Rain could switch over to snow in Billings as early as this afternoon, according to the National Weather Service, but the city is unlikely to see any accumulation until Wednesday night.
Fresh powder has already begun piling up in the mountains, with 18 inches reported since yesterday in some locations in the Crazy Mountains and several inches throughout the Beartooths, said Joe Lester, a meteorologist with the NWS office in Billings.
Snow has already begun falling in Red Lodge, and Lester said the town could expect 3 to 6 inches today and tonight, with upwards of 10 inches falling on the ski area through tomorrow morning.
In Billings, falling temperatures overnight could create slick conditions on area roads Thursday morning, but Lester said tonight's commute is unlikely to be affected.
Today's temperatures are expected to peak at 43 degrees and fall to 26 degrees overnight.
"The roads in town are going to stay wet," he said. "Light snow is possible through the night tonight, so the Thursday morning commute could be a little slick."
Scattered snow showers are possible in town through the weekend. All told, Lester said Billings is unlikely to see more than a few inches of snow, with the best chance of accumulation expected on Saturday.
