Weather Briefing

IFR

Cape Cod Coast Guard Air Station is currently reporting instrument flight rules (IFR) conditions with overcast skies at 700 feet and 10 SM visibility.

Wind Analysis

Winds are from the north (10°) at 10 knots. Runway 05/23 is favored with a 8-knot headwind and 6-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 700 feet AGL (overcast). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 9°C (48°F) with a dewpoint of 7°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. 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.
