FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 320° at 3 kt, visibility 10 SM, ceiling 19,000 ft. This report is older than usual, so treat it with caution. Forecast suggests this afternoon chance light rain, high near 56F, low near 40F, 53% chance of precipitation. Key risks: thunderstorms in the forecast. Note: the NWS forecast for now reads "Chance Light Rain" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.
