ATL: ANDREA - Post-Tropical

[bahamaswx]

Firing nicely now.

[NDG]

IMO, we have at least a TD.

Ball of convection blowing up very close to the center.

I haven't seen you post here in years.

I haven't followed Invest 91L (or 90L, what happened to that?) much but it appears to be a classic June Gulf system, similar to TS Alberto in 2006.

Haha, I became a lurker for awhile, but I decided to become a Meteorology major, so I figured its time to go back into the fray.

The next TWO is going to be interesting. This flare up has been fairly persistent and hasn't been sheared off to the east. Could possibly have Andrea before the day's end if this continues.

Nice size hot tower beginning to fire off.

Looks like this could be a long duration one.

Hard to tell but it looks like a more defined surface COC or LLC is trying to redevelop closer to the deep convection, near 25N and 87-88W area.
Vis satellite should give us a better picture.

[GCANE]

Hot Tower is pretty far from the current fixed COC.

However, it is very likely the COC could get pulled closer to it.

Not just off-the-scale rain rate, but cloud tops also very cold with the hot-tower - text book

Sorry for being off topic here, but I was just scanning RAP and saw a very nasty set up for OK this afternoon.

Off-scale helicity and CAPE over 4000.

[Dean4Storms]

Boom, this has a window to develop further with the latest convection burst and shear letting up. I now wonder if this deepens more than what GFS and ECM have depicted if it doesn't move more poleward toward the Panhandle as the GGEM has been predicting.

[NDG]

This is the most concentrated converge I have seen with this system with H85 vorticity increasing over the eastern convection a sign that the surface low pressure might move closer to the convection this morning.

[caneman]

Looking much better this morning. Lopsided yes but you expect that this time of year. Think the LLC will develop under the convection. Looks like we'll have a TD today in my opinion.

[GCANE]

The off-scale high rain rate only lasted about 1/2 hour, but it continues to fire very cold cloud tops.

[Aric Dunn]

as suspected last night. that vigorious mid lvl citrc had spawned a new wahat appears to be a well defined llc with organized deep convection firing and maintaining. very likely nhc will find a td if not a ts today.

Good morning, G...hopefully it will persist long enough to start warming the column and give a boost to some anticyclonic assist aloft

[NDG]

For the most part this is a typical looking tropical system for early June in the GOM, nothing more expected.

[Aric Dunn]

the bouy very the llc has had decent pressure fall and sustainded td winds . probably very like thete are sustained ts winds in the deep convevtion

And this buoy is no where close to the deep convection which is a good 100-150 miles to the south from this buoy.

CAPE over 4000 is always worth posting about regardless of the topic, good work

you need a closed circulation at the surface, not just wind
