...Another dose of snow returning Thursday and Friday...

Moist southwest flow will stream over northwest portions Thursday
afternoon, as a cold front approaches Yellowstone from southwest
Montana. Light snow showers will be possible from Jackson
northward into Yellowstone Thursday afternoon, with the best
chances occurring over southwest Yellowstone. This will continue
into the evening hours, with moderate to heavy snow possible over
the park after midnight. Light to moderate snow will also be
possible over the Tetons by this time. Light to moderate snow will
then spread southward during the morning hours Friday and
encompass the western mountains and valleys through the afternoon.
7 to 10 inches, with localized amounts up to 1 foot, are expected
across Yellowstone. 6 to 9 inches are expected in the Tetons and
Absarokas, with 3 to 5 inches in Jackson Valley and 1 to 2 inches
in Star Valley.
