Weird weather phenomena are currently increasing in the US skies.
Look at these giant roll clouds tumbling across the sky from Texas to Oklahoma on January 16 and 17, 2016.
After the cross in the sky in Michigan and the full circle rainbow in North Carolina, these rare and beautiful roll clouds were spotted sweeping throught the sky of Texas to Oklahoma on January 16 and 17, 2016.
Roll clouds are just one of the weird weather phenomenon that can happen when winds go wild.
Here a video showing the rare cloud formation over Norman, Oklahoma:

Roll clouds are a type of arcus cloud, which is a category of low cloud formations.
These tubular clouds sometimes form along with storms born out of the storm’s downdraft.
This roll cloud was filmed over Houston, Texas, on January 16, 2016:

Sinking cold air causes warm, moist air on the planet’s surface to climb to higher altitudes, where the moisture condenses into cloud form.
Winds from the storm “roll” the cloud parallel to the horizon, creating an effect that looks much like a horizontal tornado.
And that video shows them in College Station, TX on January 16, 2016:

Rolls clouds are completely detached from the bulk of the storm. Therefore they aren’t dangerous in themselves.
Also stunning are lenticular clouds which also form because of the vagaries of winds around mountain peaks.
