As of this writing, WBIR shares that Mike will remain in the East Tennessee area, but there is no word on his joining another network or taking a break from meteorology.
Mike has been pretty vague about what’s next too. However, in his Instagram post, he mentioned his passion for “flying airplanes and brewing beer” in addition to his passion for the weather, so maybe he'll decide to take a breather from meteorology for a bit.
Given that Mike is staying local, perhaps he'll return to the small screen in due time!
