Weather Briefing

VFR

Quad City International Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the west-southwest (250°) at 15 knots with gusts to 22 knots. Runway 23 is favored with a 14-knot headwind and 5-knot crosswind component (gusting to 8 knots crosswind). Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 36°C (97°F) with a dewpoint of 25°C, indicating relatively dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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: Thunderstorm Rain, Mist, Haze. There is a 30% probability of MVFR conditions with Thunderstorm Rain, Mist between 21:00Z and 00:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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 Quad City International Airport

Overview

Quad City International Airport serves the Moline, Illinois metropolitan area as a medium-sized airport situated at 590 feet MSL. Located at coordinates 41.448502, -90.507500, the airport provides critical aviation infrastructure for the Quad Cities region, supporting commercial, general aviation, and potentially military operations.

Flying Conditions

Weather conditions at KMLI demonstrate significant variability, with Visual Flight Rules (VFR) predominating at 68.6% of observed periods. Winds typically blow from the west (270°) at an average of 8.9 knots, with occasional gusts up to 32 knots and calm conditions occurring 15.3% of the time. Seasonal temperature ranges from -24°C to 35°C, with September through November offering the most consistent VFR flying conditions.

Notable Features

The airport features three runways with substantial length: Runway 09/27 at 10,002 feet, Runway 13/31 at 7,001 feet, and Runway 05/23 at 4,509 feet. All runways show 100% favorable wind alignment, with relatively low average crosswind components ranging from 4.2 to 6.2 knots. Visibility averages 9 statute miles, with limited periods of reduced visibility (below 3SM occurring 3.2% of the time).

Approach Considerations

Pilots can expect consistently good wind conditions across all runways, with minimal crosswind challenges. Instrument meteorological conditions occur in 12% of observations (8.5% IFR, 3.4% LIFR), suggesting the importance of having alternate approach strategies. The extensive 10,002-foot Runway 09/27 provides substantial landing and takeoff options for most aircraft types.
