Weather Briefing

MVFR

Stillwater Regional Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,500 feet and 10 SM visibility.

Wind Analysis

Winds are from the south (180°) at 11 knots. Runway 17/35 is favored with a 11-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 1500 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 19°C (66°F) with a dewpoint of 15°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Temporary IFR conditions are forecast between 18:00Z and 20:00Z.

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 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.
