6 hour Forecast of Chance of Lightning

Chance of Lightning represents the probability of a cloud-to-ground lightning strike being observed within 20 km (roughly 10 miles) of the forecast point.

This product is calibrated with cloud-to-ground lightning strike data, so it may miss intra-cloud lightning that causes thunder.
