Weather Briefing

VFR

Austin Straubel International Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 4,400 feet and 10 SM visibility.

Wind Analysis

Winds are from the east (90°) at 7 knots. Runway 06/24 is favored with a 6-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 3600 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 18°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 22 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, Thunderstorm Rain, Mist, Mist. Temporary MVFR conditions are forecast with Light Thunderstorm Rain between 15:00Z and 17:00Z. Temporary IFR conditions are forecast with Thunderstorm Rain, Mist between 21:00Z and 01:00Z.

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.

About Austin Straubel International Airport

Overview

Austin Straubel International Airport serves Green Bay, Wisconsin as a medium-sized airport with substantial runway capacity. Located at coordinates 44.483459, -88.130805 and elevated at 695 ft MSL, the airport provides critical transportation infrastructure for northeastern Wisconsin. The airport features three runways with substantial lengths, enabling diverse aircraft operations.

Flying Conditions

Weather conditions at KGRB demonstrate significant variability, with visual flight rules (VFR) predominating at 65% of observations. Temperature ranges dramatically from -28°C to 31°C, requiring pilots to prepare for extreme thermal conditions. Prevailing westerly winds at an average of 8.4 knots with occasional gusts up to 26 knots characterize the airport's wind profile, with calm conditions occurring 14% of the time.

Notable Features

The airport's three runways offer comprehensive operational flexibility, with two concrete runways (06/24 at 7700ft and 18/36 at 8201ft) and one asphalt runway (12/30 at 3198ft). All runways demonstrate 100% favorable wind alignment, with modest average crosswind components between 5-5.7 knots. Visibility averages 8.7 statute miles, though pilots should anticipate reduced visibility scenarios where conditions drop below 3 miles in 5.4% of observations.

Approach Considerations

Optimal VFR flying conditions occur during autumn months (September, October, November), providing the most consistent meteorological environment. Fog appears in approximately 7% of observations, suggesting potential instrument approach requirements. Pilots should anticipate westerly wind influences and prepare for potential instrument meteorological conditions, particularly during shoulder seasons when MVFR conditions represent 21.9% of observations.
