I think shear is really taking a toll now. I think it's being sheared off that way.

Satellite is from 12:56am EDT. NHC track at 11pm EDT. 1005mb icon was at 12:40am EDT.



Plane exited to the NE:



Look at the winds to the west. There's barely a hint of a west wind on that last pass from the SW quadrant to the NE.

From the NHC 10pm CDT discussion:

"Marco is feeling the effect of strong southwesterly shear. The
center, as identified by an Air Force Reserve Hurricane Hunter
aircraft, is displaced to the southwest edge of the convective
canopy. That said, Marco has not quite fully decoupled yet and has
moved well right of the previous forecast. Data from the plane
indicates that Marco has weakened; the highest flight-level winds
were only 58 kt with unflagged SFMR winds just above 50 kt.
Marco's intensity has been lowered slightly to 60 kt, but this is
probably generous."

It's more decoupled now it seems. Which is good news.
