Weather Briefing

MVFR

Grenchen Airfield is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,400 feet and 6 km visibility.

Wind Analysis

Winds are from the variable directions at 3 knots.

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 2400 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 6°C (43°F) with a dewpoint of 6°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 9 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Showers Rain, Thunderstorm Rain. Temporary MVFR conditions are forecast with Showers Rain between 15:00Z and 19:00Z. There is a 40% probability of MVFR conditions with Thunderstorm Rain between 15:00Z and 18:00Z.

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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
