Re: ATL : INVEST 93L - Discussion
I just looked at water vapor levels and they seem to suggest improving conditions with respect to the dry air north of 93 and west of 92. So long as there is spin there is still opportunity, do not understand why I do not see a corresponding decrease in SAL, but if there is more humid air and warner temps in her way, I want to watch it.

well said Portastorm......interesting that 18Z GFS has backed off similar to the 12Z EURO......
but look at this sucker at 384HR...![]()
that is IKE / IVAN like in size. Huge circulation!!! sorry OT I couldnt resist...

The 12 day GFS model backs off and the 16 day model shows a large storm. This gets interesting.

Disclaimer: 50% of the time I have no clue of what I am talking about. Chances are I am taking a less than educated guess that sounds good because 10 years ago I stole Mike Watkins book 'The Hurricane and its Impact'.

[quote="WeatherLovingDoc"]"underthwx ... it is the GFS which is the main American medium-range computer model. This model and the European are considered the two major medium-range computer models. "
All reasonable posts are welcomed here, underthwx. You did well in your question, as it taught me, and maybe others, what the main weather community medium-range computer models are. I didn't know what Portastorm mentioned, and your questioned helped enlighten me.
Many of us keep low profiles, and stumble repetitively over weather words. For example, no matter how many times I try to grasp the difference between "trough" and "ridge" I stumble. One day I think I get it, then realize I don't. I'm a visual thinker and will be happy when the day comes when I finally truly understand their difference.
Keep on posting, and welcome!

Yea, it's almost went poof completely.....Whether it will come back or not, who knows, but it's also very possible that we may not hear from 93L again.....

Who said 93L was dead?
Look at the anticyclone that is in the area.

Also, vorticity has increased with 93L:

Don't call it a comeback because it was never gone!

Currently has the most convection I've seen all day.

IMO, we are seeing the beginning of 93L's comeback!

Yeah, their position is well E of the deep convection and the increasing vorticity (see map above). Wonder if the convection continues they will reanalyze this waves position??

pretty likely.

Re: ATL : INVEST 93L - Discussion
the key was 50W and its almost there so I would have expect it to fire off some convection. Now if it can mantain is a different story. It is entering a better environment and with an anticyclone over it already thats a huge plus....
