ATL: MICHAEL - Models

18Z HWRF is into Ft Walton beach as a 942 MB storm

Based on the track now, does anyone think there is going to be any last minute surprises? Stalling, more of a right hook, head more west? I know it all depends on that front coming down. Just wanting more opinions.

Very difficult to predict those types of things.

It wouldn't be much of a surprise then, would it?

The Gulfstream IV data should be in the 0z runs tonight, that hopefully will help.

I doubt much. Inside of 72 hours now. Think error rate still 100 miles or even less. So, Pensacola to maybe Tallahassee. I'd be shocked of anything outside of that.

Not likely. Models have tightened up today, GFS and Euro are in more agreement and almost haven't budged on a Destin/PCB landfall. It could be 50 miles east or west of that depending on a early/late turn to the NE, but that's the biggest "surprise" I can see in the track if it were to occur.

gonna be bad because of the approach to the coast.

My guess forward speed will be biggest determining factor on E or W of current track... Little faster than predicted might go a bit W and a little slower might go a bit East...

Speed moved to 12 mph now. I think it's set in stone now. Unless someone knows of a slowdown that is supposed to occur.

I think a slightly surprising hiccup is always conceivable. Such as, unanticipated weakening or strengthening, an unexpected slow down, or simply course adjustments where the LLC need "jump" to the N.E. to keep up with an MLC. What I don't expect is for tonight's models to suddenly flash any new surprise wrinkles. I just don't seem to recall any recent circumstances where the Gulfstream gathered wider sweeps of data used for model assimilation, (along with added weather balloons, etc) where subsequent model runs suddenly suggested potentially new or surprising outcomes.
By and large I believe NHC is increasingly confident with track forecast. I doubt the primary 6 hourly Discussion Updates from hear on out will result in more then very minor track adjustments. Any new wrinkle will therefore be a "deer in the headlight" circumstance where unexpected forward speed or change of intensity suddenly poses a quick forecast tweak. So for now we watch, and wait.

If it goes as forecasted then current track should verify, but as recent as Flo where it was supposed to be slam dunk track, we know how that turned out.

There are always possible eyewall replacement cycles just before landfall.
This time of year if there is any shear at all it can bring dry air in and drop a systems intensity a couple categories in just a few hours.
Rare but possible.

Yep...systems tend to weaken on approach to this area, prepare for a 3 or 4 and hope it weakens,4 will take off roofs easily

It's moving a bit faster than forecast, LF spot could be about 20-30 further west than forecast.

Based on its current speed plus the likelihood that it will speed up more, it'll likely make landfall between 5-7am Wednesday.

00z 3km NAM is 7mb stronger and a bit further east than the 18z through hour 19. It is the NAM though, so take it as you will...

That might already be happening, on the latest sat IR loop it looks like convection is shrinking significantly, particularly on the west side, and it looks like a big band of dry air is wrapping into the system from the south.

The shear is supposed to be relaxing soon though.

This belongs more in the discussion thread, but the reduction in size isn't a dry air intrusion. In fact, its likely quite the opposite. Inner core convection is the most intense it has been and wraps further around the center than any time in the past. The shrinking of the envelope is likely a result of Michael consolidating an inner core.

Good evening folks.

Due to the high volume and sensitivity of the situation just a reminder as models start to trickle in for the 0z suite to stay on topic.

GFS down to 949mb at hour 39

943mb hour 45 about to make landfall
