    Can't account for micro nuances like that though. I think the trend E was real and things just materialized a little south.

    Can it account for micro several year periods of 20% or greater snowfall deficits? Ir is there a line of bullshit to account for that?

    It’s definitely all about the convection. Those uglier RAP runs and HRRR runs are chasing. We’ll know how real it is later this evening. 

    IMHO, if guidance is still reversing trends this late in the game, its simply going to be a nowcast aspect that models can not resolve. This doesn't necessarily mean it works out favorably either...its not a weenieism to ignore unfavorable trends, but rather an acknowledgement that if it's not resolved at 10 hours lead, then maybe it won't be.

    I liked 12z better...if this continues, fine...but this provisional solution is not as good for me.

    The QPF on the N end is compressed more, but the heavier echoes are tossed more to the south....if the H7 low closes fast enough, this will be be fine bc mid level banding will have higher totals north of QPF, but if the mid levels don't get going fast enough, its a slightly worse solution for northern folks.

    The dual low structure eventually gets gobbled up into one main low on all guidance....but where that happens is key...if it happens sooner, it really prolongs the heavier snowfall in SNE and that would mean we have to up the amounts....if it happens much later, then it keeps snow amounts more adivsory/low end warning (in eastern areas) most likely.

    That is what I noted to scooter with respect to the GFS speeding that process up at 12z...NAM slowed it down.

    should I subscribe to weathermodels.com or f5 weather? on the fence between the two now

    If you value more accurate snow maps, F5 weather...if you just want better overall graphics, then weathermodels.
