FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category MVFR, wind from 90° at 11 kt, visibility 10 SM, ceiling 1,200 ft. Forecast suggests today isolated showers and thunderstorms, high near 88F, low near 77F, 17% chance of precipitation. Key risks: thunderstorms in the forecast. Note: the NWS forecast for now reads "Isolated Showers And Thunderstorms" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.
