Lenticular Over Reno.JPG

Did you see a strange-looking cloud in the sky over Reno on Wednesday night? If you did, you aren't alone.

After receiving a call from a viewer about the odd cloud, 2 News Nevada Chief Meteorologist Chris Larson shared that what the viewer saw is called a lenticular cloud.

"A lot of people call them spaceship clouds, saucer clouds or even pancake clouds," Larson said.

They are caused by winds rolling over the Sierra.

The wave-like motion of the winds up and over the mountain and then down on the backside creates waves where lenticular clouds form.

This means that many times the cloud formations seem to be standing still.

When these clouds build on top of one another, they are called stacked lenticulars.

According to Larson, northern Nevada is one of the best places in the world to see them.
