Glacier National Park and the northwestern regions of Montana are bracing for significant snowfall this weekend, just as summer officially begins. A classic case of “Authentic Montana” weather is in full swing, with up to 12 inches (30 cm) of heavy, wet snow expected in the higher elevations above 6,000 feet, including key areas like Logan Pass and Going-to-the-Sun Road.
Winter storm watch in effect for Glacier National Park
A Winter Storm Watch has been issued from Saturday afternoon through Sunday morning, affecting elevations above 4,000 feet, with the heaviest snow forecasted for areas over 6,000 feet. That includes major travel routes and mountain passes like Marias Pass, Polebridge, and the backcountry of Flathead National Forest.
Travel conditions could deteriorate quickly
Even lower elevations around 4,000 feet could see up to 4 inches (10 cm) of snow, leading to sloppy and hazardous driving conditions. With Going-to-the-Sun Road having just reopened, this early-summer snow could cause closures and unexpected delays, especially for visitors unfamiliar with winter mountain driving.
Moderate to major disruptions possible
The chance of moderate to major impact is currently estimated at 50% or higher, meaning considerable disruptions are likely. Snow loading on trees poses the risk of downed limbs and power outages, especially in remote forested areas. Travelers and park visitors should prepare for the possibility of infrastructure interruptions, including road closures.
Stay alert through Sunday morning if you’re heading into northwest Montana, particularly in the Glacier National Park region, as this unusual June snowstorm sweeps through the high country.
