What happened

The episode as NWS DLH wrote it up.

Ice accumulations of one-quarter to one-half inch occurred from the International Falls area, across the Iron Range, to the north shore of Lake Superior. The ice caused travel problems due to slippery roads and airport runways. The weight of ice accumulation also brought down tree limbs and power lines, causing widespread electrical outages.
