A large storm brought heavy rain and historic late season snowfall to the Black Hills region May 20-22, 2019. A powerful low pressure system slowly moved from the Four Corners region northward through the Plains during this time, leading to a prolonged period of precipitation to western South Dakota and northeastern Wyoming.

Precipitation type throughout the event was largely dependent on elevation. Locations on the plains north and east of Rapid City saw predominantly rain, while higher elevations in the foothills just to the west and south of Rapid City and the Black Hills received several inches, or even multiple feet, of snow.

For the Black Hills and western South Dakota plains, this three-day period was among the coldest, wettest, and snowiest stretches on record over the latter half of May, with several temperature and precipitation records set.
