Weather Briefing

VFR

Olympia Regional Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 7,000 feet and 6 SM visibility.

Wind Analysis

Winds are from the south (190°) at 9 knots. Runway 17/35 is favored with a 8-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 6 SM. The ceiling is 3400 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 9°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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 Showers Rain, Light Rain, Mist.

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.
