You have a chance of getting any station within about 60-70 miles of you. That's the point you become over-the-horizon from the transmitter. In some cases, it's possible the station will need to be transmitting with more power than they currently are, so you may not receive them right now, but eventually.
I'd say it's probably impractical to think you're going to get Philadelphia stations with any regularity... only when tropospheric conditions are favorable.
Try the link below my signature.
Trenton, NJ; Poughkeepsie, NY; Smithtown, NY; Bridgeport, CT are likely
Allentown, PA; New Haven, CT;Phialdelphia, PA are probably very intermittent if at all
