Weather Briefing

MVFR

Frederick Douglass Greater Rochester International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,100 feet and 10 SM visibility.

Wind Analysis

Winds are from the variable directions at 3 knots.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 1100 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 24°C (75°F) with a dewpoint of 22°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: Light Showers Rain, Mist. Temporary MVFR conditions are forecast with Light Showers Rain between 20:00Z and 22:00Z. There is a 30% probability of VFR conditions with Light Showers Rain between 22:00Z and 01:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.
