Weather Briefing

VFR

Jackson-Medgar Wiley Evers International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 9,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the north (360°) at 7 knots. Runway 34 is favored with a 7-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 9000 feet AGL (broken), well above standard VFR minimums. Caution: cumulonimbus (thunderstorm) clouds reported at 5,400 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 28°C (82°F) with a dewpoint of 26°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 21 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. Temporary IFR conditions are forecast with Light Thunderstorm Rain between 21:00Z and 22:00Z.

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 Jackson-Medgar Wiley Evers International Airport

Overview

Jackson-Medgar Wiley Evers International Airport serves the Jackson metropolitan area in Mississippi, operating as a medium-sized airport with dual parallel runways. Located at 32.311199, -90.075897 with an elevation of 346 feet MSL, the airport provides critical aviation infrastructure for central Mississippi. Both primary runways measure 8500 feet in length and are constructed with asphalt surfaces.

Flying Conditions

The airport experiences predominantly Visual Flight Rules (VFR) conditions, with 69% of observations supporting VFR operations. Seasonal temperature variations are significant, ranging from -6°C to 37°C, with an average temperature of 16.2°C. Wind conditions are characterized by southerly prevailing winds at an average of 6.7 knots, with calm conditions occurring 25.6% of the time and maximum recorded winds of 21 knots.

Notable Features

Both primary runways (16L/34R and 16R/34L) demonstrate identical wind compatibility, with 100% favorable wind alignment. Average crosswind components are consistently low at 2.9 knots, suggesting generally stable approach conditions. The airport's geographical location contributes to predictable meteorological patterns, with September through November representing the most favorable VFR months.

Approach Considerations

Pilots can expect excellent visibility conditions, with an average visibility of 9.1 statute miles and only 2.3% of observations showing visibility below 3 miles. Instrument meteorological conditions are relatively infrequent, with IFR conditions occurring in 9.4% of observations and LIFR conditions in just 5.8% of cases. The parallel runway configuration provides operational flexibility for approaches from both 16 and 34 headings.
