Weather Briefing
MVFRSioux Gateway Airport / Brigadier General Bud Day Field is currently reporting marginal VFR (MVFR) conditions with clear skies and 5 SM visibility.
Wind Analysis
Winds are from the southeast (130°) at 3 knots.
Visibility & Ceiling
Visibility is 5 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 23°C (73°F) with a dewpoint of 22°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. Conditions are expected to remain VFR throughout the forecast period.
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 Sioux Gateway Airport / Brigadier General Bud Day Field
Overview
Sioux Gateway Airport serves the Sioux City metropolitan area in Iowa, strategically located in the upper Midwestern United States. As a medium-sized airport with two substantial runways, it supports regional commercial, general aviation, and potential military operations. The airport honors Brigadier General Bud Day, recognizing its connection to military aviation history.
Flying Conditions
Weather conditions at KSUX demonstrate significant variability, with Visual Flight Rules (VFR) predominating 70.2% of observed periods. Pilots can expect northwest winds averaging 9.9 knots, with temperature ranges spanning from -25°C to 33°C. Seasonal transitions in September, October, and January offer the most consistent VFR conditions, while winter and early spring present more challenging meteorological environments.
Notable Features
Situated at 1,098 feet mean sea level, Sioux Gateway Airport features two concrete and asphalt runways with substantial lengths: Runway 13/31 at 9,002 feet and Runway 17/35 at 6,600 feet. Both runways demonstrate nearly 100% wind compatibility, with minimal average crosswind components of 3.8 and 5.2 knots respectively. Visibility typically exceeds 9 statute miles, with only 3.1% of observations reporting visibility below 3 miles.
Approach Considerations
Prevailing northwest winds (315 degrees) significantly influence approach strategies, providing consistent runway alignment opportunities. The extensive 9,002-foot primary runway offers considerable operational flexibility for diverse aircraft types. Pilots should anticipate potential reduced visibility during 4.7% of observations involving fog, particularly during seasonal transition periods.
