Based on this and what the Ukmet are showing, I think you are right on the Euro......

The uk and to some extent the gfs have another feature digging down sw of Iowa. Really all three are pretty different at this stage so nothing would surprise me on the euro.

At 60 hrs the gfs and nam are on different planets at 5h.

The rgem and gfs although not in perfect agreement - namely I think the rgem would turn into a more robust solution - are in much better agreement than the nam.

The nam is way slower with the main m/l, trajectory of energy coming into the Dakotas is all different...so many things are different/probably wrong.

so per the GFS down here we see a littel front end snow then lots of rain then a littel snow to finish?

the GFS starts out very mild anywhere in the "non-snow" zone which is probably near or just NW of your area. i'm not sure we'd see a whole lot of front end snow anywhere south of that area. verbatim, off the model, we'd get a little fun at the end. but wrap-around / tail ends can be modeled better than reality works out.

edit: should add though that you'd stand a better chance of some accumulating snow later in the game than say my area.

it snows where it wants to snow

:snowman:

It would be nice to get one of these to hit northern VT and northern NY... however, if that were to happen everyone further south and east need to change to sleet (ie Valentines Day or St Patty's Day 2007).

I am so happy we have upslope to compensate for missing synoptic snows, otherwise I'd probably be jumping off the nearest bridge. I still can't believe how we have an 18-20" snow depth yet have missed just about every single one of these storms.

166" of upslope fluffy on the season at the mountain starting Nov 1st (and that's not counting the 38" that fell in October, so true seasonal total is now over 200").

Roughly 80" so far in town, so it hasn't been that bad of a winter so far even with all the synoptic misses.

Yeah that is usually how it works....especially for areas "waiting" for the cold air to drain in at the end. The one thing your area has going for it though over an area to the SW in the M.A. though is that the CCB will likely be going nuts by the time its nearing you, whereas further S its still in the infancy.

I like this. Over here in Lyndonville, we've had about 50" even though every synoptic storm has missed or grazed the NEK.

where do people expect the rain snow line to rear its ugly head, Plymouth,MA east or is the 95 corridor going to get more rain than snow specificlly the BOS-PVD corridor?

If the GFS works out and 850 temps get near 0 or -1C for a few hours, it will probably be very close to BOS and PVD. That will likely be coastal front dependent.

yeah i was thinking about that part...the mid-level lows take a pretty nice track for that. who knows.

the *current* track would actually be OK from a climo perspective...i.e. it would normally be more of a snow to rain to snow type of deal. this thing just has so much warmth attached to it though.

Ensembles are smack dab over the BM.

Jmho and I said it at the time I think the op gfs is too far north for what it presents. Ultimately we shall see, but I like the ensemble mean better. It's also got to have some spread as the 1.5" line shifted east while the .5 went west. Kind of interesting to me that the best dynamics/most moisture got bumped east in terms of the 1.2 line...

Euro...

System isn't done moving around yet and I'm not sold there is a solid trend one way or the other...will wait for the euro.
