Right near where we’d want to be at this range. Nice event.

I’ll take it. Low actually tracks a bit inland but that cold high keeps areas N/W of 95 frozen. Plus the model trend is faster handoff to the coastal.

I dont know much about nothing.. but something tells me temps will not be a huge issue with the placement of the high and the blocking pattern that is setting up.  It seems like temps come colder when we get a block... Dec 2009 was a great example of that..

It’s only a hit depending on where you are.   

Yeah as always. I know I’m not going to lay money on the cities and close in burbs being all snow for this event, if it happens. But a lot of things to like for some snow for many of us.

That cold high is why it’s as much frozen as it is. Still too much OH valley low and the 850 low tracks over us or even a bit north of us. That’s not a recipe for 100% snow. Need to kill that thing sooner. But that’s the trend today so far for the gfs and GEFS at least. Hope Eps follows.

It’s easy to get caught up in the verbatim but you look at the players on the field and there’s no way I’d want a scraper look 6 days out with that blocking in place.

Give me wiggle room if that high is analyzed stronger closer to game time. 

Let’s just keep this looking like this for another 60-72 hrs and then hope we get our usual CAD pregame help.

I remember 2003 was initially forecasted as a snow to rain event of days out.. and then as we go closer and closer to the event.. temps got colder and colder

Yup.  Just one more tick south and we're all in the game.  As it stands now, I get a bit of snow.  This far out in December, not sure what more can be asked

SLP and 850mb storm track is actually a little better on the 0z euro vs this run. OH valley low hangs on a little longer with a slightly farther north handover and inland track at 12z. Just that high is more potent and we have a much colder airmass to start. Both are very small details at D5-7. 
 

Take the 12z high pressure and the 0z low pressure and that’s probably ideal for the metro corridor.

Why does the storm seem to move so quickly? I thought a nice block was in place? Other than that, like the look this far out. Hopefully it trends in our direction.

Blocking isn't set in place. Per the indices posted on Pg 34, we're still lining everything up. The window from 12/20 to 1/1/21 is where you'd possibly see something crawl and slow down. Typically you need to see a big ridge over Idaho as the wave crests the GOMEX for it to really torque and slow down, a la 2016.

I dont really know that much about this.. but I think when you get HP to our north with a blocking pattern in the atlantic and a developing storm to our south... it forces cold air in to our area.. 

I agree with this. With a -AO and -NAO tandem in place, things generally tend to trend better or at least hold course rather than the opposite. Haven't had this setup in quite a while. Definitely an eyebrow raiser.

Exactly...essentially what I'm thinking.  And even taking it verbatim with the (silly) snow maps, I take heart in the fact that a couple inches still gets into the cities, with a bit more where I'm at on the northwest side of town.

As has been said, get that primary to transfer sooner, rather than when it's up near the OH River, and a lot of people would be quite happy (with the possible exception of Ji, hahaha!).  I haven't really been looking at this in detail until just the past day or two, but has the transfer of energy trended one way or another over time?

Yup. Last year the pattern change was always modeled to be D15 and it got stuck there.

Storm movement speed is never going to be accurately modeled at range.
