Yes, ther are two missions in Ike and they penetrated the eye nearly at the same time. And the one mission from West to SE flew some a circle in the eye and found 953 hpa. It also found 127 kt flight level wind in the SE eyewall and this is believable, because you can see they extremely violent processes in the SE-E part of the eye in the visible loop on Tropical RAMSDIS. The other flight from NE to SW missed this feature. So very interesting dynamics in the storm right now!
edit: Sorry, confused the directions and missions totally.  Mission 4 flew SE-NW through the eye and found the high values in the NW, obviously in the open part of the eye. Is there an explanation for this?

Ike was officially re-upgraded to Cat 3 at the 2pm intermediate advisory, with winds of 115mph. This seems conservative based upon the current recon information (which estimates winds at 119.7mph). Pressure reported at 956 by the latest vortex and this is in the advisory.
Interestingly, the advisory says "Some fluctuations in strength are possible
during the next 48 hours...but Ike is expected to remain a major
hurricane strength during this period." Since Ike is now on the edge of major hurricane strength, this may indicate some strengthening?

One one hand I am relieved that my own town is now out of Ike's cone, but I am horrified that it seems that New Orleans is again right in the middle of the projected path of the hurricane. Can New Orleans take yet another near miss or hit?
I'm afraid not. Gustav leveled most of the high tension power transmission lines south of I-10.
Many will be without power for another week or two as it is.
Distribution and transmission lines are down in much of SE and S Central Louisiana. Another storm shouldn't do much more damage other than delay repair.
It will cost the evacuees more money to evacuate and the area will lose tourism money and tax money.
The problem, as I see it, is that I believe many New Orleanians are unaware that we are getting closer to being inside of the cone for Ike. Even places that have power may not have cable or internet. Plus, as of this morning, both wwltv.com and nola.com were focused on Gustav restoration. Fox was broadcasting stuff about Ike, and it was on the second page of the Times Picayune, but it's not headline news around here. Couple that with the miss, the problems with re-entry (from the evacuees perspective), and the lack of money after Gustav's evacuation, and this really concerns me.

I hope you are right. Living here in Pensacola.
My fiance' is outside puting the last screws in the front windows for our panels of our house just in case. With both of us working in the medical field, me in an ER and him for a home health care company, it makes times like this tense. He could possibly go in call mode by the middle of next week. There have been many times in the past ( Erin, Opal, , ) that we have both worked closely with the Medical Shelters that our county sets up. Their company usually provides all of the equipment. It leaves me here usually making most of the home preps by myself. By him doing this today hopefully I will not have to get the prescription for Xanax filled.

So, this is the third time that they found such high values for peak winds in differnt parts of the eyewall. This time it´s 123 kt in th flight level ad 121 kt at the surface. That´s really no transient feature anymore, if such high values exist over hours! Pressure is arounf 951 hPa!
And I also don´t agree about the structure of the storm. It´s quite good outflow in all quadrants. I would expect further intensification of the storm.

Cloud tops are definately cooled considerably over the last few hours, although the eye has not yet reappeared. My guess is that the will be very reluctant to upgrade to Cat 4 with the current satellite presentation, but recon reports sure make a convincing case right now.

Yes, will be interesting to see, what the says about it. I think, they will stay with the central pressure and set it to 110 kt or so.
By the wy, CIMSS maps confirm that shear has relaxed considerably.

Water vapor imagery, which still showed a fair amount of shear this morning, shows it to be relaxed now as well. We could be entering another phase of rapid intensification, unfortunately. The only thing it's missing is a clearly defined eye.

There seems to be sufficient evidence now to bump the winds iup to 110-115 kts, even considering the less-than-ideal satellite presentation and inner core organization. If it does finally close off its eye at some point and become more symmetric in the next 24 hours, that will be bad news.
Latest recon has the pressure down to 950mb.

last pass by AF Recon shows a 6mb drop in about an 2 hours... from 956 to 950mb... still open on the west side of the eyewall... G-IV is up from islands... so we should get some good data in tonights runs.

It looks pretty symmetric right now, to me, just looks less than ideal in terms of not having a nice eye showing up (yet, I'll go ahead of say, given that pressure!). If the trend continues, it will definately be bad news for the Bahamas and the Keys... and points beyond.
Do we know for sure that the G-IV is in the air now?

The other mission penetrated the center shortly after the other. 950 hPa are confirmed and flight level winds with 128 kt too. In the HDOB there had been 118 and 115 kt surface winds. The peaks are in the NE and N- part of the eyewall.
Yes, there is a G-IV in the air. Saw a dropsonde report recently.

That´s the last confirmation for a potent cat. 4 and a significant intensification during the last hours: A dropsonde in the NE- wall reported 124 kt at the surface!

well we have missions 03 - 06 going on right now for ike. An AF Recon is now almost due east of Daytona Beach at 30kft droping dropsondes... while the G-IV in north of Ike now droping dropsondes and an AR Recon is flying in Ike right now at 10kft... while the NOAA plane is heading to the base in the islands.. we should have good data for tonights models...

agree... the dropsonde hit 182mph at 827mb (roughly around 4kft above the surface) and showed an avg. of 150mph winds from 3-5kft. **cool to see the GPS Dropsonde traveled about 9.2miles from its launch location til it hit the water** in about 4 mins from launch from 10kft to it hit water 9 miles away

That or too much data for the models to ingest.
Here's hoping that the extra data will refine the Cone. To some degree.

having been in the NOLA EOC and working on the city evacuation (but now back home in Florida), the possibility of another storm is of great concern. Many residents now feel like the left for "no good reason"...after all..."nothing happened". Getting people to do this again...in a short amount of time will be tough. And a strong storm will prove a disaster.
For now...it is early and we need to see how much interaction does with Cuba before we can make some solid guess-timates on track. I just hope and pray that people will stay smart but knowing human nature I remain fearful.

The models have been trending more to the west, however everyone within the cone should keep a close eye on this as things will become more clear over the next couple of days. I hope the "residents" of Key West take the evacuation seriously and head north. The conch republic contains a sturdy bunch but this is no time for a hurricane party on Duval Street.
