Weather Briefing

VFR

Frederick Douglass Greater Rochester International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 12,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the southwest (220°) at 7 knots. Runway 22 is favored with a 7-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 12000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 20°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 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers Rain, Light Thunderstorm Rain. Temporary MVFR conditions are forecast with Light Showers Rain between 08:00Z and 10:00Z. There is a 30% probability of IFR conditions with Light Thunderstorm Rain between 14:00Z and 18:00Z. There is a 30% probability of MVFR conditions with Light Thunderstorm Rain between 18:00Z and 20:00Z.

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.
