When the NAM in a situation like this has you just about 100% rain... you know you're screwed.

Gees man, with this nam run im not even sure the highest peaks in Litchfield County can pull off an inch...I was predicting 1-3 there yesterday and 1/2 - 2 in the high parts of the tolland area..probably back off to a coating - 1.5" and slushy coating respectively with my update. Nothing but a little tail end mixing elsewhere in your state

Mentioned that this morning...could amp up the ridge just a bit.

Possible, ...though less than certain, the NAM is keying in on that subtle feedback and that causes the low track a tick NW as it rides over said feedback...

Also, one thing that folks should think about is that this is the first system this year with a bona fide polar high parked N - this is not exactly a needle threader. That distinction of this is incorrect because of that cold factorization.

This is a bit of uncharted water, in the sense that we may be rusty to recall that busting on the cold side has greater probability than not having that polar exertion present at all. The 850-1000mb thickness did edge slightly warmer in CT, but N of the CT/MA boarder that means little for this event. Light to moderate UVM rates combined with initial, conditionally cold atmospheric thickness, combined with having the source from that polar high should ensure that whatever falls will be frozen. As for CT, I would bet that rain start pinging mid way through and ends as an inch on this run, then flurries and grains lag into for several hours - it will transform winter. Don't have to have a foot to tone the appeal that way... although I understand that if the pattern isn't ideal, everyone crows and posts negatively.. but that's another story. Anyway, this is just one run of the NAM

Your in a great spot right now... :snowman:

He always is....it's been like a protracted showing of the movie "Groundhog Day" for the better part of the past 5 seasons....

1) Looks great for most of SNE....MPM laments QPF...Scooter consoles him with tales of the mighty mid level features.

2) Looks like Dendrite and MPM got invited to the QPF party, afterall....still looks good for alot of SNE, too.

3)Congrats, Dendrite....where the in the fu** is my toaster.

:lol: I heart you man. I remember growing up in Rockingham County and often being progged to get mostly snow and decent QPF, but when verification time came I was always pissed when I saw the higher totals end up to my north. I've definitely been on a lucky streak, but it all evens out eventually.

When I'm smoking cirrus and you're raking up 25" in a HECS from a coastal front you won't care about the 3-4" I get from a putrid SWFE. :)

You summed it up quite well

The NAM sucks for many south of ORH and even them. What a POS model in general.

I don't know what to think. I do think that nrn ORh county at 1000ft back to GC will do pretty good. 2-4" with maybe a spot 5". ORH seems to be closer.on the fence. I think the Monads and into CNE will do well someone will get 6" or better. If the euro holds serve..I'll would feel better with those amounts (although I don't forecast there anways), but I have this feeling of something bad happening all the way to I-90. I hope not..and hopefully ORH gets 1-3 or something. My worry is that a lack of ageo drain like you said could screw many. Just not a big cold push south. Also, I'm a little worried it might be a 6hr event where most of it is wasted on trying to flip to snow and the last hour or two are just crappy echoes. The DS could race into SNE near 12z..especially near and south of Pike. But there are a few positives too......If we get a weenie mid level fronto band like some models have, that could help cool the column. My guess would be up in the Berks and near Dave into sw NH..but it could extend a little south too. That may precede the main thump of QPF by 1-2 hrs and help those people out.

very much agree.

i don't like seeing those mid-level RH values coming down near and just before 12z.

Wow...this is toaster bath time for NNE southern areas as well. PWM/CON exactly where BOS was sitting vis a vis BL temps 24 hours ago. Unreal.

That's why I was saying a 6hr QPF bomb that wastes time trying to cool. When it is cold enough..it may only have an hour or so for good steady snows. I could see ORH only getting an inch if that happens, but lets reserve judgment for the euro I guess. I'd feel better if it held serve a bit...but I didn't like the boundary layer on the 00z run.

I know some joked about me being crabby yesterday, but being pessimistic is the way to go. That's how it is this winter around here, especially for you and I. I loathe it.

It is what it is and it give me more time to be more balanced vs obsessing and refreshing every 13 seconds for hours on end.
