Right and I agree, just haven't seen enough conclusive data from recon to say for sure its dry air. Its definitely shear as its moving into 25-30kts of shear

Again, concerning topography and the mountains i agree and its common sense. That's not what I was disputing with your claim, the dry air is what I dispute. Need to see more conclusive data from the Recon Hunters before going off that assumption

yes its having issues, but i credit this more to the topography and the mountains of Cuba vs dry air

Concerning the dry air though, topography yes, i agree

Not supported by recon though

Until Ian crosses Cuba we are unfortunately going to see this back and forth game concerning the track in relation to the building HP

Yes they were, NAM pack were among the first models outside of the NOAA NHC in-house models to accurately predict Michaels rapid intensification

Ian moving over some notable warm eddies in the next several hours so I wouldn't be surprised to see another rapid pressure fall

Its coming along nicely, that eye looks healthy

Yes CAMS are Convective Allowing Models. And yes as standalone model runs, no they shouldn't be used. As in......molding a forecast to the track depicted on the NAM. However the closer you get to an actual landfall they help to sniff out the mesoscale environment ahead of the storm (since they are programmed/designed for the mesoscale). In years past I have actually used the NAM to help indicate effective timeframes when possible internal processes would happen. Also, the NAM has a tendency to sniff out last minute shifts in track as landfall approaches. They are effective tools and have their purposes like every other model. Though they are not ocean coupled they also help with forecasting so I agree to disagree with your statement.

NAM landfalls south of Tampa Bay and the FV3 Hi-Res seems to be following the same track. Interesting to see the CAM start to lean towards a Tampa or points south landfall......very similar to some of the EURO op runs and the ensemble runs we seen the last few days

Ian is trying to evolve into a buzzsaw

Indeed we are seeing structure improvements and the pressure is steady now with minor pressure falls. Remember though, there is a lag between us seeing structure changes and the pressure actually tanking. By 5am we should see another significant pressure drop. It takes a few hours for the pressure to respond. It all does not happen at one time

Very healthy CDO with deep convection wrapping around the center. Ian is off to the races now

That suddenly made me hungry...but I'm at work tonight and cant cook shrimp lol

...and we will just ignore the fact its virtualy stalled doing that so yeah, no upwelling what so ever lol

For humor purposes only.......want to see the potential "world record" RI process inbound? A 103mb drop in 12hrs.......brought to you by.......your neighborhood friendly 00z 3km NAM run

And there its is, finally, the eye of Ian

If we are talking about Indian Pale Ale's....I'm game for that lol.

If this rate of intensification continues that we have seen this evening, and it solely depends on Ian getting a CDO and an eye soon, you could be waking up to find Ian stronger than a Cat 1.

Ian is now over 85-87 degree SST's, moving over bath water. Ian has all the ingredients it needs to RI now.

Looking at the environment ahead of Ian tonight, besides the lack of dry air and windshear the OHC is very high ahead of this system. Also, something to note here, there are a few warm eddies ahead of Ian so its very possible this anticipated RI process could lean towards an "explosive intensification" process once Ian gets an established CDO and eye. Its also now following the tail end of the loop current so we should start to see remarkable/appreciable structure changes soon.

Until Ian gets better organized and we see an eye develop, we wont have any better idea in the long term and neither will the models. Expect additional back and forth in terms of track until then

"The little engine that could"

Exactly, which draws into perspective that Ian is deepening at a much faster rate than what was originally forecasted and shown by the models. This is going to be huge/detrimental to the forecast track so I expect further adjustments on the models tonight.
