Tropical Major Hurricane Laura

Looks to me that the different results in Icon and Gem is the Icon is riding just a tic north at 60w.....
 
An area of low pressure located about 1300 miles east of the
Lesser Antilles is producing a concentrated area of showers and
thunderstorms. Environmental conditions are conducive for
development, and a tropical depression is expected to form within
the next couple of days while the system moves west-northwestward
at 15 to 20 mph across the central and western portions of the
tropical Atlantic. Interests in the Lesser Antilles should monitor
the progres of this system.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

12Z Euro through hour 120 very weak so far/open wave likely headed to GOM.

Great news so far.

Thoughts on why Euro isn't developing it?

Well, the model is smarter than us and is the King. So, I'm hoping like Hades it is on the right track. Keep in mind that the GFS is also weak. The HWRF being strong is no surprise as it has that kind of bias.
The Euro isn't weak due to shear, dry air (dewpoints are 76+), or cool SSTs though there's land interaction later.
What I'd give for this to end up a bunch of nothing!

I'm with ya.....reading other commentary, many are going hmmmmm.
 
I'm baffled as to why the globals are so meh

Like I get being hopeful but for me it doesn't make much sense realistically
Saharan dust? Shear?

Agree. But like I said yesterday, so far everything has been kind of a mess this year. You'd think we'd see a more robust system. I think we will, especially, if we're not seeing dry air, shear, or cool water. Wonder how instability looks down that way?
 
Saharan dust? Shear?

Not shear as it is very light. Can there be SAL with high dewpoints? If so, perhaps SAL??

So far, the 12Z EPS is very quiet thus in agreement with the op thru hour 108+.
 


Perhaps this competition will keep it weak and may be why the Euro and GFS are weak?
12Z EPS, like the 0Z EPS, is vey quiet through 132 with only 1 of 51 at TS+ strength!
Later as it gets to near the E GOM, it develops some members like the 0Z did. Also, there are a few weak members off the SE coast with one nearing H strength as it passes just offshore the NC OB.

Strings out the vorticity and fast movement. Likely competing circulations within the trough.

Sounds similar to the way Isieias formed. Took a while to figure out which area would develop and that is always a problem for early modeling to pin down which sometimes will effect long range results.
 
Looks to be getting its act together in the latest vis loop.

Bad for the Carolinas as it stays weak off FL coast....will be interesting to see if Euro moves to East coast tonight.

12z Navgem....interesting

Not that the navgem needs to be taken seriously as it's not best but the difference IMO between it, the icon, and ukie is a stronger storm earlier and further east COULD cut down on impacts to Florida and offer an earlier and cleaner miss off the east coast versus a scraper like the gfs had.

I agree.....I watch it only for consistency to see if it aligns with others. Euro tonight will be interesting....if it moves east.
