Weather Briefing

VFR

Whiteman Air Force Base is currently reporting visual flight rules (VFR) conditions with broken clouds at 4,700 feet and 10 SM visibility. Note: This observation is 2.7 hours old and conditions may have changed.

Wind Analysis

Winds are from the south-southwest (210°) at 20 knots with gusts to 26 knots. Runway 19 is favored with a 19-knot headwind and 7-knot crosswind component (gusting to 9 knots crosswind). Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 4700 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 32°C (90°F) with a dewpoint of 23°C, indicating moderate moisture 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 30 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 RAGR, Light Showers Rain. Winds are forecast to reach up to 30 knots during the period. Expect variable wind speeds ranging from 10 to 30 knots. Temporary IFR conditions are forecast with Thunderstorm RAGR between 00:00Z and 02:00Z.

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 Whiteman Air Force Base

Whiteman Air Force Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.

Overview

Whiteman Air Force Base is located near Knob Noster, Missouri, serving as a strategic military aviation facility at 870 feet mean sea level. The base hosts a substantial 12,400-foot concrete runway (01/19), capable of supporting complex military aircraft operations. Its central US location provides critical infrastructure for strategic air mobility and defense missions.

Flying Conditions

Weather conditions at Whiteman AFB demonstrate significant variability, with Visual Flight Rules (VFR) predominating 74% of observations. Temperature ranges from -16°C to 37°C, presenting diverse operational challenges throughout the year. Winds predominantly originate from the south at an average of 8.1 knots, with occasional gusts up to 29 knots, and calm conditions occurring 10.1% of the time.

Notable Features

The airport's single runway (01/19) demonstrates favorable wind alignment, with crosswinds averaging only 4.4 knots. Visibility typically remains excellent, averaging 9.5 statute miles, with restricted visibility (below 3SM) occurring in just 1.4% of observations. Fog events are relatively infrequent, affecting only 3.9% of recorded periods.

Approach Considerations

September, October, and January represent the most consistent VFR months for aviation operations. The runway's extensive 12,400-foot length provides substantial margin for diverse aircraft types and operational requirements. Pilots should anticipate predominantly southern wind patterns and prepare for potential marginal conditions during the roughly 25% of time when flight rules are not strictly VFR.
