Weather Briefing

VFR

Bomar Field / Shelbyville Municipal Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the north (360°) at 11 knots. Runway 36 is favored with a 11-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 11°C (52°F) with a dewpoint of 8°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.
