Weather Briefing
MVFRShonai Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,400 feet and 10 miles or greater visibility. Note: This observation is 3.5 hours old and conditions may have changed.
Wind Analysis
Winds are from the southwest (230°) at 2 knots.
Visibility & Ceiling
Visibility is unrestricted. The ceiling is 1400 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 14°C (57°F) with a dewpoint of 12°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.
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.
