Looks like it just plows right into CA and dissipates...


well it also has three lows right on top of each other, maybe it doesnt have a good handle on this run, just sayin


This is typical of the model runs. They will vary at times, however the key is watching for particular trends and consistency from run to run. By this weekend, we hopefully will have the clues and indications from the models to see what the projected path will be going into next week.

The 12Z gfs is quite a bit weaker than the 06Z run.

Would that be because it spends more time over land or because of other factors? I imagine having it cruising around CA would obviously not allow much strengthening. Of course, we don't know where this goes after that (or will we, the last mention is that it is sitting in the Gulf of Honduras).

GFS up to 228,

at 162: still has the storm just sitting in the Gulf of Honduras, with what looks like another system trying to form south of Hispaniola...could it be the second system the GFS has been harping on in the past runs


http://raleighwx.easternuswx.com/models ... cal168.gif

Now at 174, the system is moving SE back towards Honduras

at 180, back towards Belize

at 192, starting to intensify with the second system moving over Hispaniola heading north

http://raleighwx.easternuswx.com/models ... cal192.gif

at 204 moving right over the Cayman Islands heading NE

At 216 moving NE towards Central Cuba

http://raleighwx.easternuswx.com/models ... cal216.gif

at 228, moving East of Florida over Bahamas

Highly sheared with Florida getting a few sprinkles. Odd run for the GFS...

GFS really struggling with the synoptics - very strange run.

With a cut off low in the picture..it is not surprising models are having trouble...

That would be correct a sheared mess. I'am all for some rainy breezy weather.

Ain't gonna happen like that. That's a heck of a strong progressive trough. Think its a bit extreme, though close to the 0Z ECMWF. This will change again. :double:

If that trough comes off so strong then I will eat crow but until then, I patiently wait for the N and W trends to commence.

The important thing to take from the GFS is there is going to be a significant trough associated with a cut off low which should pick up matthew…I do think it’s overdone at this point and think the ECM might have the best handle…looking forward to the GFDL/HWRF this afternoon.

GFS run once again looks at odds with quite a few of the other models out there to be honest, I suspect the problem is the GFS buries it into CA and that causes the system to have to start all over again effectivly in the NW Caribbean by which time the combo of the upper shear and the 2nd system messes things up for this storm.

I think though the 2nd system the GFS is trying to produce is highly unlikely to develop, esp if 95L can gain just enough latitude to avoid heading inland...

The truth is though the models are not to be trusted at all with how this evolves for a long while yet...alot of factors will be at play, far more then the likes of say Danielle/Igor...

Those models will be very interesting Cycloneye but I don't think they are going to be very different from the GFS, probably stronger though!

If the system doesn't move too quickly in the next 24-48hrs then the odds of it not making landfall increase markedly as the steering currents slow right down and induce some northward motion.

Good, so Texas is in the clear. Right? Sounds to me like a FL storm!

I agree.....actually based on Vorticity trends currently the area at 66 degrees west is looking nice...it has such an incredible environment ahead of it at about 68 I would say. Some shear is definitely causing some disruption but imo this area is coming together...I believe the NHC will reflect that and vorticity should increase in that area.

I wonder if this becomes Matthew, gets more powerful than the GFS sees and doesn't impact CA, what are track implications? I mean...it's not necessarily like the GFS is that far out because if it takes forever to get itself together it would bring it very close to October and in late September we can definitely see huge troughs with the La Nina pattern.

The game starts with how far north the LLC forms.

Ivanhater, that looks similar to yesterday's NOGAPS 12Z run. Is this a different one today?
