I wouldn't write this tropical wave off yet. I've been looking at the GFS run this evening and there are a couple of interesting features; one being the mid-continental subtropical upper ridge setting up shop over the Mid-South and a piece of the Bermuda sub-tropical upper ridge off the coast of FL with an inverted upper trough near FL sandwiched between the two ridges aloft. Wind Shear in this entire area is quite light. It's something to keep an eye on as we go forward in time. The upper pattern isn't expected to change very much for several days and in fact the GFS at H+120 hours has a vorticity max in the Eastern Gulf of Mexico.
