It’s official: Indianapolis meteorologist Angela Buchman is joining WTHR, the NBC affiliate, next year.

Buchman signed off from rival WISH, the CBS affiliate, last month. The long-rumored move, officially announced today by WTHR, will happen in September 2013, when Buchman’s non-compete clause with WISH expires.

In a statement announcing the move, WTHR news director Keith Connors said Buchman’s hire “underscores our long-term and on-going commitment to being the leader in weather coverage.”

“Angela will make a significant contribution to our team and to keeping Hoosier families safe from the storm,” Connors said. “I couldn’t be happier that she will be joining us.”
