Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 5000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 15°C (59°F) with a dewpoint of 14°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. 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 Rain, Light Rain, Mist, Light Showers Rain, Mist. Temporary IFR conditions are forecast with Light Rain, Mist between 17:00Z and 21:00Z.
