. As I recall, there is a ground to cloud stroke, and the cloud to ground
. follows.

 I seem to recall reading that what we perceive as a stroke, is really
 multiple surges of current, back and forth between ground and cloud.
 The first surge opens a path (kind of), and subsequent surges follow,
 until some sort of charge equilibrium is reached. My guess is that it
 might be a large RC circuit, which is pulsed and then oscillates.
