The first severe weather event of the season across northeast/central South Dakota took place on the afternoon and evening of Sunday, May 22nd. It involved a few severe wind/hail reports as well as a brief landspout tornado. It was part of a much larger, broader outbreak of severe weather that stretched from Canada to Mexico, as seen at the right.

The severe weather season began unusually quiet across the area. This event led to the first NWS Aberdeen Severe Thunderstorm or Tornado warning of 2016 across our County Warning Area, which tied a record for latest first warning to start a season (since 1986).
