The funnyman, who plays weatherman Brick Tamland in the hit comedy and its new sequel, was being interviewed on the morning news programme when he took his chance to tell viewers about the daily forecast.
Interrupting the show's weather girl Laura Tobin during her segment, he explained Britain could expect heavy fog and clouds, before mocking the presenter, joking: "You're all over the place! This is the hardest job in the world."
It is not the first time Carell has taken over presenting duties on the show - in 2010, he gave viewers a muddled forecast, mistaking Europe for America.
