By the way, fires started by lightning often start 3-4 days after the lightning strike. They sit there smoldering in/on the ground, building up slowly until a gust of wind gets the into some fuel and away they go.
This may not apply at all to your current situation of course. Best wishes and prayers by the way.
I keep obessive track of weather in the summer. Many summers, in fact most, there are thunderstorms that often have only lightning and little to no wetting rain. Since I Live surrounded by millions of acres of national and state forest, I am obsessive.
In SW OR there have been no thunderstorms at all for a long time. I don’t know if nothern is the same, but when the weather is ripe for t storms, it is usually not just very locally.
