The Tetons have already seen a few of small storms that dropped a few inches of snow already this month, but this incoming storm is forecast to be the biggest storm of the season so far.

Jackson Hole’s Cody Bowl webcam is revealing a wintery scene already (photo below) today.

.A strong fall storm system is expected to bring significant
snowfall across the northwestern mountains of Wyoming. The
precipitation will begin early Saturday morning, and continue
through the day Sunday, before tapering off late Sunday. The
heaviest precipitation is expected to occur Saturday and Saturday
night. There remains quite a bit of uncertainty on the placement
of the heaviest precipitation, and the snow levels through the
event.
