Snow/Ice

Due to warmer temperatures, many locations in our southern areas received freezing rain before the snow ever fell. This resulted in ice accumulations of around a quarter of an inch in the southern Red River Valley.

Additional Information

With the freezing rain in this system, we had many areas that lost power. We also had some thunder snow, due to higher CAPE in the area giving the snow showers some instability. Here's a look at power outage maps and the GIF of GOES Product GLM (Global Lightning) during the event.
