Lee's symmetry is certainly better than a few hours ago, but as long as it remains so lopsided it won't intensify much

Visible looks better, IR tells a different story it looks more or less like it has the last several hours. CDO is still getting squished on West side from shear.

Maybe not on Tidbits but it's updated as of 16:37Z on tropicalatlantic.com which seems to often be more reliable

I Dont get how this shear surprised people… Yesterday the 20kt shear zone was present NW of the system.

They were hoping that the upper-level Anticyclone would follow Lee

939mb extrap so pressure is likely around the same but we'll see what the drop has.

Once again SFMR is much higher than FL but with a really high rain rate. I'm wondering if those super high rain rates are causing unreliable SFMR readings

I am somewhat confused on why Lee is moving NW and the steering patterns favor west motion

Likely flagged because of the rain rate of ~75 mm/hr

With how small the eye has become, I wonder if we'll see a period of very rapid intensification once shear abates before the (likely inevitable) EWRC.

He’s moving WNW/295° which that steering current map appears to show for his current location. Then he bends more west over the weekend before slowing and hopefully turning around the periphery of the ridge.

Well, the odds of an EWRC have gone down based on the microwave passes

This could be epic if a big hot tower fires close to sun down.
