FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 190° at 3 kt, visibility 10 SM, ceiling 3,300 ft. Forecast suggests tonight chance light rain, low near 46F, 45% chance of precipitation. Key risks: no significant hazards are highlighted right now, but always confirm against an official briefing. Note: the NWS forecast for now reads "Slight Chance Light Rain" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.
