These graphics show the last freeze in the spring (above) and the first freeze in the Autumn.

You can see that the growing season in McKean County lasts from May 21st through October 1st, while the growing season in Lancaster County runs from April 11th through November 1st.  Therefore, crops can generally grow for two months longer in Lancaster, PA versus in Bradford, PA.

Between these dates (in the warm-season), your National Weather Service Office in State College, PA will issue Frost Advisories (minimum temperatures between 33 and 36 degrees) and Freeze Warnings (minimum temperatures of 32 degrees or colder), as necessary.
