If you are planning to change planes in Minneapolis (Delta Airlines' hub), you may wish to see if they will route you through their hubs in Detroit or another city. While the Minneapolis airport usually does a fine job with snow, this storm is going to test their abilities. 

Late data indicates winds may be a bit higher than originally forecast, meaning there will be some drifting of the snow.
