What visibility is forecast for KOKC between 0600Z to 0800Z?

The forecast visibility for KOKC between 0600Z and 0800Z is indicated to be greater than 6 statute miles, which reflects typically favorable weather conditions. This prediction suggests that there will be clear air or favorable meteorological conditions allowing visibility to exceed standard thresholds.

When visibility is forecast to be greater than 6 statute miles, it allows for a broader margin of operational safety for pilots, especially during takeoff and landing. Good visibility is crucial for visual flight rules (VFR) operations, and this forecast indicates that pilots can expect a clear line of sight during this period.

In contrast, the other options imply reduced visibility, which would generally be associated with weather phenomena such as fog, rain, or low clouds that can impair a pilot's ability to see other aircraft, navigational aids, or the runway. Since the forecast specifically highlights visibility exceeding 6 miles, it indicates a period of optimal flying conditions for air traffic.
