ATL: BARRY - Post-Tropical - Discussion

[tarheelprogrammer]

Yet another vort was just expelled near 28.5N 90W.

I do not believe that is a vort, it appears to just be an illusion. However, anything is possible when it comes to vorts with this storm. I believe a new center is taking hold a little bit south of the current NHC position. We shall see.

The exposed LLC diving SW is finally being obscured by the higher cloud tops, first time I've seen this all day. Should give it a good boost to strengthen some more through the evening.

There is cirrus fanning out in all direction from the blob that vortex is headed under. I think this is going to be the main one going forward. There is no shear and the center has really tightened up the last few hours.

If true, this thing could be bombing out before it hits the coast. I hope not. Barry needs to continue to struggle.

That swirly going around northern part of circulation of #Barry is not the center of the tropical storm and is heading southwestward to the west side. Landfall of the actual center should occur sometime early Saturday, but life-threatening inland floods continue long after that.

I would point out that the lone vortex is precisely what the NHC identified as the center on their latest advisory. I think it IS becoming the center. As it makes its small cyclonic loop the convection will begin to wrap around it tonight.

The red crosshairs mark the NHC's position:

Wouldn't this be overall better for New Orleans and Terrebonne Parish as far as rainfall? As it moves NW, that track would pull them out of the heaviest amounts.

The wind over the eastern semicircle will lift moisture and intensify the feeder bands that will effect NoLa starting late Saturday and continuing Sunday. NoLa has lucked out thus far with dryer shear from the north but I think Barry is going to moisten up the air south of NoLa as he starts gaining latitude.

Don't expect rapid intensification with Barry.

I've noticed that the rainfall projections have started sliding over to the West, Crowley now is expected to get about 10 inches while Lafayette (20 miles East) now shows close to 18 inches.

Recon pressure is already at 994 mb a good bit away from the center, is this correct?

[Hammy]

What a difference a day makes, all that convection and we're in Dmin? Could be a hurricane already given the winds outside of the convection going on, reminding me of Cristobal in 2014 which also strengthened despite so much shear and dry air.

They are flying a little higher so those pressure readings may be lower than at the surface.

The pressure is extrapolated. Doesnt matter their altitude.

convection on radar is starting to ramp up the east side closer to the center now.. could be about to try to take off..

[SouthFloridawx]

Water Vapor looking much better than yesterday.

[Aric Dunn]

Recon missed the center to the west.. pressure was 991.. so could be 989 in center.

[Airboy]

Looks like recon missed the center a bit in this pass

[ScottNAtlanta]

991.3 is the lowest pressure thus far and they didnt hit the center.

As expected Barry is gradually looking more like a classic cyclone. By tomorrow morning should be even more symmetric. NOLA is on the east side so don’t let your guard down. Rain bands already look to be heading that way. Flood threat is real here for LA.
