Visibility & Ceiling
Visibility is 8 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 22°C (72°F) with a dewpoint of 21°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. 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: Mist, Thunderstorm Rain, Mist. Temporary LIFR conditions are forecast with Mist between 10:00Z and 12:00Z. There is a 30% probability of MVFR conditions with Thunderstorm Rain, Mist between 18:00Z 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.
