Weather and Water is a 2005 studio album by the Austin, Texas progressive bluegrass band The Greencards.
 Their second Dualtone album release of 2005, after their debut 2003 album "Movin' On" was re-released earlier in the year by their label Dualtone Records, "Weather and Water" was released on June 28.
 In a review of "Weather and Water" in "The Washington Post", it was noted that on this album, unlike their debut, the focus was on the music supporting lyrics, rather than the blues virtuosity of "Movin' On".
 In another review, Jim Abbott of the "Tribune News Service" described The Greencards as polished, "earthy, charming roots music with a sophisticated sheen", but noted that some bluegrass purists may miss the vocal idiosyncrasies that can be found on other bluegrass bands such as the Del McCoury Band.
 All three members of the band sing on "Weather and Water", but Young's voice was noted for its "dreamy, haunting quality".
 Their music through the "Weather and Water" album had been called Celtic-influenced and bluegrass-flavored, but noted that the band had a distinctly American sound despite their overseas origins.
