Perhaps the models changed as a result of being initialized with a tropical storm instead of a wave?

I would expect some future runs to shift back just north of Tampico *if* Harvey struggles some in the Caribbean> Be interesting to hear WXman57's take on the new runs..

Well the ULL heading for Texas is predicted to make the steering complex after day 5 because if Harvey and the ULL are strong enough the steering will be zero and it would stall for while ! Near the Yucatan maybe in the Gulf or BOC

The thing is it is becoming a trend ! And it's not a good one for now

I remember your post last night, telling me that the future in the GOM might still be uncertain.

Yeah so many factors at play here and the models are lost as of now this pattern is really hard to predict the Strength of the ULL will determine alot and also will the strength of the Trough diving down in 7 days !

now GFS has come in a lot stronger. However, HWRF is coming in much weaker

Safe to say if upper air pattern is conductive the TCP in he GOM could bomb out Harvey...very warm untouched water.

A good amount of EPS members still take this into Mexico, so get the windshield wipers ready.

One run in a bad model year. Euro had Franklin go north as well before settling into the more southern route.

Um in 2008 the Euro spit out a run into MX instead of FL...this was Sept..all models were dead set on FL and they finally converged. I knew then the high would not hold in mid Sept so force a MX track. We all know where that ended up.

When the Euro speaks I listen. Expect the remaining model to continue the trend north today...

The high isn't going to just sit on us it's going to move I expect that change to happen, climatology my friend!! So this euro run could be a trend

No offense Rock because I enjoy your posts, but I have access to 5 meteorologists, and all currently are not concerned with Texas. Yeah, I absolutely know that can change, but there's nothing at all yet to indicate an alarm sounding for Texas. Like you, I love the Euro, but it and the GFS have been hot garbage this year.

Caveat: Yes, Harvey does have me paying attention more than I normally would. :D

Oh an this is why--- Avila: "The GFS and the ECMWF global models are just a little more enthusiastic in keeping the cyclone from dissipating in this last run, but who knows what they might forecast the next time." :lol:

only 5? :lol: and they are not concerned at the possibility of a TC in the GOM in 7 days? I don't know about you but that possibility, for the common amateur weather dude like me, is concerning. Especially when the EURO is sniffing. GFS is garbage this year which in post verification it will show the EURO crushed it this year.

Every model has trended North slightly especially the HMON and HWRF
The HWRF shows Harvey moving NW towards northern Mexico or south Texas!

Five, yeah, but really I only talk with one about 20 times a day. :lol: So far, no. Their thinking is that the models aren't handling what is an overload of weather data, along with 92l out there and the potential interaction. Basically, they think that there's way too many factors right now, so the uncertainty is even much higher than it normally would be, even under ideal model circumstances. I've not seen so much distrust in models like I have this season, and that's with over 15 years of this in my background. Doesn't mean they aren't paying attention though, and you can bet if we see another two Euro runs like that one, they'll be a little change in tone. :D

Not sure how long it will hold up (or impact Harvey eventually) but man ... that sure is one big TUTT low moving west through the Florida Keys right now!

I wonder if they are inserting a synthetic vortex that can be better resolved by the model? Maybe that's why it is able to handle the storm after genesis


From my understanding they use IBTrACS for active tropical cyclones, but I'm not sure how the models use that data.

And now let us inject Dr. Neil Frank, who has forgotten more about tropical cyclones than most of combined, always be vigilant. Never give up watching until a system is dead. ( Wxman 57 stated that too). Never let your guard down. He stated anywhere from Mexico to Louisiana should pay attention to this. When the NHC watches/plans a track on SHIPS as opposed to Euro/GFS, then that speaks to what Soupbone said. They just do not trust the models. Very quirky year. :)

Spread continues..waiting for Euro later today and see if it sticks to last run or somewhere around the same area. When in doubt always go with the EURO.. :wink: it usually picks out a trend first then others follow. 08 was a prime example.

The eventual track is usually somewhere between the Euro and the GFS.
