The palps look pretty big, so is this an adult male?

Yes
but don't forget subadult (or penultimate) males have large, bulbous palps as well.

 
Do these widows overwinter as adults?
It seems early in the year for one to have grown so fast.

 
Very
likely. I believe many spider species overwinter as subadults and immatures, and a few species as adults.
