NAM was pre-tossed even though the changes it made are well within it's normal strike zone.

NAM may be un-pre-tossed by the time the rest of the 0z suite is in or if it develops a bomb later in the run.

 

 

Don't look like we are going to see any phasing with this run

Stay the course.

 

The changes are a little suspicious in how it develops a separate cutoff over CA this run.  But if that's right turn out the lights Irene, this would be the biggest bust of the Kuro since yesterday.

 

 

lol, Just a progressive wave, What a POS the Nam is, Its sad, Wasted American dollars...............lol

It's the changes it makes inside of 12-18 hours this run that influence the rest of the run.  We'll see fairly quickly if the other models are on board.  A flat wave is a very real possibility but I'd still favor a glancing blow at least over the Cape and Islands pending the rest of this suite.

 

If one looks subjectively at the trends here's what you have:

 

12z --> 18z --> 0z NAM all get worse each run

12z --> 18z GFS worse

12z --> 18z GEFS worse

0z --> 12z Euro worse

0z -->  12z GGEM and GGEM ensembles worse

12z --> 18z NOGAPS same or slightly worse

 

 

4 day NOGAPS rule is if it is within the cone of the other models those models are going to move.  We'll see post GFS, but it won't surprise me if the rest of the suite wanders SE so long as those changes inside of 12-18 on the NAM aren't explained away directly or indirectly by verification errors.

That's why i mentioned earlier, We are going to need to see at least some movement back NW soon

The problem with the NAM in this event could be that the setup is insanely complicated out west and the NAM is horrendous on the West Coast and never picks up things out of the Pacifc very well...of course if all other models are similar who really cares but the NAM may be the monkey wrench guru the next day or two even if the other models come back.

I agree.  The tell will be the 0z run tonight and the model trends of the GFS/GEFS,  GGEM/ENS and Euro/ENS.  If they come anywhere near looking as terrible as the NAM or continue in that direction I think we are starting to see the end game.  The NCEP discussion isn't out yet, never say never on init errors.  To me the whole thing was fried when the cutoff formed.

 

I'll say this before the rest of the suite is out, I think this is a glancing blow at best.  But it's 3 days away and that's subject to change.

The NOGAPS being so far northwest for seemingly ever worried me about a north track, then it came way south last night so I felt we were in business where the other models were at.  The 00, 06Z NAM runs though being progressive last night were immediate red flags to me, you almost never want to see any storm progged to hit the coastal areas be near the coastal areas on the NAM at 78-84 hours, if you see that it often means you're going to see the globals start moving south and east...the NAM loves being N and W late in its runs.
