Weather Briefing

VFR

Aurora Municipal Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 9,500 feet and 9 SM visibility.

Wind Analysis

Winds are from the west-northwest (290°) at 6 knots. Runway 27 is favored with a 6-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 9 SM. The ceiling is 5500 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 10°C (50°F) with a dewpoint of 8°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.
