Weather Briefing

MVFR

Olympia Regional Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 3,800 feet and 4 SM visibility.

Wind Analysis

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

Visibility & Ceiling

Visibility is 4 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 3800 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 10°C (50°F) with a dewpoint of 9°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. Temporary IFR conditions are forecast with Mist between 10:00Z and 12:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.
