We found this in the yard in Pittsburgh, PA. ANy ideas as to what it is and what kind of moth/butterfly it will turn into?

Heterocampa Caterpillar

Hi Wendi,
Though your photo doesn’t show the head, this pattern and coloration is characteristic of Prominent Caterpillars in the genus
Heterocampa just prior to pupation.  BugGuide has good images of the caterpillars in the genus Heterocampa as well as images of the adult moths.
