Weather Briefing

MVFR

Bozeman Yellowstone International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,400 feet and 7 SM visibility.

Wind Analysis

Winds are from the east (80°) at 6 knots. Runway 11/29 is favored with a 5-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 7 SM. The ceiling is 1400 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 2°C (36°F) with a dewpoint of 2°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 30 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Rain, Mist, Light RASN, Light Snow, Light Showers Snow, Light Snow, Mist. Expect variable wind speeds ranging from 3 to 15 knots. There is a 30% probability of MVFR conditions with Light Snow between 14:00Z and 19:00Z.

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 Bozeman Yellowstone International Airport

Overview

Bozeman Yellowstone International Airport serves the growing Montana region, situated at 4,473 feet mean sea level near Bozeman. The airport features three runways, with the primary 12/30 runway extending 9,003 feet, capable of accommodating a wide range of aircraft operations. Its international designation reflects the airport's strategic location near popular national parks and recreational areas.

Flying Conditions

Statistical data reveals predominantly favorable flying conditions, with 87.8% of observations reporting VFR conditions. Wind patterns are consistent from the southeast at an average of 6.7 knots, with occasional gusts up to 40 knots. Temperature ranges from -23°C to 28°C, presenting potential temperature-related performance considerations for aircraft operations.

Notable Features

The airport's high elevation at 4,473 feet MSL requires careful performance planning, particularly during warmer months. All three runways demonstrate 100% favorable wind alignment, with consistently low average crosswind components around 4-4.7 knots. The terrain surrounding Bozeman presents complex mountainous geography that can influence local weather patterns and wind behaviors.

Approach Considerations

Pilots should anticipate generally stable approach conditions, with good average visibility at 9.6 statute miles. Seasonal variations are minimal, with January, September, and October presenting the most consistent VFR conditions. The multiple runway configuration offers flexibility in wind and approach management, with minimal crosswind limitations based on the provided statistical analysis.
