7-day Snowfall:  March 15-21, 2006

During the 7-day period from Wednesday, March 15, through Tuesday, March 21, 2006...one to two feet of snow fell from western South Dakota, through far southern South Dakota and northeast Nebraska. 

Much of this snow fell during a prolonged winter storm, which lasted from Sunday, March 19, through Tuesday, March 21.  This winter storm prompted the closure of Interstate 90 west of the Missouri River most of Sunday and into Monday morning, delaying teams and fans which were attending the SD State Boys Basketball Tournaments throughout the state. 

Below you will find a map of the 7-day snowfall totals during this time, along with a second map displaying just the 3-day snowfall total for March 19-21.  Click each image for an enlarged view.  A text listing of the daily amounts and totals are available beneath the maps.  Please note that blank entries in the text listing indicate missing data for that day, so some snowfall totals may actually be higher than shown here.
