Snow will start to build across SE MN and NE IA Wednesday evening. Snowfall is expected to continue through Thursday morning. Snowfall amounts WILL NOT be the major issue with this system. The major problems will be strong winds and dangerous wind chills. Winds will be around 25-35 mph with gusts reaching around 40-50 mph Thursday and Friday. This will cause blowing/drifting snow and whiteout conditions.
