After an incredible stretch of warm weather during the middle of February, winter returned with a blast bringing widespread 6 to 12 inch snowfall reports to end the week. The heaviest snowfall had fallen across areas along or south of the Interstate 90 corridor, with upwards of a foot of snow from Valentine, NE northeast through Yankton, SD, Sioux City, IA, and Spencer, IA.  

Compounding the heavy snowfall were strong winds in excess of 40 mph that created near blizzard to blizzard conditions across the Tri-State region.    Roads were significantly impacted with no travel advisories in many areas. 


This storm broke one major record as it moved through. In Sioux City, 8.2" of snow had fallen on Thursday February 23rd, breaking the previous daily snow record of 5.5" set back in 1924.
