FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 170° at 8 kt, visibility 10 SM, ceiling 8,000 ft. Forecast suggests tonight showers and thunderstorms likely then slight chance showers and thunderstorms, low near 27F, 73% chance of precipitation. Key risks: high density altitude; thunderstorms in the forecast; strong winds in the forecast. Note: the NWS forecast for now reads "Showers And Thunderstorms Likely" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.
