Milton is also growing in size, it seems as it is entering the Yucatán channel and getting away from the frictional effects of the coast. He has room to stretch his arms

NHC cone for Helene 24 hours prior to landfall did not even include the county where landfall ultimately occurred. The guidance models were in FAR better agreement then than they are now - and had been for a couple days - and were all wrong.
Milton has been even less predictable. Lest anyone get too comfortable of what they think they know..
this is factually not correct... the landfall point was a bit on the right side of the 24 hour cone, but it was within it... refer to https://www.nhc.noaa.gov/archive/2024/HELENE_graphics.php?product=5day_cone_no_line_and_wind
But... I will edit this post to emphasize that your basic point is correct, overly focusing on the track centerline is not wise as is living and dying with each model cycle and/or wobble (although wobble watching does become relevant shortly before landfall).

Re: ATL: MILTON - Hurricane - Discussion: 165 mph / 902 mbs
Going to throw this model out there for 3 reasons: (1) it was the best model through 72 hours for Helene, (2) it was the only model that showed the southern track towards the Yucatan for Milton early on, and (3) it's performing the best for Milton right now as well:


This models solution for landfall may not verify, but the take home being, don't let your guard down or become hyper focused on the center of the cone right now. This may come in more north, or more south, all we know is intense hurricanes like Milton will jog/wobble quite frequently (as the NHC also stated in their latest discussion).

Re: ATL: MILTON - Hurricane - Discussion: 165 mph / 902 mbs
A consistent thing I've noticed with rapidly/explosively intensifying hurricanes recently is SFMR readings are almost always higher than FL wind reduction estimates. This data characteristic has been seen in a lot of recent examples of RI hurricanes; Beryl and Lee come to mind as very recent examples. There are two likely explanations for this: the SFMR wind estimation algorithm is inaccurate at extremely high wind speeds, or winds mix down to the surface more efficiently in rapidly/explosively intensifying hurricanes and the standard FL wind reduction factor is misrepresentative. Either way, I expect that this will be an active area of research in the coming years.
It was similar research into how FL winds correlate to surface winds in 2004 that justified hurricane Andrew's post hoc Cat 5 upgrade a decade after it occurred. Perhaps analysis in the future might examine if standard FL wind reduction factors are universally applicable in RI/EI cases. Conversely, there may be research that corrects the algorithm that defines the relation between SFMR brightness temperature and surface windspeed for the high-end situations. Regardless, this may be an active area of research similar to the research advancements that were occurring in the early 2000s.
If any meteorologists have any insight into this that I am ignorant of, it would be greatly appreciated. This is just my inexpert opinion.

Re: ATL: MILTON - Hurricane - Discussion: 165 mph / 902 mbs
I grabbed this WV loop for people to see the players on the field (so to speak). You have the shortwave diving south in the western GOM. That is what is steering Milton to the NE. Also notice that Milton has good outflow N and S. That shows an anticyclone right on top of it. Intense hurricanes can often create their own anticyclone. I don't see the jet that will cause the shear later on yet. This is what a textbook healthy hurricane looks like

SFMR data on NOAA hurricane hunters have been deemed unreliable and therefore not transmitted. Not sure if the same can be applied to AF hurricane hunters.
In any event, NHC has been increasingly sceptical of SFMR performance in higher wind speeds in recent years.

On IR, it looks like it’s getting a bit ragged and winding down.

It's an issue with the sensors, not a dismissal of the science of SFMR. AF continues to transmit from their planes and NHC continues to consider the results.

I just snapped that WV loop about 10 mins ago...looks fairly healthy to me currently

Fascinating. And how is it doing with intensity or is strictly a predictive model for the track?

I'm aware of NOAA's decision to not use SFMR data operationally, from the language they use this seems to be due to degradation of the actual equipment onboard the WP-3s rather than systematic methodological failure of SFMR itself. This would be corroborated by the Air Force still using SFMR data. As to your second point, I would agree that the NHC's reluctance to trust SFMR data would point to the SFMR wind speed algorithm being unreliable in the extreme high end scenarios rather than FL wind speed reductions being inaccurate.
I would love to see an analysis of NOAA tail doppler radar profile data to examine vertical wind profiles and how efficiently winds mix down at different rates of intensification.

Re: ATL: MILTON - Hurricane - Discussion: 165 mph / 902 mbs
As plenty of people have mentioned weakening is relative. Yeah it’s better to get a 940’s system than a 920’s or lower. But don’t think that won’t be a historic storm for those who have to deal with it. Hurricane Betsy 1965 came in Grand Isle at 946. It was the benchmark storm in New Orleans for my parents generation (I was too young to remember) and was the big storm until Katrina hit. Milton could conceivably still hit in the 930’s which is worse. Gonna be tens of billions in damage across the state, and lives will be lost. Regardless of whether it goes in Tampa Bay or south, millions will still be affected. Sarasota-Bradenton has over 800k people and close to 900k if you consider down toward Venice. Orlando has over 2.5MM population and there is another 600k in Titusville/Melbourne/Mims/Cocoa Beach. Plus there’s a lot of people in between those statistical areas. This isn’t a big bend type storm or Panhandle hit because of the number of people that will be affected. It’s gonna be ugly maybe in ways we haven’t seen yet despite all the storms we’ve tracked together over the years.

I’d need to locate the exact source for this, but as far as I recall NOAA did an update to the SFMR algorithm in 2023 - the wind speed at the high end of the spectrum is still running a bit hot, but it’s lower than right after the 2015 update.
NHC and NOAA do seem to have different takes on this issue. NHC is more sceptical to SFMR winds than NOAA.
