Re: ATL: KAREN - Models
I know this isn't the discussion thread, but this seems relevant for the models as well. Here is the latest IR imagine of Karen. The center looks to be slightly further East than predicted with NHC also calling it "CENTER OF KAREN NOW NEAR SOUTHEASTERN PUERTO RICO" while moving North at 8mph. If most of the center goes around Puerto Rico, this could prevent some weakening. I assume this could have a significant impact on later intensity and of course model runs.

18Z ICON hour 3 (5 PM EDT) has it just NE of PR, which is too far north by ~60 miles. Distances like that can make a big difference in the ultimate track on the run.

Hah, figures the 12Z EPS is now fully rendered that I got around to posting the above animation. Anyway a few more things.

ICON has been one of the outliers implying much greater interaction with Jerry/remnants as well. I think Jerry falling apart today will make for an interesting 00z.

18Z GFS: furthest west of last 4 runs where it is stalling. might be related to the initialization.

18z GFS still dissipating Karen and brings the remnants west into Bahamas and South Florida.
It looks like the ridging is a little stronger on the 18z.
It looks like the next couple of days and Karen's strength vs. where she stalls, gets captured by the ridge and starts moving west, will be key to next weeks adventures.

It's a reasonable point nonetheless

Re: ATL: KAREN - Models
Not sure anyone mentioned the 12z CMC?
Even though it still does not retrograde Karen, it shows her strengthening significantly in the short term

Re: ATL: KAREN - Models
The new 0z Icon coming in much further SW than before after the turn takes place. Perhaps it picked up on the center reformation?

Much further S (~350 miles) vs the 12Z and therefore implies an increased CONUS threat despite keeping her weak. Regardless, my current concern is for all of the models: is there a new center much further west? If so, none of the models so far are initializing this. This would mean less trust than normal in the models until the true center is known.
