Going back to last year, the Euro has consistently erred by overdeepening surface lows along the SE coast at this range. I remember seeing the Euro spitting out 940 MB lows over hatteras last year. The GFS seems to be more accurate at low pressure strength at this range while the Euro is quite a bit better at locating the storm tracks at this range. At least that's my impression from watching these weenie fantasies evolve over the past two seasons.

yea, the Christmas storm last year was a Cat 2 hurricane pretty much on the Euro from this range

Weve been there before with the euro. I mean I'm not adamantly writing it off like past storms but let's not read things that are not there.

just stating that the Euro and its ensembles are in agreement with an amplified solution, while the GFS and its ensembles are in agreement with a flat solution. not sure what you see that's not there?

im just saying i dont think it's that meaningful that the euro ens is not flat.

fair enough. I think it is important, at least in the argument of amplified vs. flat in the day 6 to 8 period. the fact that we're in the sweet spot on the last two runs of the Euro is not important...i think we both can imagine a number of ways that an amplified solution can go wrong.

i suppose. it just seems in other instances of the op being overamplified the ens was as well.

the Euro has had a monster trough in the east now since the 12/24 12Z run's Day 10

if consistency means anything, idk, sometimes "yes" and sometimes "no", but ya' never know if this time it's a "yes" until after the event :axe:

i dont think it's cut and dry that it wont happen (though it seems unlikely it would happen as 12z shows)... but in a convoluted scenario it's hard to imagine the best case scenario. plus i dont think it's a lie to say the euro has not had its best times over the last 2 cold seasons even if it still spanks most of the other models overall.

there are instances where that has been true, but that's expected because the ensemble can be biased to the ops (e.g., sometimes it is difficult for them to have radically different solutions), especially if the reason for a poor forecast is related to something in the initial conditions/model physics.

however, in this case, the Euro has been steady in showing amplification for several runs now, but the same could be said for the GFS who has had consistent flat solutions in both the ops and ens.

large scale pattern changes are typically poorly forecasted....maybe reality lies somewhere in between the two. I just like having something to look at again, i was getting a bit bored at work, being productive and all, during this terrible pattern.
