Being accompanied by rain, how can lightening cause fires?=?

A dry thunderstorm is a thunderstorm that produces thunder and lightning, but most or all of its precipitation evaporates before reaching the ground. Dry lightning refers to lightning strikes occurring in this situation. Both are so common in the American West that they are sometimes used interchangeably. The latter term is a technical misnomer since lightning itself is neither wet nor dry.
Dry thunderstorms occur essentially in dry conditions, and their lightning is a major cause of wildfires. Because of that, the National Weather Service, and other agencies around the world, issue forecasts for its likelihood over large areas.

Ah, lightening is certainly less likely to cause fires if it is in fact accompanied by a drenching rain. At least whatever fires it might cause will be quelled right away so the fire doesn't spread to become a major disaster.
But here's the rub...actually several rubs. Not all lightening storms are accompanied by rain. They are called dry lightening storms where the clouds gather and create the bolts but the rain does not reach the ground (it's called virga).
Second, when there is but a slight rain following a long period of drought, there is still dry tinder under the surface layer of wetted growth. So that dry tinder will catch fire even though there is a coating of moisture from the recent rain.
But in general, you are right...we in California welcome the rainy season because we know the number of wildfires will be drastically reduced during the season.

Dry lightning causes the fires.
