The rarest of the rare~ Positive lightning makes up less than 5% of all strikes. It originates in the upper levels of a storm, the amount of air it must burn through to reach the ground usually much greater and its electric field typically is much stronger than a negative strike. The flash duration is longer, and its peak charge and potential can be ten times greater than a negative strike; as much as 300,000 amperes and one billion volts. (NWS quoted)
