Narrative:

On approach into msp at XA00 local, prior to FAF, approach control told us that the RVR for runway 30R was 4000 ft. ATIS at that time said the visibility was 1 1/2 mi. The approach controller then said that tower might be calling some other visibility, calling into question the RVR value. We continued for the ILS runway 30R because we were 1-2 mi from the FAF and we were assuming that tower was calling the higher value. After we passed the FAF, tower called the visibility below CAT 1 ILS minimums. We continued the approach and went missed.
