The forecasted visibility for KMEM between 1000Z and 1200Z is 3 statute miles. This indicates that during this time period, conditions are expected to allow pilots to see a distance of three miles, which is generally considered good visibility for flying.

Visibility is a crucial factor in aviation, as it affects a pilot's ability to navigate and maintain visual separation from other aircraft and obstacles. When visibility is forecasted to be 3 statute miles, it provides adequate conditions for visual flight rules (VFR) operations.

In this scenario, the alternative options of less than 3 statute miles, like 1/2 statute mile, would imply significantly poorer visibility and could indicate weather conditions that are not ideal for flying. On the contrary, a forecast of 6 statute miles suggests excellent visibility, which would not align with the prediction for this timeframe.

Therefore, the selected forecast of 3 statute miles accurately reflects a typical mid-range visibility that would be suitable for most flight operations.
