One of the things I dislike about
WTTR.IN is that it doesn't have any disambiguation. There's one municipality named Chillicothe (the one in #OH; the others don't exist), and the same for every other municipality name. I've started using airport codes instead. There's only one MCI, one ONT, one LAX, one SMF, one DFW, and so on, so it always pulls up the airport you want.
