Larinioides sclopetarius
(Bridge Orb-weaver)

Furrow Orbweaver was a closer guess. Larinioides cornutus. It could be the answer, but she looks more like a Bridge Orbweaver to me. She looks like she already made her egg sac, which is odd for Springtime. The females often go to the ground after they make egg sacs. Probably because they are dehydrated and weakened. Brown Widows are Southern spiders unless they hitch a ride. You’re more likely to find a Black Widow in New York. They aren’t common in NY but they are there.
