Visibility & Ceiling

Visibility is 9 SM. The ceiling is 1300 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 20°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 12 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 Showers Rain, Mist, Light Rain, Light Rain, Mist, Light Rain, FCST, FCST. Temporary MVFR conditions are forecast with Light Showers Rain, Mist between 08:00Z and 10:00Z. Temporary MVFR conditions are forecast with Light Rain between 10:00Z and 12:00Z. There is a 30% probability of IFR conditions with Light Showers Rain, Mist between 10:00Z 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.

About North Bay Jack Garland Airport

Overview

North Bay Jack Garland Airport serves the North Bay region of Ontario, Canada, situated at an elevation of 1215 ft MSL. The airport supports medium-sized aircraft operations with three runways offering substantial operational flexibility, including a primary 10,000 ft asphalt runway capable of handling larger aircraft.

Flying Conditions

Weather conditions at CYYB demonstrate significant variability, with VFR conditions present 44.4% of the time and MVFR conditions occurring 30% of observations. Temperature ranges extensively from -31°C to 27°C, with an average of -2.1°C, indicating potential challenging winter operations and substantial seasonal temperature fluctuations.

Notable Features

The airport features three runways with different surface compositions: two asphalt (08/26 and 18/36) and one grass (13/31). Prevailing winds consistently approach from the northwest at 315° with an average speed of 8.3 knots, providing predictable wind patterns for pilots planning approaches and departures.

Approach Considerations

All three runways demonstrate 100% favorable wind alignment, with relatively consistent average crosswind components between 4.7 and 5.5 knots. Visibility averages 13.7 statute miles, though pilots should be prepared for occasional reduced visibility, with 5.7% of observations showing conditions below 3 statute miles and 3.7% experiencing fog.
