Long Beach, CA occasionally will have the approach end of 30 and all of 25L socked in at zero visibility in fog off the ocean to the south, including the tower, and the field/ATIS is officially IFR. The north runway is clear, and visibility is 20 miles, CAVU.

One can come and go in the class D under Special VFR, when flight conditions are much BETTER than Special VFR minima, but the official WX is WOXOF.
