Weather Briefing
MVFRPetersburg James A Johnson Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 3,400 feet and 10 SM visibility.
Wind Analysis
Winds are calm, presenting no crosswind concerns for any runway.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 2200 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 6°C (43°F) with a dewpoint of 6°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 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Showers Rain. Temporary MVFR conditions are forecast with Light Showers Rain between 09:00Z and 12:00Z. Temporary MVFR conditions are forecast with Light Showers Rain between 21:00Z and 01:00Z.
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.
