ATL: ARTHUR - Post-Tropical - Discussion

[Syx6sic]

Just for some perspective, Hurricane Issaac 2012 had a minimum pressure of 976mb and still was classified as a tropical storm at that point.

Some recent storms with similar pressures to Arthur but peaked as tropical storms -

Tropical Storm Fay (2009): 70 mph, 986 mbar
Tropical Storm Helene (2000): 70 mph, 986 mbar
Tropical Storm Grace (2009): 65 mph, 986 mbar
Subtropical Storm Nicole (2004): 50 mph, 986 mbar
Tropical Storm Gabrielle (1995): 70 mph, 988 mbar
Tropical Storm Arlene (2005): 70 mph, 989 mbar
Tropical Storm Barry (2001): 70 mph, 990 mbar
Tropical Storm Nicholas (2003): 70 mph, 990 mbar
Tropical Storm Peter (2003): 70 mph, 990 mbar
Tropical Storm Frances (1998): 65 mph, 990 mbar
Tropical Storm Arthur (1996): 50 mph, 990 mbar

Funny to see Arthur on this list from 96 shows he likes to be known

A list here has been redacted to save space

Actually I think that list has a few errors, Arthur '96 had 1004 mbar pressures as a TS, and Fay is 2008 not 2009.

Best Track still keeps it a tropical storm. Maybe we might not see any upgrade at 11 PM.

01L ARTHUR 140703 0000 30.2N 79.2W ATL 60 990

Wow!! Did you just pull a "Rain-man" or did you look that up?

Well I remember Arthur '96 being rather disorganized (it had an exposed center) and I knew Fay for sure was in 2008. The list was a copy-paste though of a list someone else posted on Storm2k.

Funny cause The Weather Channel keeps mentioning the POSSIBILITY of a Special Advisory for a upgrade to Hurricane. Though it's probably just them talking.

[Alyono]

should be a 988 pressure though with the NOAA recon

I'm a bit skeptical of this sort of thing from a media outlet, most of what they put out anymore is just "stay tuned and keep giving us ratings" ploys.

I miss the old weather channel, it was almost all weather forecast and not some stupid mining show.

Water vapor loop of Arthur's existence. Courtesy LSU.

[gatorcane]

Saved WV loop showing the front passing through Ohio/Kentucky/Tennessee making good progress eastward. 500MB winds are in the process of veering to a SW-to-NE flow across the SE United States. Arthur should be making the much anticipated turn soon.

[Hammy]

Dry air appears to be expanding again, is this a diurnal cycle?

That's the difference between the NHC and TWC - government forecasters are not told by a control room producer what to say for the sake of a rating point...

Looks like Arthur is struggling again with dry air AGAIN!

I have DirecTV, a few months ago they took out TWC and put in Weather Nation, pretty nice, all weather 24 hrs, but after a while I actually started missing TWC for some reason, lol. But now they put back TWC and they kept Weather Nation on the line up, so now I feel I have the best of both worlds, the one night a week I may turn both on, lol.

[ScottNAtlanta]

The lowest pressure measured by aircraft was 982.8mb yet the vortex says 988...that seems like an awfully large discrepancy doesn't it. It also looks like the dropsonde missed slightly.

I have a feeling that this will hit nc as a cat 1

I preferred the 2003-2005 Era of TWC, a.k.a. the ("Live By It" Era). Of course it seems with TV all good things must change eventually.

I believe the 982.8 was an extrapolation and 988mb is what was actually measured.
