First Snow of the Season Blankets Higher Peaks of Utah, Wyoming, Including Yellowstone and Grand Teton National Parks
Published: September 11, 2019
Mother Nature is providing a winter tease in some areas this week. With more than a week of summer still left to go, some of the higher peaks of Utah and Wyoming, including Grand Teton and Yellowstone National Park, are seeing their first snow of the season.
This first "fall-like storm" of the season, as the National Weather Service in Salt Lake City referred to it, brought a light accumulation of snow Tuesday morning at Bald Mountain Pass in the Uinta Mountains of northeastern Utah, about 50 miles east of Salt Lake City.
Wednesday morning, snow dusted the higher peaks at both Alta and Park City, Utah.
Snow was expected to develop in the higher terrain of northern and western Wyoming into Wednesday.
According to the National Weather Service in Riverton, Wyoming, about 1 to 4 inches of accumulation was expected above 8,000-feet elevation in the Bighorn, Wind River and Teton mountains, including parts of Grand Teton and Yellowstone national parks.
A winter weather advisory was posted by the NWS for the Beartooth Mountains of southwest Montana, where 6 to 8 inches of snow was possible above 8,000 feet elevation through early Thursday morning.
A couple inches of snow were also possible above 10,000 feet in the high country of northern Colorado, mainly north of Interstate 70, according to an early-morning forecast discussion from the NWS Boulder office.
Forecast Snowfall Through Wednesday Night
The snow likely won't last long. A warmup is in the forecast later this week.
September snow is common over the higher terrain of the Rockies.
The village of Moose, Wyoming, located in Grand Teton National Park, averages 0.4 inches of snow each September.
Denver (Sept. 3, 1961) and Salt Lake City (Sept. 17, 1965) have picked up measurable snow in past Septembers.
Most lower elevations of the Rockies and High Plains typically see their first accumulating snow by October.
November is the month this usually happens in much of the Midwest and Northeast, except along the Interstate 95 corridor, which typically waits for its first accumulating snow until December.
