I don't know what it is, but it looks like something in the Oncidium/Odontoglossum group. This is a good resource for looking up orchid flower photos, but it is much easier to use if you know the name of what you are looking for:
I went to IOSPE and poked around a little. Look up genus Rhynchostele, a genus from Mexico that has been known as Odontoglossum, Oncidium and Lemboglossum, among others. Some species are native very close to you.
