Weather Briefing

VFR

Frederick Douglass Greater Rochester International Airport is currently reporting visual flight rules (VFR) conditions with few clouds at 11,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the west-southwest (250°) at 5 knots. Runway 25 is favored with a 5-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: few at 11,000 ft.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 21°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 22 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Thunderstorm Rain, Light Showers Rain. Temporary MVFR conditions are forecast with Thunderstorm Rain between 08:00Z and 10:00Z. There is a 30% probability of VFR conditions with Light Showers Rain between 13:00Z and 17:00Z. There is a 30% probability of MVFR conditions with Thunderstorm Rain between 17:00Z and 19:00Z.

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.
