12z HWRF is NE of both the Euro & GFS

those last forecast runs at 120, 123 & 126 hours have it going almost due north

NHC latest advisory doesn't show as much of a dramatic turn north as the last advisory

18z HWRF has a pretty large system in the BOC

Harvey continues to battle shear this evening and is tilted towards the SW with height with an erratic convective pattern. Probably not much in the way of strengthening until the shear lets up.

GFS has shifted way north over the last 24 hrs with the 00z moving into S. Texas

Looks like a north trend across all the 00z models so far. It will be interesting to see what the Euro and HWRF do later tonight.

I just looked at the model forecaster and It looks like it shows the storm extremely disorganized until right at landfall. Almost like it gets its shite together in a 12 hour span.

I know recon just got in the storm but Harvey is a mess. Wouldn't be surprised that this is an open wave now but I can see the NHC keeping it a storm since it could strengthen in the Western Caribbean.

Harvey looks really bad this morning and might have opened back up into a wave. That would tend to favor the faster more westerly solutions and would make it hard for it to get very far north, given the current setup.

The 00z Euro and 00z/06z GFS are both good for those areas in Texas that need rain. A lot of the moisture associated with Harvey's wave pouch ends up in Texas and it combines with a front to produce widespread rain.

It will be interesting to see what they do, it appears the system has decoupled based on 12z 500mb analysis

ETA: recon probably found enough to justify keeping it as is.

What do you think that system out towards Florida is going to do? Weatherman I saw yesterday said something it's likely not going to have a huge impact on Gulf due to it likely getting demolished. At worst, probably a big rain maker.

The discussion was like, "yea, it's not really a TS but maybe there are some TS force winds out there..."

The setup has never really been favorable for that system to develop. Look at this post for a bit more detail on why 92L had issues and why the models are struggling with the future track of Harvey LINK
