Weather Briefing
LIFRBirmann 21 Helipad is currently reporting low IFR (LIFR) conditions with overcast skies at 400 feet and 3 km visibility.
Wind Analysis
Winds are from the southeast (140°) at 6 knots. Runway 23/32 is favored with a 0-knot headwind and 6-knot crosswind component.
Visibility & Ceiling
Visibility is reduced to 3 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is very low at 400 feet AGL (overcast), well below circling minimums at most airports.
Temperature & Moisture
Temperature is 12°C (54°F) with a dewpoint of 12°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 12 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Mist. Temporary IFR conditions are forecast with Mist between 00:00Z and 07:00Z. There is a 30% probability of LIFR conditions with Mist between 08:00Z and 11:00Z.
Pilot Recommendations
Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.
