Ok, going to do a bit of analysis on the latest recon mission. From the vortex data this thing looks like a borderline Category 2/3 with 96kt surface winds. Flight level readings from the HDOB maxed at about 102kt winds, though a 114kt occured in the N quad that didn't show up in the HDOB readings. More interesting is the dropsonde. The eyewall dropsonde shows the wind speed at surface (112kt) stronger than at flight level (90kt), and if the 112kt surface reading hit the strongest spot in the eyewall, that would be pure luck. This would keep it a strong Category 3. The eyewall is reported open, and from the HDOB readings the windfield has expanded. Temperature in the eye is 17C (dropsonde reported just over 18.2C) and in the eyewall it is 9C (dropsonde reported 10.2C). This makes a still strong 8C difference, but nothing close to what we saw last night. With another hot eddy in front of it and still a ways to go for land, I would expect this reogranization phase to be over in a few more hours with a new eyewall developing and then shrinking. But first it has to finish mixing out the dry air it sucked in this morning.
