The featured chart displays a forecast model's initial analysis along with the latest forecast of precipitable water approximately for Ames. This value can be considered the depth of water in the atmosphere if all of it was squeezed out. When values exceed two inches, slow moving thunderstorms are able to quickly dump lots of rain. The heaviest rains this morning are just north of Ames with a report of 5 inches already around Fort Dodge.
