A National Weather Service meteorologist said there is a slight chance for a white Christmas.

Meteorologist Jane Fogleman said Gallatin, Madison and Beaverhead counties could see snow accumulation of 3 to 6 inches at higher elevations and 1 to 2 inches at lower elevations on Tuesday. The weather service issued a winter weather advisory until 10 p.m. Tuesday for those counties.

Fogleman said commuters should plan for slippery road conditions.

“It’s enough that we’re anticipating it to affect traveling,” Fogleman said.

She said there’s a 30% chance of snow on Christmas Day, mainly before 11 a.m., but that little or no accumulation is expected.

For the rest of the week, Fogleman said, we should expect to see partly cloudy skies, dry conditions and highs in the 30s. As we head closer to Sunday, she said, the temperatures are expected to reach up to 39 degrees.

Fogleman said there is slight chance of fog Tuesday and Wednesday mornings.

“It could also be after the snow falls on Tuesday and there’s moisture on the ground,” Fogleman said.

She said people getting outside and enjoying the recent warmer weather should be aware that overnight lows are expected to drop into the teens.

“There are concerns of hypothermia and frostbite as the temperatures drop here,” Fogleman said.

Fore information on road conditions, drivers can call 511. Travelers could also check the Montana Department of Transportation’s website for driving conditions.
