Overview
A vigorous upper level low emerged from the western United States January 1, 2023. As it moved into the central plains, it wrapped up over Nebraska injecting significant amounts of moisture into northeastern Wyoming and western South Dakota. Snow started the evening of January 1 and persisted until the morning of January 3. The heaviest snow fell from Martin to Rosebud to Winner, South Dakota, although there was a heavier pocket south of Hot Springs, SD and south of Gillette, WY. Little to no snow fell north of Interstate 90 over northwestern South Dakota. The one nice thing about this winter storm was that winds were relatively tame. The snow fell straight down at our office in Rapid City, SD.
