I was pretty conservative on first call because I'm not in the habit or forecasting 160mph gusts and 3 feet of snow at 4 days lead time, but if you read the blog, I implied exactly what you are referring to. You are spot on in that the timing of Laura's evolution is going to leave little time for modulation via internal processes (ERC), which may be the coast's only hope under these circumstances. Texas would likely have been better off had Laura blown up near the leewards and 1) Began ERC 2) Been a mature, coupled system upon traversing of Hispaniola and Cuba, which would have rendered it more prone to disruption.
