Weather Briefing

VFR

Rosecrans Memorial Airport is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility.

Wind Analysis

Winds are from the south-southwest (200°) at 13 knots with gusts to 21 knots. Runway 17/35 is favored with a 11-knot headwind and 7-knot crosswind component (gusting to 11 knots crosswind).

Visibility & Ceiling

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

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 13°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 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions.

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 Rosecrans Memorial Airport

Overview

Rosecrans Memorial Airport serves St. Joseph, Missouri, as a medium-sized airport positioned at 826 feet above mean sea level. Located at coordinates 39.771900, -94.909698, the airport provides critical aviation infrastructure for the regional transportation network. Its dual runway configuration supports diverse operational requirements for both local and transient aircraft.

Flying Conditions

Statistical data indicates favorable flying conditions, with 73.8% of observations reporting VFR conditions. Seasonal temperature variations are significant, ranging from -18°C to 34°C, with an average temperature of 7.6°C. Wind patterns predominantly originate from the south at an average of 8 knots, with calm conditions occurring 26.5% of the time and maximum gusts reaching 30 knots.

Notable Features

The airport features two runways: Runway 13/31 at 4,797 feet with a pavement surface, and Runway 17/35 at 8,059 feet with a concrete surface. Both runways demonstrate excellent wind alignment, with 100% favorable wind conditions and minimal average crosswind (4.4kt and 3.9kt respectively). Visibility averages 8.5 statute miles, with occasional reduced conditions including fog events affecting 16.4% of observations.

Approach Considerations

Pilots should anticipate the most consistent VFR conditions during September, October, and January. With both runways demonstrating full wind compatibility, selection can be made based on aircraft performance and current wind vector. Visibility restrictions occur in 5.2% of observations with conditions below 3 statute miles, suggesting potential need for instrument procedures during certain meteorological conditions.
