Weather Briefing

VFR

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

Wind Analysis

Winds are from the southeast (130°) at 11 knots. Runway 14/32 is favored with a 11-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: few at 10,000 ft.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 19°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: Thunderstorm Rain, Mist, Thunderstorm Rain. Expect variable wind speeds ranging from 4 to 18 knots. Temporary IFR conditions are forecast with Thunderstorm Rain, Mist between 18:00Z and 20:00Z. There is a 30% probability of MVFR conditions with Thunderstorm Rain between 20:00Z and 00:00Z.

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.

Flying Conditions

Weather conditions at KEAU demonstrate significant variability, with visual flight rules (VFR) prevailing 61.7% of the time and marginal VFR conditions occurring 24% of observations. Pilots can expect predominantly westerly winds averaging 7.5 knots, with temperature ranges extending from -31°C to 31°C, creating potential for diverse meteorological challenges throughout the year.

Notable Features

The airport features two intersecting runways: Runway 04/22 measuring 8,101 feet and Runway 14/32 measuring 4,999 feet, both providing concrete surfaces. Both runways demonstrate 100% favorable wind coverage, with Runway 04/22 experiencing an average crosswind of 5.3 knots and Runway 14/32 experiencing an average crosswind of 4.1 knots.

Approach Considerations

Seasonal considerations suggest October, September, and November offer the most consistent VFR conditions for operations. Visibility averages 8.5 statute miles, with only 6.3% of observations showing visibility below 3 statute miles. Pilots should be prepared for occasional fog, which occurs in 5.4% of observations, and plan accordingly with appropriate alternate airport selections.
