Weather Briefing

IFR

Stillwater Regional Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 600 feet and 10 SM visibility.

Wind Analysis

Winds are from the south (180°) at 12 knots. Runway 17/35 is favored with a 12-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 600 feet AGL (overcast). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 14°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. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
