The storm began on Wednesday when it spread disruptive snow over the northern Sierra Nevada, including Donner Summit, California, before shifting over the interior southwestern United States.

During Wednesday evening, parts of the valley around Las Vegas picked up over 4 inches of snow. Travel became slick and treacherous in the surrounding area as a result.

Schools in Las Vegas were closed on Friday due to the recent snow and freezing conditions.

Snow was seen falling near the mountains surrounding Los Angeles on Thursday afternoon, including in Pasadena and West Hollywood. The snow did not accumulate, but people went outside to see the unusual snow fall from the sky.

On Thursday, Interstate 5 at the Grapevine in Southern California was closed as snow created difficult travel.

While snow has ended in California and around Las Vegas, it will continue to pound Arizona, New Mexico and Colorado into Friday night.
