Weather Briefing
VFRChanute Martin Johnson Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 4,400 feet and 10 SM visibility.
Wind Analysis
Winds are from the south (190°) at 17 knots with gusts to 30 knots. Runway 18/36 is favored with a 17-knot headwind and 3-knot crosswind component (gusting to 5 knots crosswind). Student pilots and low-time aviators should exercise caution.
Visibility & Ceiling
Visibility is 10 SM. No ceiling exists. Cloud layers reported: scattered at 4,400 ft, scattered at 5,000 ft.
Temperature & Moisture
Temperature is 31°C (88°F) with a dewpoint of 22°C, indicating moderate moisture conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.
Forecast Outlook
The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period. Winds are forecast to reach up to 20 knots during the period.
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.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Chanute Martin Johnson Airport
Overview
Chanute Martin Johnson Airport serves the Chanute, Kansas region as a medium-sized airport situated at 1002 feet above mean sea level. Located at coordinates 37.668173, -95.486727, the airport provides critical aviation infrastructure for southeastern Kansas, supporting local and regional transportation needs.
Flying Conditions
Weather conditions at KCNU demonstrate predominantly favorable VFR flying conditions, with 75.5% of observations reporting visual flight rules. Temperatures range dramatically from -16°C to 32°C, with an average of 10.6°C, requiring pilots to be prepared for significant temperature variations. Wind patterns are consistently from the south at an average of 8 knots, with occasional peaks up to 31 knots.
Notable Features
The airport features two runways: a 2200-foot grass runway (08/26) and a 4255-foot asphalt runway (18/36). Both runways demonstrate 100% favorable wind alignment, with relatively modest average crosswind conditions of 6.3 knots for the grass runway and 3.7 knots for the asphalt runway. Visibility averages 9.1 statute miles, with only 2.4% of observations showing visibility below 3 miles.
Approach Considerations
Pilots should note January, September, and October offer the most consistent VFR conditions for operations. With low occurrence of IFR (6.1%) and LIFR (6.6%) conditions, the airport generally provides reliable access. The southerly prevailing winds and low average crosswinds make both runways consistently accessible, with minimal wind-related approach challenges.
