So how does lightning start a fire when there's "not a cloud in the sky?"

Lightning strikes don't always generate enough heat at the time of the strike to support open flaming, especially if rain is present in the storm.

Not all lightning strikes cause a fire, but if there is enough heat a "smoldering fire" may start, which typically emits little to no smoke.

As the fuels dry out and the heat increases, there comes a point when the smoldering fire progresses into open flames. It's at this point that enough smoke is emitted to become visible.

Fires may smolder for days before active burning begins, hence the reason that a lightning-caused fire may start burning on a sunny and clear day…
