A dynamic and historic springtime storm system severely impacted the Northern Plains on April 13th and 14th. Widespread snowfall totals of one to two feet across the southern half of South Dakota and southern Minnesota combined with winds gusts of up to 50 mph to produce widespread blizzard conditions for many hours. Additionally, snowfall accumulation records were set, snow drifted to 3-4+ feet in some cases, and severe thunderstorms impacted southeastern South Dakota. Both portions of I-29 and I-90 were closed from the afternoon of the 13th through the morning of the 15th.

Thanks to everyone who reported snowfall amounts and conditions, and shared photos throughout the course of the event.
