Wider weather episode
The seasons first winter storm occurred across the Beartooth/Absaroka foothills and adjacent plains. The coldest air of the season ushered in high temperatures in the 30s and 40s. This combined with a moist, upslope flow, brought accumulating snow to portions of the Billings Forecast area. Trees were fully foliaged, so the heavy, wet snow resulted in numerous downed tree limbs which also resulted in downed power lines.
