BIGGER Lighting flashes

Went to Bartville for more paint and wood. The most the roads here in Oklahoma are narrow two line country roads that are windy. We start back home after dark to Pawhuska. The rain start pour down in bucket. Best way to see the road in my head light was on dim til the lighting struck then it lite up the sky,road and countryside for miles.
We drive away then the lighting struck again so we could drive little faster because it was like daylight for a few second. Showing where the curves and straight part of the road were. We got home safely.
There was a saver storm warning on TV and a tornado watch. They could not say were it was because it was the weather for forming them. They thought they might have one forming in skitook about 30 mile south of us. It started forming a hook shape. The storm pass on without forming a circle. We got a cellar by the house. Only we still do not know were the door is. We have to look tomorrow after the storm.
