Re: ATL Invest 91L: Models
Who needs model support these days anyway? A week ago or so only GFS showed anything of significance brewing this upcoming
weekend. We've seen the models lay eggs many times before in the past in both extremes so nothing surprises me. IMO

Hurricane Bud, perhaps..was it not forecasted to be a Cat 1...was it not a Cat 4 at one time?

Re: ATL Invest 91L: Models
UHH I witnessed first hand.... All the meterologists saying Harvey will only be a strong tropical storm for Texas... Then it was oh it could make a run at cat 1 strength... few hours later this thing is getting its act together quickly maybe a cat 2 or 3 at landfall... final outtake Cat 4 landfall... so anything can happen we have no control over it at all... oh and to add it was only 300 miles off texas coast when they were saying these things...

Never trust the Gulf!
Not that every storm down there will blow up into a major, of course, but I've seen quite a few of them pull such surprises. I remember almost expecting Katrina to become a Cat 5.

Re: ATL Invest 91L: Models
Looking at the early deep level steering it appears they expect some ridging to be in place over the northern gulf? On the other hand if this remains a sheared system and moves fairly quickly inland maybe there won't be a lot of 7" plus rainfall totals?

It did only to relax back to Cat 4/3 landfalls with Cat 5 type surge. I don’t see 91L getting super strong but you never know for sure.
All major MJO guidance gets to Phase 2 in several to ten days. Could be a lot of instability around the SE for a few days regardless of 91L. It will be cool to see how it plays out this weekend into early next week. JMA is most direct and quickest to get there. NCEP’s forecast is fairly close to JMA model touch JMAN for output).

Re: ATL Invest 91L: Models
Latest 00z Euro Ensembles are slightly more bullish but still look hostile for much development if any at all.

The ICON model is drunk. It keeps the low off Texas coast until Tuesday and slowly strengthens it...

ATL: Invest 91L - Discussion
@RyanMaue
Seems the experts that were warning about the GFS "false-alarm" hurricanes in the Gulf of Mexico were right. Or, you could have just looked at the answer key. (e.g. ECMWF)

Maue and his horn tooting are getting annoying
How about he explain the clear phantom his favorite EC spewed off of the East Coast
