According to Ask Ausiello, Barry will be facing troubles of the time traveling variety in the fifteenth episode of The Flash.

“There’s an unexpected, accidental time travel coming up,” executive producer Andrew Kreisberg explained. “And it is played both for hilarity and darkness. It happens in an episode we’re really excited it — the first Weather Wizard episode with Liam McIntyre.”

McIntyre has been cast as Mark Mardon, the Weather Wizard.

Mark Mardon, brother to Clyde Mardon, returns to Central City to get revenge for his brother's untimely death. Mark uses his powers, similar to Clyde's ability to control the weather, to go on a rampage to find the man that shot Clyde...Joe West.

The fifteenth episode is currently untitled but McIntyre is also featured in the sixteenth episode entitled Rogue Time.

The Flash returns Tuesday at 9 p.m. ET on The CW.
