Generations of regional airline pilots have never trusted inland city/town morning CAVOK forecasts in winter when anti-cyclonic conditions exist with dry bulb, wet bulb temperatures within one degree of each other. A call to the forecaster at Mildura Met. Office equips the pilot with additional knowledge when decision making, a line of defence which I expect is not pursued by modern flight ops. departments. As mentioned previously, good airmanship by the crew in a safe outcome. Perhaps unkind judgement here if events happened too quickly for flight ops. to catch up.
