Weather Briefing

MVFR

Dunby Manor Heliport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,800 feet and 15 SM visibility.

Wind Analysis

Winds are from the north-northwest (340°) at 15 knots with gusts to 21 knots. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is 15 SM. The ceiling is 1800 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 5°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 27 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Rain, FCST. Temporary MVFR conditions are forecast with Light Rain between 15:00Z and 23:00Z.

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.
