Weather Briefing

VFR

Nan Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 3,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north (360°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 3,000 ft.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 26°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 24 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: Rain, Thunderstorm Rain. Temporary IFR conditions are forecast with Rain between 00:00Z and 06:00Z. Temporary IFR conditions are forecast with Thunderstorm Rain between 09:00Z and 17:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
