Weather Briefing
MVFRLa Grande-4 Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,200 feet and 9 SM visibility.
Wind Analysis
Winds are from the southwest (230°) at 5 knots. Runway 27 is favored with a 4-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is 9 SM. The ceiling is 2200 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is -19°C (-2°F) with a dewpoint of -22°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods. Temperatures are at or below freezing. Check for icing conditions and ensure aircraft anti-ice/de-ice systems are operational if required.
Forecast Outlook
The TAF forecast covers the next 10 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Snow, FCST, FCST. Temporary MVFR conditions are forecast with Light Snow between 11:00Z and 18:00Z.
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 La Grande-4 Airport
Overview
La Grande-4 Airport serves the remote region of northern Quebec, situated at an elevation of 1005 ft MSL. Located at coordinates 53.754700, -73.675301, this medium-sized airport provides critical transportation infrastructure in a challenging northern environment. The airport's single gravel runway supports essential regional and resource-sector air operations.
Flying Conditions
Pilots should anticipate variable weather conditions, with marginal VFR (MVFR) dominating 53.7% of observations. Temperature ranges dramatically from -33°C to 23°C, with an average of -7.2°C, presenting significant potential for icing and temperature-related performance considerations. Wind is predominantly southwest at 9.1 knots, with occasional gusts up to 26 knots and calm periods occurring 4.8% of the time.
Notable Features
The 5000-foot gravel runway (09/27) presents unique operational challenges typical of northern Canadian airports. Gravel surface requires heightened awareness of potential foreign object damage (FOD) and modified landing/takeoff techniques. The airport's geographical position suggests potential terrain complexity and rapid weather changes characteristic of northern Quebec's landscape.
Approach Considerations
Runway 09/27 demonstrates 100% favorable wind alignment, with an average crosswind of only 4.8 knots. Pilots should note best VFR months are October, January, and September, with visibility averaging 7.1 statute miles. During approach, be prepared for potential reduced visibility, with 5.6% of observations showing visibility below 3 statute miles.
