Sweet Potato harvest question.

So I'm at roughly day 120 on my sweet potato vines. In zone 5b. Weather is getting colder but the leaves are still staying green. Any harm in leaving them in the ground for another week? Lowest temp will be mid-40's at night and 60's to 70's during the day. Will they grow larger?
