ATL: DON - Remnant - Discussion

[Dave]

Want some help on obs? Mark down July 29 as another dry day....that rain? It dried up before it got here...I'm starting to feel like I live in Texas. Can do obs if you want.

[HarlequinBoy]

WOW. Corpus gets 0 rain whille parts of upper texas coast received 2-3.

Even the rain on the upper Texas coastline wasn't really impressive at all. I know anything is appreciated but even the 1"+ amounts were confined to a pretty small geographical area. Many seabreeze or afternoon popcorn events have bee more impressive (as I'm sure you know being a resident).

Even the rainfall in far S TX is looking kind of meager. The mesocyclone that was producing such generous amounts offshore seems to have dissipated.

If Don had 50 mph wind at landfall then he's hiding it well. Certainly nothing at Corpus or Brownsville to speak of. I see a 30kt report offshore. Recon isn't having much luck finding TS surface winds. Good news for south Texas, except that the rainfall looks a bit spotty.

[HURAKAN]

LOL ... yeah, you can take over the HDOBs!

[ConvergenceZone]

I salute the models!!! Many were wondering why the models were keeping such a weak system in the Gulf, and not forecasting a hurricane like many of us INTIALLY were.

Well, they sure showed us, and gave us a dose of humility, as there's still so much we don't know and understand about the tropics, and
I think Don is proof of that.

You are kidding right? The models showed NOTHING but passing sprinkles when there was a tropical storm forming.

Ivan, I thought someone on here said that the models later latched onto development, but it just took them awhie? If that's not the case, then you are absolutely correct.

Although Don didn't become a cane like most here thought it would, which proves that it takes MUCH more than just a warm body of water to go from depression to Cane....

Total bust on the rain for CC but yes I'm thankful that nothing nasty happened. Everyone here says we're due a Hurricane, its been a long time.
