Weather Briefing

MVFR

Ontario Municipal Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,800 feet and 3 SM visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is 3 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 2800 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 32°C (90°F) with a dewpoint of 12°C, indicating very dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

Forecast Outlook

The TAF forecast covers the next 24 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Smoke.

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 forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

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