    The History of this online weather world from Eastern to American has Never been “Only a Pro can start weather threat threads.”   You simply don’t like my ranting or me  B).  

    I said cred, not pro!

    How'd (A)I do?

    1/25–26 Coastal Storm Thread: Deep Cold + Moisture Feed = High-Impact Ceiling (Still Volatile)

    Big picture: We’re heading into a major arctic outbreak with a cold high pressing across the northern tier, while a frontal zone + subtropical moisture plume sets up to our south. Guidance supports a significant winter storm from the southern tier into the Mid-Atlantic, with increasing signals that SNE is now in the envelope. 

    Over the last ~48h, there’s been a notable north shift in many solutions, tied to greater interaction/phasing between southern-stream energy and northern-stream energy over the Plains → deeper trough → stronger downstream ridging → farther north storm track. WPC notes this shift is broadly reflected across deterministic/ensembles/AI guidance, but also warns the unanimity could be partly a mirage due to unresolved shortwave details. 

    SNE baseline expectation (as of 1/21):

    • Snow looks increasingly likely late Sunday into Monday, but exact track/gradient still low confidence. 

    • Ensemble spread still supports anything from “a few” to “10+” depending on where the coastal low tracks relative to the benchmark. 

    • With the arctic air mass in place, SLRs could be higher than climo for much of the region where snow verifies. 

     Things to watch:

    • Track vs benchmark (suppressed / benchmark / inside runner)

    • Degree of phasing (deformation/banding ceiling vs quick hitter)

    • Coastal front placement (I-95 jackpot potential vs sharp cutoff)

    The music will live on forever as it should. The Grateful Dead are one of the greatest American rock bands. Legend. 

    I have a few folders on my hard drives of rare photos, music and memorabilia.  
    I’m 57 and definitely met some cool, connected music folks over the years.
     I saw the Grateful Dead for the first time in 1985 at the Providence Civic Center. Sophomore in high school, my parents drove me and a buddy to the show!  
    That was a quiet drive home. Lol.  

    I know you are a Phish fan.  Maybe I’ll see you sometime at a GTG because I have some great stories of seeing those guys at clubs and hanging out with their posse. 

     

    Very cool you have that stuff. Pretty special, and definitely one of if not the greatest American rock band, ever.

    I'll have to give that show a listen.  I was born that year, and similarly saw Phish for the first time as a Junior in HS, Worcester Centrum 2003.  I am going to be an inconsolable mess for at least a week when one of them passes.  

    I always enjoy hearing stories about the journey going to shows leads one on.  To me, that's such a big part of the whole experience.  That's where a lot of the best memories are, and when some of the deepest friendships I have were formed.  If you were around for the club days, I'm sure you've got some good ones - would love to hear them sometime over a beer.  

    Cheers!

    Love this photo.  Not sure I've seen it before.  Too young to have seen the Dead, but I'm so happy I got to see Phil and Bobby several times with various iterations of their bands.

    May the(ir) music never stop.

    Need I mentions the other “benefits” of this crap Pattern—

     

    Heating bills up

    ice melt use up

    slips trips falls up

    doggy depression up

    boredom up

    Friendly counterpoints:

    Heating bills up

    -solar & electric FTW

     

    ice melt use up

    -Wear yaktrax or tell your DPW to make sand and salt mix available like civilized towns

     

    slips trips falls up

    -See above

     

    doggy depression up

    -Tell him to suck it up and give him an edible

     

    boredom up

    -Pond hockey every weeknight and ice fishing every weekend.

     

    Adapt or die (from this trash pattern), I always say.

    I've been contemplating making an AI bot account to automatically post the tldr; versions of your posts.   I wanted to test out of it would have the desired result and the initial attempt resulted in a text body even longer than yours.  AI still has a ways to go it seems.

     

    The short version (TL;DR)

    He’s saying:

    A major, fast, and violent pattern change in the North Pacific around Jan 6–8 is likely.
    That change will probably force a stronger-than-expected ridge in western North America, which in turn means models are likely underestimating how amplified (extreme) the downstream pattern will be over the eastern U.S. around Jan 7.
    Bottom line: don’t trust the details yet — bigger swings are favored.

    Now let’s unpack the jargon.

    Line-by-line translation

    “I think we need to consider the 6-7-8 a pattern arrival event”

    ➡️
    Around January 6–8, a new large-scale weather pattern is expected to fully arrive.

    Think of this as: the atmosphere reorganizes itself rather than just day-to-day weather noise.

    “That's going to be an H.A. implication (I suspect…)”

    ➡️
    “H.A.” = Height Anomaly (upper-air pressure departures from normal).

    He’s saying this pattern change will strongly affect upper-level pressure patterns, not just surface weather.

    “all ens systems agree in the rather abrupt guard change in the N. Pacific”

    ➡️
    All ensemble models agree that there’s a sudden flip in the North Pacific pattern.

    “Guard change” = the atmosphere switches roles quickly (like defense → offense).

    This agreement is important — it means the signal is probably real.

