Recon found winds of 127 knots at 937mb in the eyewall and given the pressure surface at sea level of this dropsonde was around 965mb those winds are only 250 meters or so above the surface...pretty damn impressive

127 knots is insane. That is practically a strong 4 wind strength. If those mix down, we could see a big jump. If not, then we should see a 3 soon at least.
