Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: few at 3,000 ft.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 11°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: Mist.

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.

Pilots can expect westerly winds averaging 8.3 knots, with occasional stronger gusts up to 28 knots. Temperature variations are significant, ranging from -12°C to 29°C, which can impact aircraft performance and fuel considerations.

Notable Features

The airport features two asphalt runways: Runway 11/29 at 4,451 feet and Runway 16/34 at 6,548 feet. Both runways demonstrate 100% favorable wind alignment, with modest average crosswind components of 3.8 and 5.2 knots respectively. The geographical coordinates (41.067001, -73.707603) position the airport in a relatively flat terrain characteristic of the New York metropolitan region.
