A Rare Visit by a Thunderstorm

Sunny days give rise to a warm ground and rising air. As it rises, air parcels cool until possibly the water vapor in them condenses. The fair weather cumulus clouds we see in the afternoon originate this way.

Occasionally, this can lead to cumulonumbus clouds and thunderstorms. This is what happened over NearSys Station today. Here is a collection of what I saw.

Understand, this cumulonumbus had a wall cloud.
