Getting mind-numbing seeing those numbers with this IR satellite presentation

Lee: fuck your erc

This is going to keep strengthening for a bit. Hope they are sending another plane out there soon.

The 11pm discussion described favorable conditions for strengthening through around noon tomorrow, at which time they were expecting peak winds that were just measured by the recon flight that just went through.  
 

So, yeah.  would be nice if we could have more recon in there later this morning to see if Lee does approach Allen territory on the wind speed.

 

on that note, it’s way past my bedtime.  💤

Appears the eye clouded over as well, at least on the visible satellite. Also might have not had enough coffee yet lol

I think the eye is just tightening up more and the intense convection is spilling a little high clouds over the eye

Wonder what was up with the sudden change in structure the last few frames. Went from perfect eye to contracting and losing some of that symmetry around the eye. 

I think we may be seeing the impacts of southwesterly shear mentioned in last night’s discussion.

These microwave shots are gorgeous.  No ERC in the near future.

IT seems pinched off on the west/northwest side and the eye clouded over.  Ruling out ERC, is there shear?

Even ARCHER is messed up - blue being the forecast, red being where ARCHER puts the center.

Ahhh, yes it is.  25kts from the SW.

  • The title was changed to Cat 5 Lee | 165 mph 926 mb | closed its eye, sleepwalking?
