This is partly regarding how the Jarrell TX storm moved--along with its tornado-- SW . . .

At what point and by what factors will a storm's movement have an impact on its structure? In other words, the basic model people are taught with spotting is to expect NE movement with the SW quadrant having the meso and tornado. When might one expect the meso to be in a separate section of the storm based on the movement of the storm? If the steering winds are strong enough for long enough, can this alter the structure in a way that would make a real difference?
If there aren't any answers that elaborate on this previous thread about south-moving storms,
http://www.stormtrack.org/forum/archive/index.php/t-858.html
then I guess this new one is redundant but even if people could narrate some firsthand observations recently that exemplify any of the principles, such as on a south-moving storm how long would it need to be south-moving to want to be on the west, rather than the east. I notice some of the storms in FL at times bob about in various directions, probably with the tug-of-war of West/East coast breezes.
Just was watching one storm (not a supercell though) move S. a bit now moving NE.
