Visibility & Ceiling
Visibility is 6 SM. No ceiling exists. Cloud layers reported: few at 4,000 ft.
Temperature & Moisture
Temperature is 25°C (77°F) with a dewpoint of 25°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 24 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: Thunderstorm Rain, Mist. Temporary IFR conditions are forecast with Thunderstorm Rain, Mist between 03:00Z and 06:00Z. There is a 30% probability of IFR conditions with Thunderstorm Rain, Mist between 21:00Z and 00:00Z.
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.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
