A powerful winter storm is expected to bring over a foot of snow, strong winds over 50mph, blizzard conditions, and dangerous wind chills starting Wednesday and continuing into Thursday.


Snow will continue this evening for some as the first wave has already impacted some regions of the state. Then the snow will become more widespread, covering much of South Dakota during the overnight hours.


By Wednesday morning, the far northern end of South Dakota may see a break in the action before the main event moves into the area.


By Wednesday evening, widespread snow, heavy at times, will be impacting us statewide. Blizzard conditions are expected at this time, with visibilities down to zero at times, wind gust over 40mph, and dangerous wind chills of 20 to 30 below zero.

The snow is expected to come to an end across the west during the morning on Thursday.


By the afternoon hours, the snow will come to end for central and eastern, South Dakota is expected to be completely gone by Thursday evening.
