Weather Briefing

MVFR

Lethem Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 10,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west-northwest (290°) at 12 knots. Runway 25 is favored with a 9-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2200 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 23°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.
