The shear continues to keep Isaias completely in check, it can't wrap up. The moisture envelope is actually expanding but the feeder band inflow is too weak to provide any power. The thunderstorms rise up only to be cut down before they can get embedded into any rotational pattern. Thus the pressure never drops leaving the winds too weak to draw in more fuel. So the storm can't consolidate any of the available moisture from the Gulf Stream. The pattern from the last 48 hours has remained - all the strong weather is in the NE quad where it spins off without ever getting draw into the core. Freeport is in the worse of it right now and the wind is only 30 with gusts to 45 MPH.
I guess at some point the center might get close enough to the FL coast that some of those stronger bits could come ashore but even then your looking at TS gusts at the most. What we have here is just a blob of clouds with patches of heavy rain and no real organization which would lead to strengthening. The dry air continues limit outflow so the whole thing can't vent properly. Its a zombie... a dead storm that continues on its forecast path dragging its broken limbs along the ground behind it.
