JACKSON, Wyo. — Another powerful storm is heading toward Jackson Hole to cap off what has been one of the snowiest months on record above 9,000 feet in the Tetons. A Winter Storm Warning is currently in effect for all of Teton County from 9 p.m. Thursday through 6 a.m. Saturday.
After a quiet (and cold!) start to the day on Thursday, clouds will increase during the afternoon with the first flakes arriving late in the day. Snow will then pick up in intensity on Saturday night with new snowfall of 4-8 inches expected across the Tetons by early Friday morning and 1-3 inches in the Jackson Hole Valley.
Periods of heavy snow are expected throughout the day on Friday and into Friday night, and strong winds will cause major travel issues all day with blowing snow and near whiteout conditions at times. West/southwest winds will gust to 30-40 mph in the valley and 50-60 mph in the mountains.
Additional snow amounts from Friday morning through Saturday morning will range from 8-16 inches in the Tetons and 2-5 inches in the valley, bringing two-day totals to 1-2 feet in the Tetons and 3-8 inches in the valley. Western portions of the valley near the base of the Tetons (Wilson, Teton Village, etc.) could see isolated amounts of higher than 8 inches as well.
On Saturday, travel conditions will start to improve with decreasing snowfall rates and lighter winds expected. Additional snow showers on Saturday will result in another 1-3 inches in the Tetons and a dusting to a half-inch in the valley.
Following this storm, dry conditions are expected on Sunday with mostly sunny skies and chilly temperatures, followed by a warm-up next week.
