Weather Briefing

MVFR

Westchester County Airport is currently reporting marginal VFR (MVFR) conditions with few clouds at 100 feet and 4 SM visibility.

Wind Analysis

Winds are from the west-southwest (240°) at 5 knots. Runway 29 is favored with a 3-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 4 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: few at 100 ft.

Temperature & Moisture

Temperature is 22°C (72°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 21 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Mist, Thunderstorm Rain. Temporary MVFR conditions are forecast with Mist between 07:00Z and 11:00Z. There is a 30% probability of MVFR conditions with Thunderstorm Rain between 20:00Z and 00:00Z.

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.

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.
