Weather Briefing

MVFR

Quad City International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,300 feet and 10 SM visibility.

Wind Analysis

Winds are from the north-northwest (330°) at 9 knots. Runway 31 is favored with a 8-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 1200 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 22°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 20 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Thunderstorm Rain, Mist. There is a 30% probability of MVFR conditions with Thunderstorm Rain, Mist between 21:00Z and 00:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.

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.
