Weather Briefing
MVFRNan Airport is currently reporting marginal VFR (MVFR) conditions with clear skies and 8 km visibility. Note: This observation is 4.1 hours old and conditions may have changed.
Wind Analysis
Winds are from the south (170°) at 5 knots. Runway 20 is favored with a 4-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is 8 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 34°C (93°F) with a dewpoint of 21°C, indicating relatively dry 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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Thunderstorm Rain, Mist. Temporary IFR conditions are forecast with Thunderstorm Rain between 12:00Z and 16:00Z.
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 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.
