Weather Briefing

VFR

Massena International Airport Richards Field is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the east-northeast (60°) at 5 knots. Runway 05/23 is favored with a 5-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

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

Temperature & Moisture

Temperature is 10°C (50°F) with a dewpoint of 7°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 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, Light Showers Rain. Winds are forecast to reach up to 24 knots during the period. Expect variable wind speeds ranging from 4 to 24 knots. There is a 30% probability of MVFR conditions with Light Showers Rain, Mist between 23:00Z and 00:00Z.

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.
