Weather Briefing

VFR

Gary Chicago International Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the south-southwest (210°) at 25 knots with gusts to 32 knots. Runway 20 is favored with a 25-knot headwind and 4-knot crosswind component (gusting to 6 knots crosswind). These are strong winds that may exceed crosswind limits for light aircraft.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 10°C, indicating relatively dry conditions.

Forecast Outlook

The TAF forecast covers the next 24 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 Thunderstorm Rain, Mist. Winds are forecast to reach up to 25 knots during the period. Expect variable wind speeds ranging from 6 to 25 knots. Temporary MVFR conditions are forecast with Light Thunderstorm Rain between 20:00Z and 23:00Z. Temporary IFR conditions are forecast with Mist between 10:00Z and 14:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. Gusty conditions may exceed demonstrated crosswind components for many general aviation aircraft. Check your aircraft's limitations. 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.
