Overview
|
A significant late winter/early spring winter storm impacted during the second week of April. The strong low pressure system brought snow amounts measured in feet to areas of central into northeast South Dakota. Significant freezing rain and icing was observed in portions of southeast South Dakota, southwest Minnesota and northwest Iowa. Additionally, thunderstorms produced small hail and plentiful lightning to some areas. Strong winds during the event resulted in blizzard conditions in areas that received the heavy snow and numerous power outages in areas that received icing. |
