Thunderstorms are forecast for your area. Cloud conditions might be right for producing strikes in the next few days, though lightning itself cannot be forecasted.

Lightning is a visible electrical discharge produced by a thunderstorm, based on the build up of oppositely charged particles within a cloud and from cloud to ground.
