Weather Briefing

VFR

La Crosse Regional Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 8,500 feet.

Wind Analysis

Winds are from the west (270°) at 12 knots. Runway 31 is favored with a 9-knot headwind and 8-knot crosswind component.

Visibility & Ceiling

The ceiling is 7000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 20°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 21 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 Thunderstorm Rain, Patches Fog.

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.

About La Crosse Regional Airport

Overview

La Crosse Regional Airport serves the La Crosse metropolitan area in Wisconsin, situated near the Mississippi River at an elevation of 655 feet MSL. The airport features three runways with varying lengths, accommodating regional commercial, general aviation, and potential military traffic in a diverse geographical region.

Flying Conditions

Weather conditions at KLSE demonstrate significant variability, with visual flight rules (VFR) prevailing 65.3% of the time and marginal VFR conditions occurring 24% of observations. Temperature ranges from -29°C to 32°C, with prevailing southerly winds at an average of 8.1 knots, suggesting relatively moderate wind conditions for most operations.

Notable Features

The airport's three runways offer flexible operational capabilities, with the longest runway (18/36) measuring 8,537 feet of concrete surface. All runways demonstrate 100% favorable wind alignment, which provides pilots consistent approach options regardless of wind direction. The airport's moderate elevation and geographic location suggest potential for thermal and terrain-influenced wind variations.

Approach Considerations

Pilots should anticipate predominantly southerly winds with an average crosswind component between 3.7 and 5.9 knots across runways. October, September, and November represent the most favorable VFR months, offering the most consistent visual flying conditions. When planning approaches, consider the airport's visibility average of 8.9 statute miles and potential for occasional reduced visibility during 4.1% of observations.
