Weather Briefing

IFR

Alpena County Regional Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 500 feet and 6 SM visibility.

Wind Analysis

Winds are from the west (280°) at 5 knots. Runway 25 is favored with a 4-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 6 SM. The ceiling is 500 feet AGL (overcast). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 19°C (66°F) with a dewpoint of 18°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. Expected weather includes: Mist, Light Showers Rain, Mist.

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. 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.
