It's a tough day at Channel 10.

On Friday, we are saying farewell to one of our favorite people, meteorologist Mike Witcher.

After ten wonderful years in Knoxville, Mike has taken a job at Weather Nation in Denver. It's a 24-hour weather channel you can see locally on DirecTV.

Colorado is home for Mike, and his wife Janelle, so they are looking forward to raising their young son near their family, but they are sad to leave their Knoxville family behind.

We will miss Mike so much, as we know many of you will. But we wish him well!!

Check out the video above to hear from Mike himself about how much East Tennessee means to him.

And below, see how Mike's Ch. 10 family says goodbye:
