East Tennessee has seen its fair share of frigid temperatures, but January 21st, 1985 brought an arctic blast our area had never experienced before.

If you think it's cold outside right now, that's nothing compared to what it was 29 years ago Tuesday.

On January 21, 1985, it was negative 24 degrees in Knoxville! That is our all-time record low.

It was so cold, the pipes burst at the Sunsphere, and water spewed everywhere. The next day icicles were hanging down from the iconic building.

It was colder in Knoxville that day than it was in International Falls, Minnesota.

That record cold day was one of our Straight from the Heart Moments from 2013, and that video is attached to this story.
