An interesting cloud sighting over Regina excited many on social media Thursday morning.
At 6:30 a.m, people started posting photos of an eerie looking arcus cloud rolling over the city. This particular cloud is known as a shelf cloud, which is often seen on a stormy day.
Shelf clouds are wedge shaped and appear at the leading edge of a thunderstorm. They are formed by the outflow from a developing storm cell.
Another type of arcus cloud was spotted north of Melville, Sask. by Colleen Schofer early Thursday afternoon. Roll clouds are formed when warm, unstable air moves over cooler air and winds start to shift while changing speed. This causes the cloud to “roll” and take on a cylindrical, rolling pin type shape.
There is potential for thunderstorms and severe weather in eastern Saskatchewan Thursday. If you capture any interesting clouds that you’d like to share, send them to tiffany.lizee@globalnews.ca
