I remember it hailing here in 2007 & 2008.

"They showed that smoke from these fires delays the release of water from clouds in the form of rain, thus preventing depletion of the water in the clouds as they grow. As these water-laden clouds reach great heights, they produce thunderstorms and hail instead of relatively moderate rain."
