I will have to disagree. Its going to be crawling into a  very  very  cool stable airmass. The weakening  is going to be dramatic. If  it does  landfall in the  pnahandle this seems reasonable. Most  likely a high end tropical storm but as we know when a storm is falling apart it  has a  very  hard time transporting wind to the  surface. Very  likely devoid  of  convection with a winterlike rain shield to its  north. Whatever sustained wind the  NHC claims  it  has at  landfall will not  come  close to be seen on land.

Looking at just how far west some these runs are, sure....it just depends on how close it gets to the west coast of FL. I shouldn't have initially been so dismissive before viewing all of the AM suite.

What does storm surge potential look like in Charlotte Harbor and surrounding canals of Punta Gorda?

Per radar, Ian is still trying to close off the eyewall. Judging by the past few hours this will likely take at least a few more hours to occur. Until it does so, Ian may maintain only modest strengthening. At the very least, land interaction may end up tightening the core starting in 12 hours or so.

Just making the same obs and drawing the same conclusions.

NHC will typically follow TVCN quite close, which is a corrected consensus blend. Until this shifts west I wouldn't expect much in the way of changes with the cone. It was the best scoring track "model" last year at nearly all lead times.

Exactly.  Until that starts to correct TPC track adjustments will be minor.  Also, Tampa still fully in the "cone" any tug to the right, by even 15-20 miles will put Tampa under the gun for the worst of the surge.  Not over by a long shot for serious surge flooding into Tampa Bay.  For Tampa to experience the worst possible surge the center would need to cross the coast just north of the metro area.  Angle of approach also important and we're not likely to see the worst case scenario as far as that goes.  Ian will be moving NNE approaching Tampa as opposed to worst case NE or ENE.  Makes a big difference.  Also Ian moving slowly so any wind trajectory the keeps winds coming up into the bay will be for rather long duration.  Delicate situation and not fully resolved yet IMO.

It's pretty astounding how a hurricane in the Western Caribbean in September could have issues with dry air entrainment but you can clearly see all of the dry, sinking air on water vapor loop.

I still think that once Ian gets North of Cuba we're going to see a period of steady intensification, with a likely max intensity near 115-120kts. 

Every major model shreds this storm once it gets North of Tampa so assuming that the center passes at least 50 miles offshore at Tampa's latitude, biggest story might be inland flooding in the Southern Appalachians. 

I know a lot of people that canceled Disney plans for this coming week and I kept telling them that the average track error at day 5 is more than 150 miles. If the HWRF/GFS camp end up being more correct, Central FL might not see much impacts at all.

Dr. Greg Postel from TWC was talking about this. Was showing the radar and you could see a big void of precip wrapping into the core. He said this likely is inhibiting rapid intensification for now and only allowing gradual intensification. Dry air was never really supposed to be an issue till it got more north into the Gulf.

Tampa is about the latitude where conditions are going to become rapidly unfavorable to maintain a strong hurricane.  Intensity will fall off quickly north of Tampa Latitude - especially with very slow movement.  Satellite presentation is going to degrade quickly once past about 28N.

If there were ever a season to pull that off.... :lol:
