I think this may be a nursery web spider?
Yes! https://bugguide.net/index.php?q=search&keys=pisaurina+mira&search=Search This is an odd time to find one outdoors. It may be immature enough to still have the ability to survive freezing temperatures.
It was a bit cold, high 20’s last night. But it was 57 yesterday morning.
Wow! When did Delaware become a tropical paradise? 😉 There was a Nursery Web Spider that lived on the siding of my house. She went under it, into the insulation sometimes.
