Weather Briefing
MVFRStinson Municipal Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,300 feet and 10 SM visibility.
Wind Analysis
Winds are from the south-southeast (160°) at 8 knots. Runway 14/32 is favored with a 8-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1300 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 22°C (72°F) with a dewpoint of 20°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Temporary MVFR conditions are forecast between 09:00Z and 13:00Z.
Pilot Recommendations
VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
