What are the current weather conditions for Chicago Midway Airport (KMDW)?

The correct choice indicates that the sky is overcast at 700 feet with visibility of 1-1/2 statute miles and rain. This reflects a situation where the cloud base is low, which could impact flight operations, particularly for pilots who rely on visual flight rules (VFR). The specified visibility is below 2 statute miles, which may necessitate instrument flight rules (IFR) if further operations are required, given the presence of rain.

As pilots must be keenly aware of current weather conditions for safety and compliance with regulations, the detail about both the low cloud ceiling and reduced visibility in this choice is crucial. Flight operations in such conditions generally require caution and adherence to IFR, depending on the visibility and cloud clearance requirements.

In contrast, the other options describe either higher ceilings or better visibility, which do not align with the implications of being in low visibility conditions. Therefore, they wouldn't accurately reflect the necessary decision-making that a pilot would need to undertake when considering the flight operations at Chicago Midway Airport under such adverse weather.
