Weather Briefing
MVFRPurdue University Airport is currently reporting marginal VFR (MVFR) conditions with few clouds at 700 feet and 5 SM visibility.
Wind Analysis
Winds are calm, presenting no crosswind concerns for any runway.
Visibility & Ceiling
Visibility is 5 SM. No ceiling exists. Cloud layers reported: few at 700 ft.
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 22 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: Mist, Light Thunderstorm Rain. There is a 30% probability of MVFR conditions with Light Thunderstorm Rain between 18:00Z and 22:00Z.
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.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Purdue University Airport
Overview
Purdue University Airport serves the Lafayette, Indiana region as a medium-sized airport associated with Purdue University. Located at 40.412875, -86.939363 with an elevation of 606 feet MSL, the airport provides critical aviation infrastructure for academic, training, and general aviation purposes. The airport features two asphalt runways capable of supporting a variety of aircraft operations.
Flying Conditions
Weather conditions at KLAF demonstrate significant variability, with Visual Flight Rules (VFR) predominating at 64.4% of observations. Pilots can expect westerly winds averaging 7.9 knots, with occasional stronger gusts up to 28 knots. Temperature ranges from -22°C to 31°C, indicating potential challenging winter and summer conditions that require appropriate preflight planning and aircraft preparation.
Notable Features
Both runways offer favorable wind alignment, with 100% wind compatibility and minimal average crosswind components. Runway 05/23 measures 4,226 feet, while Runway 10/28 provides a longer 6,600-foot surface, offering flexibility for different aircraft types and operational requirements. Visibility typically remains excellent, averaging 8.9 statute miles with only 3% of observations showing reduced visibility.
Approach Considerations
Seasonal considerations suggest September, October, and January offer the most consistent VFR conditions for pilots. With calm wind conditions present 21% of the time, pilots should be prepared for potential wind variability. The airport's two runway configuration allows for optimal wind-aligned approaches, with Runway 10/28 providing the longest surface for more demanding aircraft operations.
