Weather Briefing

VFR

Chicago Midway International Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 25,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the northwest (320°) at 6 knots. Runway 31 is favored with a 6-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 17000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 21°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 30 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Rain, Mist, Thunderstorm Rain, Mist, Mist. Temporary VFR conditions are forecast with Light Rain, Mist between 06:00Z and 07:00Z. Temporary IFR conditions are forecast with Thunderstorm Rain, Mist between 20:00Z and 00:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Chicago Midway International Airport

Overview

Chicago Midway International Airport serves as a major commercial airport located in Chicago, Illinois. Situated at an elevation of 620 feet MSL, it handles significant passenger and cargo traffic for the Chicago metropolitan area. The airport's strategic location and multiple runways make it a critical transportation hub in the Midwest region.

Flying Conditions

The airport's five runways provide operational flexibility across different wind conditions, with lengths ranging from 3,859 to 6,522 feet. Runway surfaces include asphalt (ASP), portland cement (PEM), and concrete (CON) compositions, which can influence landing and takeoff characteristics. Pilots should anticipate variable wind conditions typical of the Great Lakes region, particularly during seasonal transitions.

Notable Features

Midway features five runways with diverse orientations (04/22, 13/31), allowing for multiple approach and departure options based on wind direction. The airport's relatively modest elevation of 620 feet MSL provides consistent atmospheric conditions without significant altitude-related performance challenges. Its urban location means pilots must be prepared for complex airspace interactions and potential air traffic density.

Approach Considerations

Runway selection will depend primarily on prevailing wind conditions, with multiple options available due to the five-runway configuration. The longest runway (13C/31C at 6,522 feet) provides the most substantial landing and takeoff capabilities. Pilots should carefully review current wind data and air traffic instructions when planning approaches to this multi-runway airport.
