? Idk. Guy says nino hangover look will break down and not come back. We're getting pretty far into winter now. If things stay colder/active they, I don't think it will look the same. Prob getting ahead of myself but intuition is telling me that a more zonal/boundary type regime will be the next money maker if there is one. Less amplified pna and hints of a SE ridge. Blocking can flatten the ridge and create zonal flow with cold fighting warm. If that happens the gulf will be involved by default. Just throwing ideas around. I cannot predict the long range future any better than mets, models,and longtimers here. Much uncertainty lies ahead 

Mjo has become stronger and is progged to stay in Phase 1 longer. Odd for a Niña and much more common in a Niño.

You may not have seen my other post to Bob that I  do believe, after any "thaw", a return of winter end of February in early March. Could be wrong, but who cares. And modeling may change, since my thoughts are based on current modeling.  But our best pattern should be this month into early February, so that's the real reason for my hope to score soon and often now, redundantly speaking notwithstanding! Lol 

Oh I definitely agree, but up here I will say often we pull off a win in an "ok" pattern more so than the lowlands in this sub, that's where we can get a win.  There are plenty of examples where my snowiest week of the winter came during a blah pattern up here after disappointing results from a much better one.

I wouldn't mind a 5-6 week stretch like what happened in 14 or kinda what happened in 15. Hitting with those borderline events which our areas maximize potential on.

The 500mb troff collapses, so the precip does too.

A subtle but seemingly critical difference between the Euro and GFS has to do with timing/degree of interaction with NS shortwave energy(of course) digging southward that's associated with the vorticity lobe south of Hudson. GFS phases some of that energy sooner and acts to pick up the southern low, placing it closer to the coast. Euro is lesser/later with the interaction, so that energy acts so suppress/kick the low offshore.

It’s really wild to think about how well forecasted 1993 was ahead of time. 

Triple phase storms show up at long leads because (usually) there is a phase no matter what. Big dogs have special ingredients. They aren't subtle. 93 tripled and became a record breaking beast but a large strong storm was already a near guaranty well in advance. Its been a long time since the last triple....maybe we're due... heh

I totally agree! It is just funny that we trumpet our ability to create technology (especially AI) but are unable to get a better handling on weather in the short / medium ranges. If that went away, what would us as weather hobbyists do with our time?

Look at actual verification scores, we have improved significantly.  Day 5 scores are similar to day 3 from 20 years ago!  Peoples expectations just continue to increase faster than science in this area.  But it wasn't all that long ago that forecasts only went to day 5 (remember TWC 5 day business planner) and day 5 was unicorn fantasy land.  Now we look out to day 10 in the same way but expect better results.

Precip actually angled a hair better vs 6z, but still don't expect any significant changes wrt out amounts

SS getting held back/left behind a bit makes it hard to gain much neutral tilt to get that orientation to climb the way we want it. Maybe it'll pull it off anyway.

Fair point!

You’re still going to hit hard limits with chaos theory
