Pattern/storm inverted trough thread early Jan


Damage In Tolland

Which one? That low that develops off the US East Coast or the shortwave that gets into ND in about 12-18 hours?

The one out over the Atlantic at about 60 hours...its hard to say exactly which vortmax is forming it as they become diffuse looking before redeveloping out over the water.

Regardless, with so many moving parts, its going to be a nightmare.

i think the 18z nam just kept it weak (996vs the gfs consistently stronger solution)

i'm just hoping the 0z nam doesn't deepen the first SW to 980

Yeah the NAM keeps it more strung out and then let it escape east enough so that it doesn't interfer too much with the main show diving in from the lakes...so we end up seeing a big solution on the NAM and the ETA.

We need to either get rid of that front running wave or slow it down big time....its screwing up a lot of these solutions.

Yeah it retrogrades right back at ME at 980...12z it just scooted progressively on along. There's going to be a lot of frustrating model runs over the next 48hrs.

I non violently disagree..It was the first to catch onto the closer in storm after the NCEP coverup...but it didn't perform any better before that. As soon as it came wes..so did every other model

Not true. The GFS was on its own for a while... I think it performed quite well within the 72-96 hour period.

Man the GFS continues giving CT 6-12 from the Norlun run after run..Why does it have to be this crap model?

It was giving me like 15-20" for a few runs......I still say that foolish thing is not going to pan out (I know it's physically possible, Will).....the storm is either going to happen or it won't......any inverted trough is only going to drop a light snowfall.

See HM's post today about norlun troughs and heavy snowfall

I think people are confusing what I just said, I did not mean that there will likely be a snowstorm, I am just saying that with the models confused in their solutions I doubt it verifies with this solution at the end. I mean we have about 72 more hours to go before the snow starts. So therefore the models are going to continue to struggle with the various moving parts involved. I mean look at the individual GEFS members for the 12z run, is there any consistency in their solutions? I mean two days ago models showed a snowstorm. Why can't they show the snowstorm within the next two days? Easy said then done, but give the models some more time before catching onto one solution. There are many out there in the models, we need to use caution.

The GFS probably did better with the last storm than any other model, especially inside probably 3-4 days.

Do you mean to actually turn it into a real storm again or forecast until then? Or both?
