Weather Channel

Last night and this morning, weather channel is broadcasting a blank screen. It is not a signal issue as there is no error messages or no message stating "channel will be available shortly ", just a blank screen. If I keep tuning to channel, after a while it will play some video, but then go to a blank screen again. Lewistown, Pa does not have channel in HD, so I can't check to see if HD version is also out. Channel does not any video on X1 box as well as small DTA in other room.
