Weather Briefing

VFR

Chippewa Valley Regional Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 12,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the south-southeast (160°) at 13 knots. Runway 14/32 is favored with a 12-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 12000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 13°C (55°F) with a dewpoint of 10°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Thunderstorm Rain. Temporary MVFR conditions are forecast with Light Thunderstorm Rain between 00:00Z and 04:00Z.

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.
