My description was poor. Here is a link to some pics of the effect.

The discharges are bright and easily observed even during the daytime.
Obviously at night with a black sky the effect is spectacular.

The whole discharge path glows again as the tendrils branch in to more
distant parts of the cloud.
With one distant storm occasionally you could observe the growth in three or
four stages as the discharge progressed horizontally.
