Billings is expected to see its first measurable accumulation of snow this week, possibly as early as Wednesday, according to the National Weather Service.
Today will be cool, sunny and mostly clear, with NWS forecasting a high temperature of 39 degrees and an overnight low of 26 degrees. Tuesday is expected to be warmer, with the weather agency predicting a high of 53 degrees in the city, before temperatures cool down into the upper 30s overnight.
Billings won't see snow until Wednesday at the earliest, said NWS meteorologist Joe Lester, but areas farther west and higher elevations could receive some snow accumulation beginning Tuesday evening.
The mountains around Cooke City are likely to see 6 inches to a foot of snow through the night, Lester said, while lower accumulation totals are expected in the mountains around Red Lodge.
In Billings, rain showers are again likely Wednesday, with the possibility of snow in the forecast Wednesday afternoon through Friday morning.
"I think the pattern definitely will persist, if we don't catch it Wednesday, Wednesday night, sometime by the end of the week we'll catch some measurable snow," Lester said.
Farther west, snow accumulation of up to 2 inches between Tuesday night and Wednesday night is more likely in Red Lodge, Cooke City and Livingston, according to the NWS.
From Tuesday afternoon through Tuesday night, hazardous crosswinds are also likely from Livingston east to Springdale.
