Weather Briefing

VFR

St. Anthony Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 3,700 feet.

Wind Analysis

Winds are from the northeast (40°) at 19 knots with gusts to 26 knots. Runway 10/28 is favored with a 10-knot headwind and 16-knot crosswind component (gusting to 23 knots crosswind). Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

The ceiling is 3700 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is -6°C (21°F) with a dewpoint of -8°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely. Temperatures are at or below freezing. Check for icing conditions and ensure aircraft anti-ice/de-ice systems are operational if required.

Forecast Outlook

The TAF forecast covers the next 10 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: Light Freezing Rain, Light Ice Pellets, Mist, Light Snow, Light PLSN, Light Freezing Rain, Mist, Light PLSN, Light Freezing Rain, Mist, FCST, FCST. Temporary IFR conditions are forecast with Light Snow between 22:00Z and 00:00Z. Temporary IFR conditions are forecast with Light Snow between 00:00Z and 05:00Z. Temporary MVFR conditions are forecast with Light PLSN, Light Freezing Rain, Mist, FCST, FCST between 05:00Z and 08:00Z.

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.
