Weather Briefing
MVFRGreat Falls International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,300 feet and 10 SM visibility.
Wind Analysis
Winds are from the northwest (320°) at 19 knots with gusts to 29 knots. Runway 35 is favored with a 16-knot headwind and 10-knot crosswind component (gusting to 15 knots crosswind). Student pilots and low-time aviators should exercise caution.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1300 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 5°C (41°F) with a dewpoint of 4°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 20 hours. Conditions are expected to remain MVFR throughout the forecast period. Expected weather includes: Light Showers Rain, Mist, Light Rain, Light Snow, Mist, Light Snow. Winds are forecast to reach up to 25 knots during the period. There is a 30% probability of MVFR conditions with Light Snow, Mist between 09:00Z and 12:00Z. There is a 30% probability of MVFR conditions with Light Snow, Mist between 15:00Z and 21:00Z.
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 Great Falls International Airport
Overview
Great Falls International Airport serves central Montana as a medium-sized airport located at 3680 feet mean sea level near the city of Great Falls. The airport supports regional and commercial aviation with three asphalt runways, offering substantial landing options for various aircraft types. Its geographic position in north-central Montana provides critical transportation infrastructure for the region.
Flying Conditions
Weather observations indicate predominantly favorable flying conditions, with 85.5% of recorded periods under Visual Flight Rules (VFR). Southwest winds averaging 11.6 knots are typical, with temperatures ranging from -24°C to 31°C. Pilots can expect the most consistent VFR conditions during September, January, and October, with minimal instrument meteorological conditions reported.
Notable Features
The airport's elevation of 3680 feet MSL and substantial runway lengths (primary runway 03/21 at 10,502 feet) accommodate a wide range of aircraft operations. Wind patterns demonstrate consistent favorable runway alignment, with all three runways showing 100% wind compatibility. Crosswind components remain relatively moderate, ranging from 4.6 to 8.5 knots across different runway headings.
Approach Considerations
Runway 03/21 offers the longest and most versatile landing surface, with the most stable wind conditions. Pilots should anticipate southwest prevailing winds and be prepared for potential temperature-related performance considerations given the airport's elevation. The multiple runway configurations provide flexibility for approaches under various wind conditions, with minimal directional restrictions.
