Tip brings up a good point with the NAO. It is very positive. And forecasted to only go more positive. With the NAO set up like it is, how can this system not come north a bit. It is taking a track as if the NAO were extremely negative( a la 09-10). So honestly this system should finish being a little further NW than modeled, but probably not enough to affect us region wide. The Cape and possibly the south coast could be affected by this, but nothing to significant.

Strong confluence from the northern vort at H5 is screwing this up for areas away from the S coast. Want that to dampen out or move north.

nyuk nyuk - pun intended?

anyway, I suspect the Euro run holds serve on intensity from the 00z run, but may tick NW some ...

Ya I know. But logically it still has come NW right? Even if it is just a little bit. I still want to go and wave at this thing as it sails by. So you can see where my expectations are.

yup were numb

as phil collins sang "i dont care anymore"

:lmao:

It's a good thing it digest the G4 data or it would have been really terrible ;)

Right!? Man, imagine if this thing really did wind up being a MECS for the northeast and NCEP continued to claim errors? That would have been a hoot. Oh well, we'll see what the relatively steadfast Euro says at 1pm.

You have to wonder if the data ingest actually caused some of the problems. The GFS isn't the best model in the world, but it's not usually this erratic inside of 72...and in this case the errors were all very short windows...0-36 hours at 5h.

It looked a bit slower than 00z but not too far from it. A little better than 06z, but I didn't expect these to be 100 miles nw of the op or anything.

no i certainly didn't either. yesterday had several members on roids which gave me pause that perhaps the op was on to something, but those seem to be just about gone. maybe 1 or 2 members are a bit more robust but i'd wager a lot are scrapes at best.

Yeah, you'd think the data ingested and model physics could somewhat handle the barrage of s/w with the first 24h of the run...if this doesn't play out, it'll again show how the Euro is just overall better. Poor America :cry:

I don't expect the euro to change much today either. We are definitely converging on a solution that may be just a bit too far south, but being 84-90 hrs out..we've seen changes before, so we need to be aware of that. You guys down there are certainly hoping for every 10 mile shift.

the thing is though...yesterday we were still what...120+ hours out?...and the GFS is run 4x / day. if it were only run twice, it would just be a blip....just one day at 5 days out when it amped up a bit too much. the euro amps up storms all the time and shifts around like crazy, it just has a tendency to do it a bit earlier before settling in to some consistency...like days 6-10 it loves to go nuts.

But the GFS errors were at h12 and h24 and then propogated out.

That's unusual even for the GFS.

Yeah, by those terms it only really had it for 2 runs. Makes sense. Still though, the Euro was really steadfast with its handling of all these s/w during the last couple days and if it came down to it, I'd take a model who jumps around at d7 over a model who jumps around at h90 any day of the week. (no pun intended).
