What is the ceiling and visibility forecast for HOU at 0600Z on the 7th day of the month?

The correct answer indicates that, at 0600Z on the 7th day of the month, the forecast for Houston (HOU) shows 4 nautical miles of visibility paired with an overcast ceiling at 700 feet MSL (Mean Sea Level). This scenario suggests that the visibility is relatively good, which means pilots and air traffic can operate with a lower risk of visual obstructions.

Having an overcast ceiling at 700 feet MSL indicates that clouds cover the sky effectively, which can lead to limited vertical visibility. However, since the visibility is at 4 nautical miles, this is still manageable for many aviation operations, as it provides a reasonable distance for pilots to navigate.

This forecast compares directly with the other choices, which either introduce lower visibility values or varying cloud conditions that can significantly impact flight operations. For instance, a forecast of 2 nautical miles visibility would be more restrictive and could hinder operations. An overcast ceiling at 1500 feet MSL might imply better vertical visibility compared to 700 feet, yet the visibility being lower at 2 nautical miles makes it less favorable. Lastly, 6 nautical miles visibility with broken clouds at 1800 feet MSL represents a better visibility scenario, but the cloud conditions
