A significant snowstorm brought heavy wet and record snowfall to Southern Montana. As an upper low dropped south into southern Nevada Friday, October 10th, before making a turn to the northeast reaching Eastern Montana on October 12th, persistent overrunning and upslope flow brought a long duration snow event to the region. Snowfall began in many areas on the evening of Thursday, October 9th and continued through Sunday, October 12th. The most intense portion of the storm with the heaviest snowfall rates occurred Saturday night October 11th into Sunday morning October 12th as the main upper low ejected out across Montana. With the high water content of the snow, many large tree limbs and power lines were brought down by the weight of the snow. Temperatures were also well below normal for this time of year.