    “The entire circulation medium out there essentially product reverses”

    ➡️
    The whole North Pacific flow flips (ridges become troughs, troughs become ridges).

    “like on a temporal dime… Really fast… intra-weekly time scale.”

    ➡️
    This happens very fast, within a few days, not weeks.

    Meteorologists don’t like this — fast changes break models.

    Why this matters for forecasts

    “that's likely to cause increased model performance problems”

    ➡️
    Models struggle when the atmosphere changes this quickly.

    So details beyond a few days become unreliable.

    “sending such a violent signal downstream”

    ➡️
    A big Pacific change ripples eastward across North America.

    Weather patterns behave like waves — a hard shove upstream creates chaos downstream.

    “the western N/A ridge will be in a period… correction vector… toward more amplitude”

    ➡️
    As models adjust, they will likely correct toward a stronger western North America ridge.

    “More amplitude” =

    • higher ridges

    • deeper troughs

    • bigger temperature swings

    • more extreme outcomes

    “more than is currently in the cinemas”

    ➡️
    Current model maps are too tame.

    Reality is likely bigger and sharper.

    “wave # number/distribution argument”

    ➡️
    This is deep meteorology, but in plain English:

    The way large planetary waves are rearranging forces compensation elsewhere.

    If heights crash in one region, they must build in another.

    “supplant the regions N of HA with… height anomaly reversal”

    ➡️
    When upper-level pressure drops hard in the North Pacific, physics demands that pressure builds somewhere else — in this case:

    ➡️ Western North America

    “there will physically necessitate height growth into western North America”

    ➡️
    A strong western ridge is basically unavoidable.

    This is the key sentence.

    Why New England should care

    “More than 50%… closer to 80%… takes place in < 5 days”

    ➡️
    This is an extremely rapid atmospheric reorganization.

    Which means:

    • Models haven’t “caught up” yet

    • Downstream details are suspect

    “I would be reeeally leery about any depictions down stream over eastern N/A”

    ➡️
    Do not trust model specifics for the eastern U.S. yet.

    Snow vs rain, cold vs warm — all still very fluid.

    “more amplitude is actually favored”

    ➡️
    When things settle, expect bigger extremes, not moderation.

    For New England, that usually means one of these, depending on timing:

    • Sharper cold shots

    • Stronger storms

    • Higher snow potential or sharper cutters

    • Bigger pattern swings overall

    “That all times around the 7th for some sort of emergence E of the nations midriff longitudes.”

    ➡️
    Around January 7, the effects of this pattern change should start clearly showing up east of the Mississippi.

    That’s when things “pop.”

    The Big Picture (in normal human language)

    He’s essentially warning other mets:

    “Hey — the Pacific is about to flip hard and fast.
    That almost guarantees a stronger western ridge than models currently show.
    Because this happens so quickly, models will struggle and probably underplay how extreme things get downstream.
    Expect bigger swings over the eastern U.S. around Jan 7 — and don’t lock into specifics yet.”

    If you want, next we can:

    • Apply this specifically to New England snow/cold odds

    • Decode what this implies for storm track vs cold supply

    • Or compare this to past winters with similar Pacific flips

     

    Before you respond in earnest, I'm half joking.  Always read and appreciate your insight.

    I think we need to consider the 6-7-8 a pattern arrival event 

    That's going to be an H.A. implication ( I suspect ...) as nearing the 5th, all ens systems agree in the rather abrupt guard change in the N. Pacific.  The entire circulation medium out there essentially product reverses, like on a temporal dime when considering planetary wave distribution.   Really fast...  intra-weekly time scale.

    If that happens - first of all - that's likely to cause increased model performance problems.  Furthermore, the implications of sending a such a violent signal down stream, the western N/A ridge will be in a period whence the 'correction vector' will be pointed toward more amplitude - hint, I think more than is currently in the cinemas.  It's a wave # number/distribution argument.   When you supplant the regions N of HA with as much total height anomaly reversal (lowering in this case) like these charts below are showing ( using the GEPs but they are all doing it ), there will physically necessitate height growth into western North America...

    More than 50% ...closer to 80% of this mass field alteration takes place in < 5 days.  I would be reeeally leery about any depictions down stream over eastern N/A. And by that, more amplitude is actually favored.   When I say correction vector that's just an expression I use to mean corrections that are inevitable in the guidance will likely lean in a given  direction... 

    That all times around the 7th for some sort of emergence E of the nations midriff longitudes.

    Were you raining for a while there?

    Short while.  Maybe a half hour?  And even then it was light - only 0.02".  I know the peninsula proper and adjacent areas right (and I mean right, like your place) on the water rained for 2 hours, give or take.

    I'm centered 3mi from the water on all sides and that was enough to make a difference.  Driving around during that time, the difference between 35/36° was the line and it was an immediate line.

    I saw that. Some models came west with that, but hrrr seems like an outlier. That’s my only shot I think unless this first piece comes in aggressive which isn’t likely.

     

    Anyways enjoy near PWM. Hopefully lemons grabs 12-18 there. 

    Bullseye of > 1.50" right over me is hilarious.
