Johnny Downpour was a weatherman for Channel 7 News in Dimmsdale. He replaced Stormy Raynes, but was fired after he got chased off by the angry mob.
This weatherman briefly appeared in the episode Mother Nature, but had no significant role other than being chased by an angry mob.
He replaced recently fired Stormy Raynes, but much like his predecessor he predicted the weather wrong once and was quickly chased out of Dimmsdale by an angry mob. He is never seen again. (He nervously predicted sunny, but it was snowing)
His name is sort of a play on former KABC-TV weather meteorologist, Johnny Mountain.
