Weather Briefing

LIFR

Okayama Momotaro Airport is currently reporting low IFR (LIFR) conditions with broken clouds at 400 feet and 3 km visibility.

Wind Analysis

Winds are from the southeast (140°) at 2 knots.

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 (broken), well below circling minimums at most airports.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 21°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 30 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 Showers Rain, Showers Rain, Fog, Light Showers Rain, Fog, Mist, Patches Fog. Temporary LIFR conditions are forecast with Showers Rain, Fog between 06:00Z and 10:00Z. Temporary LIFR conditions are forecast with Light Showers Rain, Fog between 10:00Z and 21:00Z. Temporary IFR conditions are forecast with Mist, Patches Fog between 21:00Z and 00:00Z.

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.

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