The worst lightning strikes today are mostly not in California: However, here it might only take one bad lightning strike to set off a really big fire in California

 I'm looking at a lightning strike map and they start around Louisiana and Texas and northern Mexico and go through New Mexico and Arizona, Nevada and Colorado, Utah and Idaho. That's where the worst lightning strike activity tends to be today. There is some lightning coming down along the California-Nevada border though too. California is such a dry tinderbox it likely is only a matter of time before we get some lightning strike fires happening here if the fire resources are in place somewhere else at that time.
