Not sure what you're seeing IMO.

how far right?
1. what are the chances of 95L detatching from a front?
2. how do you tell if it is attatched to a front based on satellite (with no overlays)?
3. what difference does it make if it is a 35mph low attatched to a front or a 35mph tropical depression just detatched from a front?
Texas or Louisiana?
StormW. and more to come .
My discussion mostly dominates 4 area's of interest, and they will be listed from least threat to greatest threat on this blog.
95L likely to not amount to nothing much
A non-tropical low is situated about 100 miles south of Louisiana. The system is very small and very weak, with cloud tops only in the -50C range which is very warm. I expect that 95L will not amount to much more than some rain for Louisiana. 95L should continue a WNW-NW direction in the next day or so before finally making landfall. No models develop 95L, increasing the unlikelihood that it amounts to much. The NHC current gives 95L a LOW 10% chance of development in the next 48 hours.
(Most recent satellite image of 95L)
Bahamas disturbance a small threat to develop
My second discussion is on a area of convection to the east of Florida situated not to far off the Bahamas. Some of the models have been developing a trough split off Florida and developing it into at least a sub-tropical depression off the coast of the Mid-Atlantic states. The system currently is very disorganized, with no organization to speak of what so ever but does has a chance as it gradually moves N-NE the next couple of days. I give this disturbance a 20% chance of development in the next couple of days.
Lesser Antilles disturbance a threat
A Highly amplified wave is approaching the eastern Caribbean. This wave current features a sharp V-shaped axis to it, a common structure of a very powerful wave and it can be seen also on ASCAT that it is very formidable. No models develop the Lesser Antilles disturbances at this time, however water temperatures are very warm ahead of this system and I suspect that this system once it goes farther NW (this system might actually enter the Bahamas, so we'll watch it or it might go into the Western Caribbean) that this could become either Bonnie or Colin. Its defiantly a wave we need to watch even though there is very little if no model support to support the system. I current give the Lesser Antilles disturbance a 30% chance of development.
96L: The one to watch
A strong wave in the Western Caribbean is a large threat to develop over the next couple of days called Invest 96L. 96L is a very large wave and reminds me currently a lot of the invest that became Hurricane Alex, 93L. The wave currently has strong model support from the ECMWF, which is very reliable and was dead on will all of 2009's systems and with even more so with Alex in terms of genesis and track was spot on through its entire lifetime. The most recent run of the ECMWF and the CMC show the possibility that 96L will go more north than Alex did, and might even thread the Yucatan Channel which would be very bad. The ridge however would force 96L back west towards Texas. It is however very earlier to speculate on track as the situation unfolds over the next couple of days. The wave currently is organizing quicker than 93L did as surface pressures are already falling and vort is stronger at the 850 mb level than through most of 93L's time. I currently give 96L a 50-60% chance of developing into a tropical cyclone the next couple days. The NHC gives it a MEDIUM 30% chance of development over the next 48 hours.
The tropics are waking up gang!

How far right?
One of the reasons it's not warm core/tropical.
Think ima have to go with BAMM or BAMS. I have no clue what BAMD is doing!
Out for now, be back later....

You could of posted that on your blog but thats ok.
Lol BAMD is meant for strong deep systems, i.e. major hurricanes, BAMM (Beta Advection Medium) is probably a more viable track for this system.
Oh, ok, I wasn't familiar with what those model abbreviations stood for. So I guess that means BAMD is Beta Advection Deep and BAMS is Beta Advection Shallow/Beta Advection Small?
"The wind shear around the low is expected to weaken into Monday, potentially giving the low a small window of opportunity for development. However, if the low drifts too far to the west, it will miss this opportunity.
Whether or not this feature develops into a tropical system, it will continue supporting widespread shower and thunderstorm development from Louisiana to Florida West Coast waters throughout the holiday weekend.
Any of these thunderstorms could produce heavy rain over a short period of time, resulting in slow travel, street flooding and disruptions to outdoor festivities.
Where the thunderstorms organize into squalls, they can bring more substantial to disruptions to land and sea based cleanup and containment operations."
No, it doesn't. The Horizon site is East of any of those tracks.
CLP5 is a climatological average model based on time of year and past history for that area. But yeah in terms of impact to the spill zone I think this yields more potential for concern than Alex.
The oil-volcano is at least 200 miles NNE of where those runs are.
Judging from the RGB 95L is detached from the frontal boundary. I didn't think much would come of it but I may be wrong..
I hope BP is ready....
You mean east?
Next 97L??
