I hear that about stronger and weaker systems. It's a reason I have a problem with the model that shows it as a strong system moving west slowly.

Timing is everything.

Also, beginning to wonder how much of an effect the stronger ULL off the East Coast of Florida will have to do with the steering currents as that ULL seems stronger now than it has been...though I could be wrong.

Sort of pops out today with a major spin.

Also, the dry air to the north of the storm seems to be filing in ... also a possible factor.
