Am I sure it is a Yellow-throated-ish song? Yes. Am I sure that the bird singing it is a Yellow-throated Warbler? Well, not 100%, but I don't really know what else it could be.
If I were to hear it out east I would call it Yellow-throated without a second thought. The song descends gradually, with a short ending that has an upward inflection at the end. At the very least, it's certainly worth getting in contact with your local ebird reviewer and/or posting on local RBA and advanced ID pages, given that Yellow-throated would be quite rare in your area.
