The thing is, many of us on the opposite end of the country
from WWVB have to rely on favorable propagation to make our
clocks work reliably. What happens if noon and midnight
aren't favorable times?

Maybe this is related to the phase modulation time code
protocol used by WWVB since October 29th, 2012.
Their website also states that clocks using information
from the carrier will no longer work, and that during the
transition period (at least March 21st 2013), the PM
signal will be turned for for 30 minutes twice a day
(noon and midnight MST) so maybe check if the clocks
sync then?
