Meteorite on a collision course with earth-- how to NOT see it coming?

What are some reasonably-realistic scientific scenarios in which, assuming all the current technology we have at the moment was in working order, scientists might miss seeing a potentially catastrophic meteorite on a collision course with Earth until it was actually entering the atmosphere? I assume that astrophysicists see potentially threatening asteroids/meteors coming months, if not years, in advance. But could there be a circumstance in which that might not be the case? Thanks!
