Weather Briefing

VFR

Westchester County Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 3,300 feet and 10 SM visibility.

Wind Analysis

Winds are from the southeast (140°) at 10 knots. Runway 16/34 is favored with a 9-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 3300 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 7°C (45°F) with a dewpoint of 4°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. 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, Mist. Temporary MVFR conditions are forecast between 12:00Z and 13:00Z. Temporary IFR conditions are forecast with Mist between 16:00Z and 19:00Z.

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.

About Westchester County Airport

Overview

Westchester County Airport serves the greater New York metropolitan area, located in White Plains, NY. As a medium-sized airport situated at 439 feet above mean sea level, it provides critical general aviation and regional commercial services. Its strategic location and dual runway configuration make it an important transportation hub for Westchester County and surrounding regions.

Flying Conditions

Weather conditions at KHPN are predominantly VFR, with 84.4% of observations reporting visual flight rules. 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.

Approach Considerations

November, September, and December represent the most consistently favorable VFR months for operations. With an average visibility of 9.4 statute miles and only 3.2% of observations reporting fog, approaches are generally straightforward. Pilots should be prepared for potential reduced visibility conditions, which occur in approximately 2.3% of observations with visibility below 3 statute miles.
