Either the battery has a dead cell or something is on drawing power from the battery. Disconnect the negative cable and let it sit overnight. If the battery goes dead, replace it as it has a dead cell. If the battery stays charged then look for something pulling power from the battery. Dome, under-hood, trunk, curtorsey light, etc. Can also be a relay sticking.
A storm has nothing to do with the battery going dead.
