Weather Briefing

VFR

Portland Hillsboro Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 4,300 feet and 10 SM visibility.

Wind Analysis

Winds are from the west-northwest (300°) at 4 knots.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 4300 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 10°C (50°F) with a dewpoint of 7°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 24 hours. Conditions are expected to remain VFR throughout the forecast period.

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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
