The snow started on December 20, 2009 and didn't stop until Dec. 27. During that time, 21.5 inches of snow fell with ten and a half of that falling on Christmas Day.
It made for a December to remember with nearly 28 inches for the month.
There was so much snow and wind on Christmas Day that Sioux Falls issued a no travel alert, that's something that rarely happens.
While computer models were pointing to a storm system much like the one in 2009, they now have backed off on it.
A lot of the information we are seeing now, has the system well to our south and east but they do have very cold air moving in from the north.
