0z HWRF -
Initializes it where the 2pm TWO suggested the llc may be forming about the eastern tip of Hispaniola. Takes a much more pronounced westward heading once entering the Gulf through 84 hrs. Light on intensity with this run.

It's somehow going to be near 26N by tommorow morning

The timing seems to be off on all the models though. Euro was way to fast with it.Mr. T wrote:Gotta love the HWRF

I'm pretty much resigned to the fact that the HWRF/GFDL are going to be somewhat worthless until whatever possible changes may occur once the the parallel goes operational.

With the Canadian shifting westward to Texas, it'll be nice if the storm actually shows up well on the Euro so we can see what it really thinks...

EURO up in a few......CMC falls in line with its last run....both see something in the GOM in 96hrs that weakens this to a 1009MB low....not much to look at....maybe dry air..I have to agree with the HWRF and GFDL...pointless gidance IMO.... Maybe for entertainment purposes...

0z Euro takes a very weak surface reflection to the Texas coast by day 5, like the last run
0z UKMET very similar
The CMC, Euro, and UKMET all show a Texas hit, while the GFS and its counterpart GFDL and HWRF are way east outliers
sound famaliar?
One thing is for sure though, all of these models do not show that great of an environment in the Gulf once 97L enters...

So what are your thoughts “T”? Tropical Storm at minimum I think. I do think the models have “future Bonnie” to far to the east. Not too sure if I buy into a Texas hit, just yet that is.Mr. T wrote:0z Euro takes a very weak surface reflection to the Texas coast by day 5, like the last run

My thoughts are pretty much unchanged from earlier. The strong SE ridge that has been in place throughout the summer will again flex its muscles and push future Bonnie westward, threatning locations from LA westward...desiredwxgd wrote:

Tonight's Euro defnitely increases confidence a bit
With such a monster ridge across the SE, any model trying to turn this storm east of LA is full of bad granola. That trough you see about to traverse the Great Lakes will have little effect, if the Euro is to be believed.

So having yet again one of those sleepless nights (many in the last few days) I was going through different news studios websites (meteorology department) and came across KBMT Channel 12 (Beaumont). Here’s a snippet from an online article about 97L……” It appears, at this point, that this will be a Texas storm, however better data is expected to give a clearer picture tomorrow [Wednesday].” Rather presumptive? Jumping the gun at this point? Any thoughts?

Keep an eye to the W of the convection N of Hispaniola. The wave axis is moving and some 'lower level rotation' is evident on the early VIS Imagery. The system may be further W than models suggested.

That's Friday evening, though. Note the trof digging down the central U.S. on the map. The Euro weakens the ridge and moves the center to the East U.S. Coast on Saturday, opening up the mid Gulf Coast. I am not very concerned about this system in Texas, assuming it develops.Mr. T wrote:My thoughts are pretty much unchanged from earlier.

Just noticed 12Z models shifted eastward again, barely taking it into the NE Gulf now. Seems a bit too far east.

It will be nice to have an actual center point for future model output. The spin near 20/70 is looking better by the frame. I suspect this disturbance will appear much better (development wise) 24 hours from now.wxman57 wrote: Just noticed 12Z models shifted eastward again, barely taking it into the NE Gulf now.
