Winter arrived in the Treasure State over the past couple of days, thanks to a September storm that brought snow to higher elevations over the weekend.

Time lapse video from a webcam in Big Sky showed a blanketing of white that occurred on Saturday and Sunday, after some snow showers fell across several areas of Montana.

From the photos posted on the Big Sky Resort's Twitter page, you can see the snow covering some signage around the resort, and what looks like a couple of inches of accumulation in a wooded area.

There was enough accumulation for Frosty the snowman to appear near the ski lift at Big Sky on Sunday (9/19), and there's more snow possible through Monday (9/20), according to the National Weather Service.
