Narrative:
After cleared for takeoff runway 3L, tower reported visibility 700-0- 0. We decided to continue since abort at 100 KTS not feasible. Visibility was 700-1200-700 last reported before roll. Just prior to takeoff, visibility was reported as 700 ft. The tower should have given us all 3 readings.
