Weather Briefing

IFR

Frederick Douglass Greater Rochester International Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 2,400 feet and 10 SM visibility. Note: This observation is 1.1 hours old and conditions may have changed.

Wind Analysis

Winds are from the north-northwest (340°) at 5 knots. Runway 04/22 is favored with a 3-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 700 feet AGL (broken). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 7°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 20 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 Drizzle, Light Rain, Mist. Temporary IFR conditions are forecast with Light Rain, Mist between 22:00Z and 23:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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.
