The High Pressure Ridge of Death ate him. Literally at him. At S2K, the thread is both funny and sad at the same time. 2011 was a year I want to forget, meteorological wise.
Lol yea that is definitely 1 year I don't want to experience ever again. It was unreal watching that storm just dissolve like it did.
Josh Morgerman's chase account of Don is an interesting read - especially this part:
"Cory's and my experience on the ground suggests that the system's disintegration might have been even faster and earlier than operationally believed."

I was wild, funny, weird, strange, illogical, unbelievable, all at the same time. I reread the thread. The disbelief from you, me, Porta ( and a whole host of others) was just, well just. We were all wanting just some rain that year. I think by the time Don was done for, as it were, our last nerve was frayed to be honest, Jason

lol You can't really blame "the system." Don was brickwalled by a biblical Death Ridge.

The fires near Bastrop. Young red oak after red oak in our yard biting the dust in 2011 or from the stress over the next 3 years.

Speaking of the Don thread - there are so many posts on there that in hindsight, read so differently now.

One that stuck out to me was on 7/28/11 - that night before landfall and everyone was going gaga over a suddenly intensifying Don, and it looks like my post was the very first one to rain on that parade and mention the dry air:

Could we have a similar issue with TD#14? Something to keep an eye on.

We all eyes on the tropics I see we may have some storms today. Areas just to the NW, W, and SW of Houston have a marginal risk of severe thunderstorms this afternoon. From the SPC:

...Southeast Texas...
Isolated to widely scattered thunderstorms should develop near a
weak boundary this afternoon. With ample moisture/instability and
upwards of 2500-3000 J/kg MLCAPE, thermodynamic profiles appear to
be conducive for the possibility of a few wet microbursts with
potential for localized wind damage

12z hurricane models stay roughly the same. Hurricane to central Louisiana.

Of course the HMON marches Laura across the gulf towards Texas or Louisiana.

And let me be clear about the hurricane models. They can often overdue a storm on intensity and sometimes be outliers but they are big tools in modeling guidance for the NHC and why you will often see them in the discussion. They can't immediately be dismissed.

I don't recall so much chatter and model interests about a system that doesn't even have a name yet. Should be an interesting 3-4 days ahead.

12z HWRF has a cat4/5 heading wnw towards central Louisiana/upper Texas coast towards the end of it's run.

12z Euro initialized correctly. Beginning to be more interested in if it starts lining up with what the hurricane models are showing for Laura.

The possibility of two storms in the GoM at the same time is pretty crazy! And it is 2020 after all. :shock:

This is Laura correct?

Lo and behold the 12z Euro is tracking Laura similar to the hurricane models though not in intensity. This is a little insane.

13 is heading towards the lower and mid Texas coast as a TS.

Sorry. 14, or eventual Marco towards the mid and lower Texas coast.

Big change in the 12z EURO showing a landfall around Corpus Christi.At least this time it looks like this storm will be lopsided to the north and east of the center due to shear instead of to the south like Hanna was.Which would allow much more moisture than what we got with Hanna,but the flood threat would increase as well though. GFS may been on to something.
