The quick answer as to why WJLB is overpowering WGRD in some areas is that occassionally humidity and some other factors eff with FM waves and TV signals. It's really bad around water. Sometimes, you can't hear the station we're on in New Jersey even when you're standing a mile from the tower.
If you really want to learn more about "Tropospheric Scattering" and "Tropospheric Propagation", have at it:

Also, most AM stations are required to LOWER their power at night. I don't know of any that are allowed to increase power.
Here's some more nerd-speak about that, if you're interested.
