Weather Briefing

VFR

Roberts International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 1,400 feet and 10 miles or greater visibility.

Wind Analysis

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

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 1,400 ft, few at 2,300 ft (CB). Caution: cumulonimbus (thunderstorm) clouds reported at 2,300 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 26°C (79°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Thunderstorm Rain. Temporary LIFR conditions are forecast with Light Thunderstorm Rain between 23:00Z and 02:00Z.

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.
