The Weather Girls are an American female duo whose best-known line-up comprised Martha Wash and Izora Armstead. Formed in 1976 in San Francisco, California, The Weather Girls members began their musical career as Two Tons O' Fun, the female backup duo for disco singer Sylvester. After years of limited success singing background for Sylvester, the duo were signed in 1979 to Fantasy Records. The Weather Girls was launched into mainstream recognition following the release of their best-selling single, "It's Raining Men" (1982), which became their first number-one Dance song. Despite critical and commercial success, the duo struggled to repeat the success of "It's Raining Men" and ultimately disbanded after the release of their self-titled fifth album The Weather Girls in 1988.
