FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 180° at 6 kt, visibility 10 SM, ceiling 11,000 ft. Forecast suggests thursday chance rain showers then mostly sunny, high near 83F, low near 56F, 67% chance of precipitation. Key risks: strong winds in the forecast. Note: the NWS forecast for now reads "Chance Showers And Thunderstorms" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.
