I saw the prior poser from Columbus commenting on WWVA disappearing at sunset.
I have been on I-70 between Zanesville and Cambridge and completely lost them too.
Their pattern appears to be highly directional, north by northeast.
I know ... I read these reports from Cincinnati and other places west of Columbus where people hear WWVA and wonder how. When it goes, it goes completely. That said, maybe where you are near Pittsburgh is in WWVA's cancellation zone so they're weaker there.
