For a first approximation I'd add a velocity in a random direction to each
fragment's forward velocity at the point of the explosion, and then let gravity
control them from then on. As others mentioned, any fireball or smoke/fine
particle cloud will likely stay virtually stationary at the point of the
explosion until it dissipates. With some tweaking this would probably look good
enough for most purposes. A simple wind resistance factor (a decelerating force
proportional to existing speed squared) could also be calculated for each
fragment for added realism.

I hope it looks good, this is something I keep meaning to try!
