Please use these forecasts for planning travel!
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. 

Here is the forecast snow to 7pm Monday. 

More snow is forecast to fall after that time. The map below is the probability of 4" or more of additional snow until 7am Tuesday. 

Below Are Forecast Radar Images
The blue represents falling snow, with the darker colors representing heavier snow. This is for 7am Sunday. 

7pm Sunday radar.

Power outages may occur in this areas. Deep blue i...
