Weather Briefing
IFRSt. Louis Lambert International Airport is currently reporting instrument flight rules (IFR) conditions with broken clouds at 11,000 feet and 2.043 km visibility.
Wind Analysis
Winds are from the west-southwest (240°) at 18 knots with gusts to 31 knots. Runway 24 is favored with a 18-knot headwind and 0-knot crosswind component. Student pilots and low-time aviators should exercise caution.
Visibility & Ceiling
Visibility is reduced to 2.043 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is 11000 feet AGL (broken), well above standard VFR minimums. Caution: cumulonimbus (thunderstorm) clouds reported at 5,500 ft AGL, indicating convective activity in the area.
Temperature & Moisture
Temperature is 23°C (73°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 26 hours. Conditions are expected to remain VFR throughout the forecast period. Expected weather includes: Light Showers Rain.
Pilot Recommendations
An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. Gusty conditions may exceed demonstrated crosswind components for many general aviation aircraft. Check your aircraft's limitations. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About St. Louis Lambert International Airport
Overview
St. Louis Lambert International Airport serves as a major commercial airport located in the metropolitan area of St. Louis, Missouri. Situated at an elevation of 618 feet mean sea level, the airport is a critical transportation hub for the region. Its four substantial concrete runways demonstrate substantial capacity for commercial and general aviation operations.
Flying Conditions
The airport's four runways ranging from 7,600 to 11,020 feet provide flexibility for diverse aircraft types across varying weather conditions. Located at coordinates 38.748697, -90.370003, the airport experiences typical Midwestern weather patterns with potential seasonal wind variations. Pilots should anticipate potential crosswind scenarios given the multiple runway orientations.
Notable Features
St. Louis Lambert International features four parallel and perpendicular runway configurations, offering multiple approach and departure options. The longest runway (12R/30L) extends 11,020 feet, accommodating large commercial aircraft and providing significant operational flexibility. The airport's diverse runway layout enables efficient air traffic management across different wind conditions.
Approach Considerations
Runway selection will depend on prevailing wind direction, with options spanning 06/24, 11/29, 12L/30R, and 12R/30L. The substantial runway lengths provide considerable margins for various aircraft performance envelopes. Pilots should carefully assess current meteorological conditions and wind vectors when planning approaches to maximize safety and operational efficiency.
