This morning's GFS vs evening. Both images are for Saturday Midday. Shift west.

I think that west shift is a tad overdone based on current motion. Definite shift west, but mot that much.

Ophelia is actually building an inner core, wasn’t expecting that. Further evidence it has transitioned to tropical

Joking aside, I wouldn't be surprised if the 11 PM or 2 AM EDT update upgraded this to a hurricane. There's an argument that it already is one, but the next recon flight should resolve those arguments one way or the other.

it would weaken faster the farther inland (west) it goes, as over the outer banks is still basically over the ocean

The pressure is already lower than the init value. I wouldn't put too much stock in that run.

Can confirm. We usually ride out tropical storms here cause we get a couple every year, but bars are starting to close now, and police are closing the streets.

Should've been upgraded at 5, but I understand why they didn't...

Yeah it’s definitely close one way or the other. Inner core development looked good for a while but looks a little wonky now. Wide swath of 70-75 mph winds about 1000-1500ft up on radar. Would prefer to see readings closer to 80 to feel more certain.

Plane is on route to Ophelia and we will know how is the structure of the storm, how are the highest wind speeds and how low is the pressure.

Radar velocities have come down 10-15 mph from the ~85 mph couple hours ago, I suspect peak may have been missed.

They left this a tropical storm but if I were near the coast where this was going to make landfall I'd make preps for surge and power outage. Winds near landfall are going to be stronger than those 980 mb cold core northeasters they get in the winter.

Cloud tops are much warmer than earlier, I think it's peaked and is on the decline now, though maybe recon data will surprise me

Definitely cool to see but a big oversell on “absolutely insane.” Looks like some tropical storm level winds. Why do so many people use extreme terms - insane, ridiculous, jaw dropping, mind blowing, stunning, etc.?
