Because an ordinary storm cloud keeps negatively charged particles between the positively charged particles and the ground, positive lightning doesn't usually happen unless there's a strong wind to move the negative charge out of the way, or once most of the storm has cleared.

Positive Lightning FAQs:

What is a positive lightning strike
The previous section describes what is called "negative lightning", because there is the transfer of negative charge from the cloud to the ground. However, not all lightning forms in the negatively charged region under the thunderstorm base. ... Positive lightning makes up less than 5% of all strikes.

Why is positive lightning more dangerous?
With lightning this means there is a transfer of a negative charge from the cloud to the ground in negative lightning strikes. 90-95% of all lightning is negatively charged. It is very dangerous and a typical negative charged bolt is about 300,000,000 volts and 30,000 amps of power.

What causes lightning?
Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark - lightning - occurs between the two charges within the cloud.

Does lightning go up or down?
The answer is both. Cloud-to-ground lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts. Objects on the ground generally have a positive charge.

Can lightning kill you?
You're dead. First, lightning injures more people than it kills. In fact, approximately 90 percent of those lightning hits survive, but often with long-lasting neurological damage, says Dr. Mary Ann Cooper, a leading expert on lightning injuries.
