Re: ATL: INVEST 95L - Discussion
I think NHC is right on with the 40%. A big convective burst tonight would help out a lot.

As a training exercise we could go look a the mid level moisture maps and wager a prediction.
NHC said less than 50% and I think that is consistent with a slightly dry environment (and no strong convective burst) currently.

Re: ATL: INVEST 95L - Discussion
The eastern part of this monsoon trough may be what ultimately takes over. Convection is more concentrated there now and the latest GFS runs of the parallel and OP develop a good low-level vorticity that tracks WNW.

GFS and GFS-P spit out two vortices. GFS-P below. One is in the South Caribbean and another is further east east of Lesser Antilles:

I agree , the disturbance back around 38 w looks pretty good.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sun Jul 16 2017
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
A weak area of low pressure located about 900 miles east-southeast
of the Windward Islands continues to produce disorganized showers
and thunderstorms. Environmental conditions are marginally
conducive for some development of this system before it reaches the
Lesser Antilles in two to three days. After that time, less
favorable upper-level winds are expected to hinder additional
development. An Air Force Reserve reconnaissance aircraft is
scheduled to investigate the disturbance Monday afternoon, if
necessary.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.

Re: ATL: INVEST 95L - Discussion
Convection back near -38w just keeps building near what I assume is a wave apex?
Could get a LLC to close off and climb up out of the ITCZ there.

2005 was most favorable in the Caribbean.
I wonder where the monsoon trough is normally positioned.

Wide view showing the two suspect area in the monsoon trough. The eastern area continues to build deep convection while the Western area does too. The second image shows the areas of 850mb vorticity. The eastern area is gradually gaining vorticity too. Keep an eye on this eastern area also:

Re: ATL: INVEST 95L - Discussion
I'm leaning towards the eastern area to survive may not develop now but down the road somewhere.
though 95l looks like it will at least make it TD maybe don maybe more .. but it must get started before the caribb.

trailing system may keep the SAL from becoming entrained into the leading system. That may be what HWRF is seeing

Kind of off topic but it seems like it's been ages since I've seen the Atlantic look as juicy as it does today. Hopefully this isn't a indication of what may be to come in the next 3 months.
