I looked at the weather history on Weather Underground and PVD reported
visibilities in the 0.1 and 0.2 range around midnight that night, below
the standard ILS minimums for PVD. The Cat II and Cat III approaches
(both to ry 5) are not authorized when the tower is not in operation
according to the U.S. Terminal Procedures for PVD.


The FAA spokesman said at least one of the Southwest flights missed an
approach. Did they begin an approach when the observed weather was below
minimums?
