ATL: ISAAC - Post-Tropical - Discussion

[HurrMark]

And now it is gone, must have been dry air. Damn Isaac, you finally fooled me too.

Still there, just very open to the north. Where did you see it disappear?

[DukeDevil91]

This is my first time saying this on this thread: Issac just showed the beginnings of an eye.

[CopyGator]

Earlier this morning someone said the motion was essentially stationary...is that still the case?

[tailgater]

Even if this isn't a true eye, the core is improving and will probably drop the pressure even more.

What's the lowest pressure recorded for a TS?

Irene was 965 when it made landfall in NYC as a T. S. last year.

I guess I should have narrowed that to GOM or tropics.
I still see what looks like an eye!

[DukeDevil91]

Also, Issac is losing is horizontal lopsided traits frame by frame on IR. It is much, much more symmetrical.

I've been doing weather for over 30 years and I'm impressed with all of you. The science has come a long way and there's still a long way to go but the one thing I'm impressed with is the rapid sharing of knowledge. We didn't have that when I was hand-drawing isobars 30 years ago!

I'm just an amateur but it just blows my mind the kind of technology we have. We're sitting here looking at pictures taken from cameras hurling through space and getting them in near-realtime in stunning detail.

I'm especially liking the rapid 1-minute thing - wish they would make that permanent and do it for all the GOES satellites. But even getting an image every 15 minutes is amazing.

Eye is still there, slightly open to the north, but looking better. See the convection pop up on the eastern and western 'eyewall?'

Recon headed back towards the center now. I'll go out on a limb and say hurricane on this pass. Read the sig though. I am a finance guy, not a meteorologist!!!

[Cyclenall]

Not quite sure how well that eye's going to hold up.

Yeah I have that same feeling, could easily disappear or open up knowing how Isaac has performed. North convection will tell.

And now it is gone, must have been dry air. Damn Isaac, you finally fooled me too.

Its still there at 10:40 UTC, what frame are you on? I don't think its dry air this time, it looks legit.

From recon thread

@HRD_AOML_NOAA
#NOAA42 radar shows #Isaac eye is still elliptical, but major axis has rotated 90 deg counterclockwise and is now southwest-northeast.

[KimmieLa]

Isaac may have an eye like feature, but he has no head. Convection north of the storm appears to be pretty thin. C'mon, Isaac, do what you gotta do and get on out of here. Please stay safe. Praying for endurance for the La. and MS. folks.

Not a met, not even a tired met, seek professional help.

Call me crazy. That 'eye' is moving west.

[rainstorm]

incredible that isaac cant do anything. it became a TS well east of the antilles and has travelled over well above normal sst's the whole time and its still a TS.

[DukeDevil91]

Next frame showing eye-like feature beginning to get wrapped in convection. As soon as the northern portion of is closes up we'll see some intensification.

its only chance now is due west to texas so it has water to work with.

I'm seeing the same thing. http://www.ssd.noaa.gov/PS/TROP/floaters/09L/flash-rb-long.html

its only chance now

Only chance for what?

I think that it will be tough to get much more out of this. Dry air intrusion from the northern Gulf states (not just the dry air already socked into Isaac) tends to keep storms in check as they head close to land (ala Katrina, Ivan, Opal, etc.). We might see some of that as Isaac gets closer to the coast.

[HurrMark]

I was questioning the dry air the whole time...but it's pretty evident now. It looks like Cookie Monster took a big bite out of the top half of the cookie.
