Weather Briefing

VFR

Jamestown Regional Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the south (170°) at 12 knots. Runway 13/31 is favored with a 9-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 16°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Thunderstorm Rain, Light Rain. Winds are forecast to reach up to 20 knots during the period. Expect variable wind speeds ranging from 8 to 20 knots. There is a 30% probability of VFR conditions with Light Rain between 12:00Z and 16:00Z. There is a 30% probability of VFR conditions with Light Rain between 16:00Z and 20:00Z.

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.
