Yahz- Unfortunately, you are out of luck. All of Northern and Central DE, Southeast PA, and Southern NJ is fed out of Philly. Verizon only set up 1 Weather Channel system at each VHO.
So, in Dover you see the weather for Philly, in Wilmington, you see it for Philly, etc. There is no use sitting on hold. VZ's answer was to simply use the widgets application to get more local information.
Really a downside to FIOS TV if you're into weather.
There is a place where you can help from verizon techs online here;
You will have to join the site but others in the forums have said they have been helped there.
