Under what visibility conditions would moderate snow not be reported when other phenomena are present?

Moderate snow is reported in accordance with visibility criteria; however, if visibility is at or below 3/4 statute miles and other significant weather phenomena are present, moderate snow may not be indicated. In this context, when visibility is 3/4SM, it typically means that the snow could be heavy enough that it significantly reduces visibility, but not to such an extent that it requires reporting as moderate snow.

The reporting criteria consider both the intensity of the snowfall and the visibility resulting from it. Because of this interplay, when other weather phenomena are present alongside moderate snow, and visibility exceeds certain thresholds, the snowfall may not be reported in the same manner. The visibility must be substantially impaired to warrant reporting, and if it is somewhat compromised but still assessable, like at 3/4SM, reporting might omit more detailed descriptions of snow intensity.

Therefore, in cases where visibility is at 3/4SM, it indicates that while there may be snowfall, the conditions may not meet the threshold for explicitly stating moderate snow in conjunction with other weather phenomena.
