January Medium/Long Range: A snowy January ahead?

It's a crazy delicate setup. It's looks like the NAO block/ridge is partly what forces that energy to dive S and phase it on the gfs op. Ridge out in the Pac NW also  ot as quick to break down/rollover whereas the models that aren't phasing have a weaker NAO look or degrading faster and also the Pac NW ridge essentially progresses and rolls over. The latter scenarios allow for more of a kicker to nudge development too late.

Said it earlier, even tho the GFS op is wx porn, there isn't much wrt realistic pattern progression that would support such a scenario.

Still feel this setup favors you guys in the  Mid Atl for a light-moderate glancing hit while the storm get nudged ENE while developing. Dont see the KU DC-NYC with this setup.

For that statement to be true I need about 5 more inches of snow this afternoon.

Yeah, I was a bit surprised this morning as well.  Even LWX was saying 5-10 eventually - though in all fairness, if I pick up another 2.5" this afternoon, I'll probably be at 6-7". I suppose they hit lol.

Areas to the south really did perform better - I don't know if it was the dry air (LWX got that wrong, onset was about 2-3hr later than expected for me) for areas north, or what.. either way, it seems to jive better with what the Euro was showing.

Im not sure, other than phasing earlier and a less positively tilted trof, what mechanism is in place to bring this N. This setup is another that favors DelMarVa and points S. So some of you folks will find yourselves in a good spot again. Has some potential down that way. However, I do not see Chuck's warm forecast for Jan 11 and rain playing out. Most times I agree with him even tho I dislike non-cold and non-snow, but this time he's off :oldman:

yea I don't know what he is on about right now... his intricacies aside he is usually really good at pattern recognition but right now he seems keyed on one specific thing and not factoring in the whole pattern.  Maybe because recently that one thing, specifically the N Pacific around Alaska has been driving the bus...but in this case I don't think so.  That trough under it is very different and creates a different downstream reaction.  The pattern all around it is very different, and a full high latitude ridge bring that ends up extending into the north pacific is not the same as the -PDO driven pattern we've been in.

UKIE attempting something CMC-like, not sure if it will turn the corner at all.

Energy gets buried in the Southwest. The northern stream energy races out in front and leaves the southern energy behind. We need that phase to happen for it to turn the corner.

That said, this is a little better than 00z, so there's that.
