Weather Briefing

MVFR

Rosecrans Memorial Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 3,800 feet and 10 SM visibility. Note: This observation is 4.7 hours old and conditions may have changed.

Wind Analysis

Winds are from the northwest (320°) at 14 knots with gusts to 30 knots. The significant gust spread of 16 knots may cause challenging turbulence on approach. Runway 31 is favored with a 14-knot headwind and 2-knot crosswind component (gusting to 5 knots crosswind). Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 2500 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 22°C (72°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Thunderstorm Rain. There is a 30% probability of MVFR conditions with Light Thunderstorm Rain between 10:00Z and 12:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. Gusty conditions may exceed demonstrated crosswind components for many general aviation aircraft. Check your aircraft's limitations.

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.
