Wind Analysis

Winds are from the west (280°) at 8 knots. Runway 28 is favored with a 8-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is 9 SM. The ceiling is 5000 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 7°C (45°F) with a dewpoint of 5°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, Light Showers Rain, Mist, Light Rain, Mist, Light Showers Rain, FCST, FCST. Winds are forecast to reach up to 25 knots during the period. Expect variable wind speeds ranging from 8 to 25 knots. Temporary VFR conditions are forecast with Light Showers Rain between 13:00Z and 15:00Z. Temporary MVFR conditions are forecast with Light Showers Rain, Mist between 15:00Z and 17:00Z. Temporary IFR conditions are forecast with Light Rain, Mist between 17:00Z and 22:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
