Blah blah blah....on the HMON. The NHC at this point has the track solidified, say within 50 miles either side of a forecast point, for landfall. The only thing remaining and is always the somewhat unpredictable at this juncture, is intensity at landfall. If you are worried about the landfall location, you can know that it will be slightly east or west of the mouth of the Mississippi river. Put the models away at this point. Just my .02 from watching the pros at the NHC for over 30 years.


Normally I would agree with you, but this is something that hasn't happened too often, so we aren't sure of what is happening, and the shift of 50 miles is a big difference


It was just a misplaced model thread post blin. I don’t even like the HMON. I didn’t even agree with the model output and didn’t offer a judgment call. That was just commentary on the output track on a geographical location that is a sitting duck in more consequential situations. But it’s whatever and expected.

Despite the shear the center is still well within the cdo.

The cold cloud tops on IR are showing much better symmetry.
This is the level where the bigger shear was.

This storm keeps defying most of the model intensities and for that I believe it gets steered more Northerly toward the Coast, I'd bet on MS/AL border.

He’s so close to becoming a hurricane...just needs a little more 65 kt SFMR readings...

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Check the water vapor loop. Plenty of shear and dry air to Marco's west. I see NHC's track exactly matches my forecast, with the exception of 75 mph (them) vs. 65 mph (me) at landfall. I just don't see such a small storm in even moderate shear (and dry air entrainment) keeping hurricane strength. It may have already peaked this morning, but could reach hurricane strength in the next 12 hrs before weakening due to increased shear/dry air.


It's not a big hurricane and that also plays a factor but what I was pointing out it's Moving with the best environment for it to function it's not in the WGOM.With that being said really makes me wonder does it go in way further E WV sure would suggest it? :wink:

Accounting for the feeder band, excellent symmetry.
No doubt pushing out shear.

CAPE dramatically increasing in a huge portion of the GoM west of Macro.
Looks like a long track ahead thru a solid Theta-E ridge.
Diminishing shear and a pinhole cane.
Massive rain rate in a continuous firing hot tower.
IMHO 95% chance this ramps up thru a good portion of the day.

As it relates to Laura, would a more potent Marco create a much larger weakness for her to follow? You're talking about a 48 hour difference between his landfall and hers.

Can someone share a side by side comparison of the shear environment that Michael was in vs what Marco is in currently? Michael managed to fend off shear relentlessly and it would seem Marco coming in on a somewhat very similar trajectory that maybe there is something to that approach angle and the pattern setup that allows these north moving systems to defy the shear laws that typically govern tc’s.

Not implying this will become a major like Michael... it just feels a little familiar
