    Not enough baroclinicity. These boundaries, even now, are lacking the potential energy they should have with a greater temperature gradient. It’s a little better now. At least the waves aren’t squashed to LA lol. But it’s still not enough to get them to amplify much given a suppressed flow. 

    Now isn't suppression more nina-like because of the tendency toward more NS activity? (I remember at one time in Jan 2018 seeing a parade of HP's coming down the middle of the country, lol

    Anomalies still happen. But almost all the snow to our south...and at our latitude lately, comes from getting lucky with an upper level feature to crash temps.  When was the last time we saw a huge expanse or cold powder to the northeast of a low coming across the US?  If the coverage of snowfall overall in a larger scale decreases the odds of any one spot getting snow goes down.   

    Define "lately"...Just this year, or did you see something between 2016 and now? Again I'll mention the "bomb cyclone"...lol

    Yea if that setup doesn’t “work” I’m not even sure what we’re tracking anymore. 

    How do we know this isn't unique to just this season, though? You mentioned yesterday about the PV pushing cold to the other side of the globe and the fall torch...how do we know that's not what's doing this? I mean...It still snowed in the 2018-19 winter, didn't it? How do we get snow in the south, and even the January system that year, if the overall base state is bad? And with last year's +++++++++++AO...can we even count that year? Lol Maybe I'm thinking about these things too simplistically, or maybe I'm just looking for optimism, but...I'm just wondering.

    An inch of ice accretion is highly improbable. Of course it’s not impossible but unless temps are well below 32 and rates are light I just can’t see it. Obviously if it looks like this Sunday you’d have to start prepping for the worst. I was supposed to be in Winchester for a dentist appointment Monday and to visit my mom but 4 hours on the road with all this potential ice, I’ll probably cancel. 

    Wait, so lighter rates of freezing rain cause things to be more slippery than heavier rates?

    It was an improvement from 0z. The track of the upper feature is perfect.  It dies but follow the precip associated with that and it’s headed right for us. Problem is it was too weak. But that’s not some huge change. It needs to be slightly more amplified with that exact track. The surface low is a response to arhat upper low do don’t worry about that. If that upper feature was stronger you get a stronger more tucked surface low and that precip coming from the west doesn’t die. There is a critical mass type level of amplitude the wave has to reach and this run was just a bit under it. 

    Now I was wondering if it was an improvement...because that run a bit of snow still got up here, right? I thought that was still better than 0z as well...but I thought it was just my snow weenie brain trying to find something, lol I guess tonight's 0z is gonna be telling if we see the euro trend better...

    Notice...the GEFS have not shifted that NE wall to the precip running through central NJ at all the last few runs...but are tightening up the precip south of that line.  That is about what I expect in the end.  Somewhere between Philly and NYC is going to be a very very sharp cutoff and south of that gets a good snow and north is smokin cirrus 

    So could you explain again your confidence that the cutoff sets up there and why it's less risk that it sets up south of us?

    I know this sounds contradictory...but imo its all about the health of that upper level system in the Ohio valley.  If that is amplified enough I do expect some north adjustment towards gametime.  But I bet it goes one way or the other.  If the upper level wave is too weak and starts to shear out this will trend south...and end up not even that close.  If it is healthy enough to pump ridging in front it will amplify enough that it will trend north SLIGHTLY.  So long as its not a shearing out mess as it comes across my bet is it trends slightly north...but this isn't a setup that argues way north...if DC is being fringed we are good...if richmond is being fringed...uh oh.  But I don't see a close south miss with an amplified wave to be a high risk...this is either going to wash out and be a weak NC system or amplify and we are good.  

    I'm psyched with one of those scenarios and good with the other. If we can't get it I'd rather south not get it either, lol
