Re: ATL: SAM - Models
Mildly interesting to note that (day 4-5) the 12z Euro actually shifted east of the 0z, which got almost to 74W before making the turn.
The (stronger) 12z only makes it to about 71W (E of Bahamas).

That's the problem, one or both of them is getting there by accident, we will see but I'm going with OTS until further notice.
What do you mean by accident?
You cant have two different tracks ending up in the same place and one of the tracks being correct so even though they end up in the same spot the one track is wrong and ended up there by accident.

With that shift east from 0z and the ensembles mostly out to sea, feeling quite a bit better it'll stay off the US this afternoon, I think the GFS and Euro will wind up somewhere in the middle, Bermuda probably should watch it.

Being from Louisiana very glad to know this thing won’t get to the gulf but the eastern side of the US should watch out. Major hurricanes like Ida are no bueno.

Comparing the ECEN / GEFS 12z ensembles... starting to meet in the middle?

Interestingly, fully four-fifths (80%) of the EPS and roughly half (~50%) of the GEFS members show Sam passing through Hebert Box #1.

I don't put too much stock in the Hebert boxes. Andrew (THE quintessential South Florida hurricane of my lifetime, and still of the last 30 years) missed them, and Maria bullseyed #1 before blasting PR but missed the CONUS entirely.

That is true, but then again this is so far out in time that the whole environment can change.

Model Runs Cheat Sheet:
GFS (5:30 AM/PM, 11:30 AM/PM)
HWRF, GFDL, UKMET, NAVGEM (6:30-8:00 AM/PM, 12:30-2:00 AM/PM)
ECMWF (1:45 AM/PM)
TCVN is a weighted averaged

A blend of those would support a storm crossing 20N/60W, which would keep it in an area with MPIs of 915-930mb in the Days 3-6 range.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

It's crazy that 12z GFS and Euro, despite their completely different solutions, both end up threatening New England in the end.
I think that's very concerning if you ask me.
IF this plays out here is my guess on where future disagreements may lie:
The GFS will favor a more Northern New England hit whole the EURO would favor a more Southern hit, possibly getting as West as NJ/NY.

Just for grins...
Kitchen sink of spaghetti...
All operational(Euro / GFS/ CMC / HWFI/ HMON / NVGN / UK) + All Ensemble (EC(#52)/GEFS(#32)) + all consensus aide tracks (TVCN / TVCE / TVCX):
(white is consensus of everything)

Re: ATL: SAM - Models
GFS still has a different solution though it puts the storm in a similar (but still well north) location as the Euro.

The new GFS model has body slammed the ECMWF all season. My money is on a fish recurve based on every model that uses the GFS base data and it's own performance this season.

That's 2 GFS runs in a row with landfall in Nova Scotia. So much for harmless OTS.

That'd be nice but the GFS didn't present an OTS solution.
