One day at my work place, I noticed it was getting dark to the north.
I went to my radar app and saw that there was severe thunderstorms, north of my county. I kept on eye on the weather as I continued to work. A couple of minutes later, I noticed the clouds changing shape.
I looked up and saw some clouds, that was indicating instability in the atmosphere.

What these cloud formations are called: Mammatus Clouds. They are usually seen with severe weather thunderstorms, including tornadic thunderstorms.

Thankfully, the severe weather stayed away. But, the counties above us, had a TON OF RAIN in a matter of a few hours. Some counties got between from 2 to 4 inches!! Which in a way was good. The counties above us for the last few days were under fire watches.
