Overview
|
A low pressure system moving through the Central Plains brought an initial wintry mix of freezing rain and snow to the area on Friday night. The freezing rain led to slick roads, especially over east central South Dakota Saturday Morning. Meanwhile, heavy snow was falling farther to the west and continued throughout the day on Saturday. Areas north of Highway 212 received 6 to 12 inches of snow by the time the snow ended Saturday night. South of Highway 212, snowfall amounts were generally in the 3 to 6 inch range. In addition to the snow, wind increased through the day on Saturday, with gusts in the 30-45 mph range. The combination of the falling snow and blowing and drifting snow led to poor travel conditions across northern South Dakota and west central Minnesota. |
