The Twin Cities' top-rated morning show is doing the ol' switcheroo.

Meteorologist Matt Brickman and traffic reporter Kim Johnson will join current anchors Jason DeRusha and Jamie Yuccas at "WCCO 4 News This Morning" starting Sept. 1.

Brickman will take over for Mike Augustyniak who, in a statement released by WCCO, said he asked for a reassignment.

"My body doesn't work as well at 3 a.m. as it does at 3 p.m.," he said.

Current traffic reporter Natalie Nyhus will become anchor of the Saturday morning show, the gig currently held by Brickman.

"After four awesome years on mornings, I was ready for a new challenge," Nyhus said.

In a letter sent out to staff, news director Mike Caputa reiterated that the changes were made at the requests of Nyhus and Augustyniak.
