Atlantic Blobette: August 20, Update A

Just in time for the weekend (typical)... there's a rather large and not well defined blobette way out there, around 10N, 25-30W, in the eastern Atlantic. This one, unlike some of the previous jejune 'storms' we've had, looks like it may develop if it can pull itself together (geographically speaking) instead of being spread out over such a large area. It has some 'eastern promise'! ;-) And finally! I've been waiting to use 'jejune' in a sentence. Oh happy day! :-)  
There is some nice vorticity (circulation) in the lowest half of the troposphere (say in the lower 5-7km), and there's quite a bit of convection in the mix already. Wind shear is low and there doesn't appear to be too much dry or dust-filled air in the immediate vicinity, so we'll see how this one progresses. It's very early days at the moment so no point thinking about the track really, other than it's going to be moving generally westward for a few days.
I'll watch it, but won't send another update unless I can weave in another cool word or er... I suppose if something interesting happens to this blobette.  So probably tomorrow! ;-)
Ciao for now,

If you are making an evacuation decision, please heed your local emergency management and the National Hurricane Center's official forecast and the National Weather Service announcements. This is not an official forecast. If I was there and was going to "run away, run away" (Monty Python), I'll let you know.
