Now that Beryl is wrapping up, looking ahead on the 0z runs of the EPS and GFS, nothing of note for next 15 days.

Nothing exciting with the MJO either.

GFS showing a lot of activity coming off the coast of Africa for the rest of this month but showing nothing developing.  Just ordinary rainstorms.

This feature doesn't model well by NHC noted some pretty strong winds associated with it. 

An eastern Caribbean tropical wave is near 66W from N of Puerto
Rico to central Venezuela, moving W at around 15 kt. Scattered 
moderate to isolated strong convection is noted from 13N to 23N 
between 63W and 70W. Recent scatterometer data measured winds to 
40 kt within the strongest convection near 21N67W.

A look at the Saharan Air Layer

Still looking at dust and dry air over the Eastern Atl, but the Western Atl is moistening up.

Looking forward at humidity anomalies 

Today

30th. Granted as time goes out the models smooth things out.

So where is this hyperactive hurricane season?? I am bored!

Plenty of activity coming off the coast of Africa, but nothing that will come about.  Still early in the season, lots more time to go.

You have all that dust from the Saharan Air Layer (SAL) - some say Sarahan Dust Layer (SDL) - which is going to temper things a bit till Augustish. Sit back... Stew is boiling. ACE and SSTs are dreadfully high this year.

Some chatter about things changing in August. MJO looks that way.  And now the EPS is putting things together in a couple of runs

🤔

I will say, considering that it tries to take the VortMax over Hispanola and Cuba AND still have it relatively intact to become an Atlantic Strait/GOM TC, seems a  bit "against the grain". 

The graphic that StretchCt posted does indicate a Non Zero potential for the basin. 

Might be a good test for "the King" - to see if it's regained some of it's, seemingly lost luster, ability to sniff out the LR correctly.

NHC gives it a mere passing mention...

 

For the forecast west of 55W, the Atlantic high pressure will dominate the forecast waters through Sat, then will shift eastward ahead of a weak cold front moving off the Carolina coast. The front will stall of northeast Florida Sun, then dissipate Mon. The pattern will support fresh to strong E winds off Hispaniola through Sun, and gentle to moderate breezes elsewhere into Tue. Looking ahead, winds and seas may increase northeast of the Leeward Islands by late Tue associated with an approaching tropical wave. $$ Christensen
