What I'm interested in knowing is how long it'd take till the
pertubation had grown enough to change the timing and strength of
particular fronts appreciably. If the atmosphere really is a chaotic system
(isn't it?) won't a small perturbation grow?


No, it might grow or it may not, and it will be difficult to find out.

Yes, it really would depend on the environment in which
the perturbation is introduced. If it's a cold, dry, winter
air mass, for example, under strong NW'ly flow -- oops, I see
it's in May. Okay, still, nice cP airmass, low humidity,
very stable, then the perturbation really won't grow much
with time, and any effects will damp out. If there's a weak
storm moving through an unstable environment, then
it is possible that the perturbation will affect things.
