(SOUTHERN COLORADO) — Thunderstorms are expected again over Southern Colorado on Friday, and some of them are going to be strong.

There’s a lot of wind shear in the atmosphere today, and that is going to help storms rotate. When storms spin, they organize and strengthen. The spin in the storm’s updraft helps it to stay separate from the downdraft — this often results in large hail, and that is our biggest threat today.

Most of the storms will move east, but any that start to turn to the right, and start heading east-southeast or southeast, may become capable of producing a tornado.

A severe thunderstorm and/or tornado watch will likely be issued for parts of Eastern Colorado later on today.

A WATCH means that ingredients are present for the possible formation of severe thunderstorms, and you should pay attention. It’s similar to Mom or Dad putting the ingredients for tacos out on the kitchen counter – get ready. A WARNING is like the tray of assembled tacos arriving at the table – it’s time to take action! Know the difference and be ready later today.
