Weather Briefing

MVFR

Burlington International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 6,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the north (360°) at 7 knots. Runway 01/19 is favored with a 7-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 2900 feet AGL (broken), placing conditions in the MVFR category.

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: Light Rain, Mist, Mist. Temporary IFR conditions are forecast with Mist between 08:00Z and 12:00Z.

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. 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.
