Weather Briefing
MVFRChanute Martin Johnson Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,300 feet and 10 SM visibility.
Wind Analysis
Winds are from the south-southwest (200°) at 9 knots. Runway 18/36 is favored with a 8-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1300 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 16°C (61°F) with a dewpoint of 13°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
Forecast Outlook
The TAF forecast covers the next 24 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended.
Pilot Recommendations
VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.

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.
