ATL : INVEST 90L

[HURAKAN]

Latest ... not much time, it was a nice practice run!!

Close look at the center

[KWT]

Looks very bare now, pretty much just a naked LLC right now which shows that the systems chances of developing is, as wxman57 said, pretty much approaching zero now. Still as Hurakan also said it was a nice little test run for the real fun and games and overall the models have done fairly well with calling for the lows development.

Still a nice looking circulation for sure!

Loop

Looks like the system has started to be ejected back ENE as the upper level trough starts to move eastwards as well.

[HURAKAN]

It's funny how one disturbance has what the other needs. If we combine 90L and 90E, we would have a depression or storm by now!!

[xironman]

Sometimes they look like they are totally dead then there is a burst as they eject to the NE like TD1 last year

[HURAKAN]

xironman, believe it or not, I was looking at the same image a few minutes ago but didn't want to post it because I'm always the one making comparisons!!! lol

But yes, I agree. Maybe we see some baroclinic enhancement and convection can fire near the center as it's being driven to the northeast.

Right now 90L is purely extratopical and is making its way back out to sea. For this reason, I am not going to do a forecast for it. After 90L makes it past the island of Bermuda, which will likely occur tomorrow night. Just looking at the latest models, and there has been quite a big swing in forecast track. GFS, NOGAPS, and NAM as well as a few others now have yet another surprise in store. These models bring 90L back to the west for the weekend. I've been doing other things today in life that require attention, so I haven't been able to look at the models any more in depth than this. If anyone has, please send me some insights.

Interesting, thanks 789 for pointing that out!

[KWT]

Ah thats very interesting it has to be said, certainly is just extra tropical right now but if it doesn't quite get taken out to sea by the upper trough then a bend back is quite possible.

That being said I'd expect the upper trough to be just enough to shunt the system out to sea, in which case nothingis going to happen, if it gets back west then you can't rule it out but even then I'd be doubtful of anything happening.

Still that would sure be a twist to this system, can't totally rule it out if it doesn't manage to get far enough to the east. Not a bad system to get back into the swing of things really is it!

[HURAKAN]

Consensus ... that's a shift

We've got a fighter here(maybe)

90L isn't long for this world. The upper low/trough over the top of it is forecast to shear out over the next few days, leaving a pattern where there is increasing surface to 850 MB easterlies, due to a building low level ridge to the north, and increasing mid to upper level westerlies. not only will the shear pattern become even less conducive, but the thermodynamic pattern will as well. The mid level cold pool associated with the 500 MB low was the thing responsible for keeping temperature lapse rates steep enough the meager toots of convection that fired to do so. With the mid/upper trough shearing out, 500 MB temps will warm, and therefore those 74-76F water temps won't be warm enough to sustain the needed instability.

All-in-all, what you have is poor to marginal-at-best conditions that will only get worse. I foresee DeForest Kelly making an appearance in the not too distant future.

Chances of it getting named are approaching zero now. Bones is approaching the microphone.

I never gave it much of a chance from the get-go. Too many negatives going against it. Bring out BONES is all I have to say.

The EPAC system looks much more impressive, though it is quite close to land. It does seem to have a much better shot than 90L.

Still there!

[KWT]

Looking quite elongated though, that being said the convection currently to the east of the center could end up giving it just a little more time. The system really can't afford to get any further east because SST's only further decrease which will limit lapse rates even further.
