Re: ATL: HARVEY - Models
The same models that just a few days ago said this was only a Mexico issue....sorry but everything is still only the table until whatever develops is inland. IMO

Don't think there is a chance of a Mexico/Texas border hit, more like Louisiana/Texas border hit.
Maybe after stalling but no model shows this hitting Louisiana first except 1 Euro ESEMBLE member so I'm pretty sure right now it would be safe to say that this is a southern texas system then it stalls and moves towards Louisiana

So the model is saying if is weaker it moves further west and quicker. Jma is pretty similar to the Ecmwf at 72 with weak or no development.

EC going for a sheared tropical storm at landfall. Vastly different from most of the other models

Re: ATL: HARVEY - Models
The system needs to tighten up quickly because it needs to over come the upper level low to the nw and establish outflow. The whole key to intensity is the next 24 hours. It could be either a weak ts or a major cane. Both scenario are on the table with the 00z gfs/ 12z ecmwf solutions.

the models are saying that it's the final 24 hours before landfall that will determine the intensity. Most have a weak to moderate tropical storm until then. The latest EC shows little intensification as it approaches. Looks like Cindy 2.0. Other models show a full hurricane

Re: ATL: HARVEY - Models
euro pretty much has no difference in position at 96hrs, but, as already posted, is much weaker

Didn't see the ukmet posted. Looks like it is the strongest at 12z.

Re: ATL: HARVEY - Models
Perhaps the Euro is thinking the ULL will hamper development and push it more on a westward track?

Re: ATL: HARVEY - Models
I am curious to know why the models aren't showing much strengthening? Shear forecast? There doesn't seem to be a copious amount at the moment. SSTs are in the upper 80s. Just curious to hear an educated opinion on the models keeping it weak.

it's an upper low over Mexico, not the one in the Gulf, that causes the shear

Re: ATL: HARVEY - Models
Looks like the Euro could be abandoning the ENE turn as well at 120hrs.
Edit: I was wrong, heads back to the coast ESE at 144hrs.

Re: ATL: HARVEY - Models
Ecmwf again starting to move east at 144 , could be back over water similar to past 2 runs.

Re: ATL: HARVEY - Models
GFS is probably sniffing out a strengthening ridge over the Southwest...in combination with the strong-ish through making its way into the Midwest that is going to help break down the upper ridge over a lot of the Southeast. Now, whether that happens is quite another matter.

Re: ATL: HARVEY - Models
The Euro at 144 actually looks like it pushes it back southeast because of the building western ridge.
