Weather Briefing

VFR

Meiringen Air Base is currently reporting visual flight rules (VFR) conditions with few clouds at 4,000 feet.

Wind Analysis

Winds are from the west (260°) at 5 knots. Runway 28 is favored with a 5-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

No ceiling exists. Cloud layers reported: few at 4,000 ft.

Temperature & Moisture

Temperature is 30°C (86°F) with a dewpoint of 19°C, indicating relatively dry conditions.

Forecast Outlook

The TAF forecast covers the next 29 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: Showers Rain, Thunderstorm Rain, Heavy Thunderstorm Rain. Temporary VFR conditions are forecast with Showers Rain between 11:00Z and 18:00Z. There is a 40% probability of MVFR conditions with Thunderstorm Rain between 11:00Z and 18:00Z. There is a 30% probability of IFR conditions with Heavy Thunderstorm Rain between 11:00Z and 17:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
