Weather Briefing

VFR

Ann Arbor Municipal Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 4,300 feet and 10 SM visibility. Note: This observation is 1 hours old and conditions may have changed.

Winds are from the northwest (310°) at 3 knots.

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: few at 4,300 ft.

Temperature & Moisture

Temperature is 7°C (45°F) with a dewpoint of 4°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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.

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