Overview

On February 24th through 25th, 2020, an elongated area of low pressure moved slowly from eastern Montana through South Dakota. Significant moisture was ingested into the system, resulting in moderate to heavy snow across northeastern Wyoming into western South Dakota. Upslope-enhanced snow developed over the northern and northeastern Black Hills and foothills, where up to 31" of snow fell over two days. Several inches of snow fell on the surrounding plains. Thankfully, strong winds weren't much of an issue with this storm, although some breezy northerly winds created some patchy blowing snow and reduced visibility at times.
