Expect mountain passes with high elevations above 6,000 feet, like Homestake Pass outside Butte, to have snowy conditions on Tuesday morning, according to the National Weather Service.
“It’s looking more likely for people to encounter snow while driving,” said meteorologist Jeff Kitsmiller from the National Weather Service on Friday. “This could catch many off guard at this time of year.”
Western Montana is forecasted to experience widespread precipitation and a winter storm watch in higher elevations at the beginning of next week, he added. Elevations above 6,000 feet are expected to see snow on Monday going into Tuesday, and Kitsmiller advised those planning outdoor activities in the backcountry to be prepared for winter conditions or to consider adjusting their plans.
Snow in June is not unheard of in Montana, but it could be unusual if it reaches lower elevations. Kitsmiller reassured that floods are not a concern as the rivers have sufficient capacity to handle the precipitation.
The valleys could also see some snowfall, Kitsmiller mentioned, similar to the few inches of snow experienced in May.
“It’s a possibility,” Kitsmiller of NWS Missoula, remarked.
Kitsmiller explained that the May snowfall caused significant tree damage due to the trees already having leaves, and this event could be more severe as the trees now all have their leaves.
“One of our concerns would be tree damage and power outages,” he stated.
While Montanans are accustomed to snow in any month of the year, Kitsmiller noted that snow in June typically stays at higher elevations. However, this system may bring snow levels lower than usual for mid-June in Montana, indicating it could be a rare event occurring once every five or ten years.
Additionally, abundant rain and snow could help mitigate the fire season, preventing the state from drying out too quickly.
“A widespread rain event would be very beneficial,” Kitsmiller emphasized.
An outlook report from the U.S. Department of Agriculture published in early June indicated that recent weather conditions have improved overall water supply, although certain parts of the state remain below normal in terms of precipitation, including the Kootenai, lower Clark Fork, Jefferson, and Upper Madison river basins.
He advised individuals planning to engage in activities in higher elevations to be prepared for obstacles such as fallen trees blocking roads and also warned that snow might hinder their ability to descend safely.
Backpackers should be equipped with winter gear and layers to stay warm and prevent hypothermia.
“It would be best to postpone plans and avoid going out if possible,” Kitsmiller recommended.
