Re: ATL: TEDDY - Hurricane - Discussion
Teddy is looking extremely impressive right now.
What a monster.
Are there anymore flights scheduled anytime soon?

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC, NWS, or SPC for official information.

Tomorrow morning!
Looks like the last flight.

Re: ATL: TEDDY - Hurricane - Discussion
Honestly surprised they're still doing recon flights on a storm in this position that is starting to transition. Teddy is clearly still a powerhouse though. 105kt FL and 65kt SFMR seems fairly good to me though for a storm that is transitioning. He's been one of the most interesting storms to watch this year.

Teddy’s cloud field is so big, I might be able to see the outer bands here in far western Connecticut.
TS-force winds extend out to a maximum of 345 miles according to the NHC, so the wind diameter of Teddy is nearly 700 miles across!

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Recon is finding extrapolated pressures in the mid 940s!

Re: ATL: TEDDY - Hurricane - Discussion
Starting to look extratropical to me, with not much in the way of deep convection near the center.

Very Sandy-like, enormous post-tropical cyclone with the pressure of a solid Category 3 hurricane. Fortunately for the U.S., occurring several hundred miles to the east.

Fairly steep pressure gradient too despite the extratropical appearance.

Re: ATL: TEDDY - Hurricane - Discussion
Surface maps of the Ocean Prediction Center find a warm front and a cold front. The warm front seems connected to the center or at least close to it, while the cold front seems merely embedded in the circulation. Possibly it has to do with the formation of a warm seclusion. Cyclone phase analysis shows Teddy as being an asymmetric deeply warm-cored cyclone. Windy and other wind maps find a low wind speed near the center, despite Teddy's increasingly extratropical nature.

Well, that is not exactly how that works. The TS winds may extend out 345 miles from the center but that doesn't mean it does so in a perfect circle. That 345 miles may only be in the NE quadrant, while winds on the SW quadrant may only extend out 50 miles. Just as an example. Some storms are more uniform than others, though. I haven't paid close attention to Teddy to know if his wind field is consistent in all quadrants.

It’s pretty close to symmetrical as of 11am. It’s still uneven (360 nmi NE and 270 nmi SW) and has a diameter of 630 nmi, or 725 miles.

Here are the TS wind radii. So about 630 miles.
34 KT.......360NE 330SE 270SW 300NW.

Looks like a textbook Shapiro-Keyser extratropical cyclone after cold-frontal fracture.
Current satellite imagery of Teddy:

And compare that to this EUMeTrain graphic:

Those are in nautical miles. The NHC says the maximum wind radius is 415 miles. Converted to nmi, it’s 360.

Yeah, I know. Should've been more clear I guess. Also lol we posted pretty much the same thing at the same time
